55 gallon tank question; adding new Damsels    2/19/17
I have a 55 gallon tank with a mated pair of percula clown fish, a red flame hawk fish, and a coral beauty angel.
I would like to add 3 yellow tailed blue damsels. Am I likely to create an aggression problem?
<I give you about even odds here... I'd put the two Perculas in a plastic floating colander for the first 2-3 days the new Damsels are added. Bob Fenner>

Blue Devil beh.!   3/26/14
Hello Crew!
Thank you all for help in the past and I have hopes you can
offer me suggestions/analysis now. I have a Blue Damsel that has recently gone nuts, but was previously peaceful. I’ll start with the history. I have a 55 gallon tank with DSB and maybe 1/5 of the volume is live rock. (60-80 pounds) I got the aquarium 16 months ago and it came with the Damsel. I introduced 2
Clownfish, and the Damsel wouldn’t let them leave their corner. I gave the Damsel a 1 week timeout in my
quarantine tank and when re-introduced it got along perfectly with the clowns for 8 months. Then I added a Royal Gramma, and neither the Damsel nor the Clowns thought anything of it. There was not one territorial display. They all got along for 6 months. One month ago I introduced a Kole Tang. The Damsel made a lot of territorial displays the first day, a few the second day, and then everything has been peaceful in
the tank for 21 days. Two days ago I
watched as the Damsel frantically chased after every single fish. It would swim right up to them and do some kind of fluffed up dance. It would never attack any of the fish. It just harassed each fish till they bit it. It would do
these displays to the Cleaner Shrimp, to certain sections of rock, and to all
the fish. I’ve watched a long time from a distance the last two days and I’ve never seen it actually attack anything, but it harasses the other fish until they finally bite it. The rear fin is a little tattered, but there hasn’t been any serious damage. I’m very confused. Can you offer any opinions on this behavioral shift?
<Does happen at times... perhaps some sort of environmental clues, aging... development... endocrinological... But some individual damsels and especially certain genera (Dascyllus and Stegastes are good ex.s); REALLY become MEAN>
I find it odd
that this fish is picking fights, but not throwing any blows. The Damsel’s swimming is quick, jerky, erratic, sometimes spastic like twitching, and raises it’s fins when bothering the other fish. The only other change I can think of is that the Damsel is now eating the Nori that I now feed the tank. So, the fish’s diet is a little different. Did vegetables drive this fish crazy?
<Doubtful... likely hormones>
Any help is much appreciated.
<A good idea to trade this fish in... or move to a larger system w/ some of its own species to interact with. Bob Fenner>

you so much for the quick response. I

Royal Gramma Aggression Question     1/21/14
Hi Crew,
<Hi Kyle>
Sorry to bug you with such a trite question, but I was hoping you could lend a little knowledge on a quick compatibility quandary.
<That's why I'm here.>
 My neighbor is breaking down his tank and has offered me some livestock.
The only fish I'm interested in would be his Starcki's Damsel (Chrysiptera starcki). I've observed it in his tank for the better part of a year and never seen anything aggressive from him, and it is my understanding that Starki's are more mild than most other damsels.
<In my experience.>
 I would be adding him to my 150g reef, but I'm worried that he would be aggressive toward my Royal gramma (Gramma loreto) due to color/pattern similarities and both fish potentially being territorial. What are your thoughts?
<I have three Starcki Damsels and a Gramma in a four foot ninety gallon.
The Damsels squabble among themselves but rarely pay notice to anything else. Gramma sticks to his cave and waits for dinner.>
 Naturally the gramma is my wife's favorite fish, so jeopardizing it could cause some "territorial aggression" on the home front :)
<The tank is large enough that aggression between the two should not be an issue.>
Thanks for the help and keep up the good work!
<Quite welcome.>

Damsel ID     9/27/13
Hi Bob,
          I have attached a picture <<Someone else's work>> of a damsel I have seen a few times in the past and today in my LFS here in the UK. It was labeled as a tricolour damsel, Chrysiptera rollandi .
It doesn't look like the Chrysiptera rollandi in your damsel section within WetWebMedia,
<Here for browsers: http://www.wetwebmedia.com/chrysiptera.htm
 and confusingly, photo's on the web show fish like the one I seen today and others which are dissimilar under the same name.
Is this the juvenile form of Chrysiptera rollandi, or a variant?
<Is an adult colored specimen; the species shows quite a variance juvenile to adult, and some regional variation. See here for Fishbase.org: http://www.fishbase.org/Photos/ThumbnailsSummary.php?ID=5486 >
 I like the colour of the fish in the picture I've attached but I'm not so keen on the photo on your website. Thanks for the invaluable help you provide, Toby
<Ah, welcome. If you think some of the Pomacentrids are confusing in this coloration matter, take a look at the Labrids!
Cheers, Bob Fenner>

Blue Sapphire Damselfish (Chrysiptera springeri) compatibility    6/28/13
I would like to keep the following in a 220 gallon tank.
The tank will have lots of live rock, hiding places and broken sight lines.
1 Flame Angel
1 Coral Beauty
1 Heralds Yellow Angel
<Can be quite boisterous.>
7 Blue Sapphire Damsels (Chrysiptera springeri)
A few Blennies
The Blennies would be introduced first, the Damsels second and the Dwarf Angels last.
<I would add the Damsels last. Allowing the Centropyge to establish territory unharassed would be my primary concern.>
The question I have is;  How aggressive will the Chrysiptera springeri be in this setup?
<Large enough system that they should not be of notice. I would be more concerned with a Centropyge death match.>
I have read conflicting reports about this damsel's peacefulness or aggression.
Does anyone have direct experience with a small group of these damsels kept in a larger aquarium?
<I have kept groups of three to five with similar stocking and the Springer's just squabble amongst themselves for the most part. Mild harassment but nothing of concern.>
  Will they become super territorial and kill everything in the tank
when they mature?
<They will not grow large enough to pose a serious threat to your current stock list.>
Thanks for your help,

Chrysiptera rollandi, sel./stkg./comp.     7/20/12
Hi crew of WWM,
First I would like to say thanks for a wonderful site! But now for the question. I saw two Chrysiptera Rollandi at my LFS, and would like to know if they could successfully live in a 35 Gal tank?
<A bit tight, but w/ enough break up (decor, rock...) of the environment, likely do-able>
 I just want to know if one would bully the other.
<IF started small, likely not "too much" so>
Thanks again,
<Welcome. Bob Fenner>

Damsel Compatibility... not    3/15/12
Howdy, I bought two yellow tail damsels (species recommended by Salty Dog as my first fish).  One is bullying the other making him stay up in a corner
<Very common behavior>

 (got them last Wednesday, so it's been a week).  I want to check on what the pet store said which was that what MIGHT happen is the bully will become the female and they will become a mated pair.
<Not likely. The one will cause the others demise>
  So one question I have is that if this does not happen, should I remove one of the fish?
<Yes I would>

 I have a 28 gallon bow front tank by the way.  My other question is, as I was reading through your articles and FAQs on damsels, I came across the Talbot Damsel and would like to add one to my tank.  I only have the yellow tails so far.  Thanks for the info!  Paul
<The Talbot may be sufficiently "different" to get along w/ the single Chromis. Bob Fenner>
Re: Damsel Compatibility, hlth.    3/15/12

Thanks for the response, that's too bad.  Well, if I'm going to move one out anyway, the one that gets bullied has some discoloration on his lips.
<I see this... very bad... Mouth damage in small fishes often leads to death>
I didn't notice it in the pet store, but I did right after putting him in the tank.  They seem more clear then white, but the pics show up white.
There is also slight white around both eyes that was not there before.  If you think it's a disease I'll take him out now, but the pet store thought it was an injury, so I've just been waiting for it to heal.  Thanks.
<Is very likely due to injury... BobF>

Re: Damsel Compatibility...     3/23/12
Hello again, I was hoping to give an update saying that all is well with my poor yellow tail damsel, but he stopped eating two days ago, and this morning I noticed a small red spot on his puffy lips (which seem to be a little puffier also) sort of like they are cracking open. 
<The end>
After reading your response that he may die from the injury anyway, I decided to just keep him around
<... needed to be separated>
 rather than give him to the pet store (kind of a way to let him die peacefully without even more stress of being recaptured and moved).
Also, I was going to move him to a 10gal refugium once I got that set up to stop the bulling, but now I'm wondering if this will turn to some sort of disease that will contaminate my tank, and should I just net him and flush the poor fellow?  Oh, and I also have some isopods, letting you know in case they might be making the blood spot.  Thanks, Paul.
<... B>
Re: Damsel Compatibility    3/23/12

Well, I'm saddened.  Is it worth trying to give him away or take him back to the pet store? 
My guess is no, but I'd rather him not die if there was hope for that.  I guess the lesson I learned this time is to listen to sound advice!  Thanks again.
<Doomed. B>

Re: Damsel Compatibility    4/5/12
You, of course, were right, and the injured and harassed yellow tail damsel died.  So a couple of weeks went by and I bought a Talbot damsel as you thought a Talbot might be un-harassed by the bully.  I even bought 2 more rocks and mixed everything up to disturb his territory, but alas, he seems to just like to harass other fish.  The Talbot is usually under that rock (shown in the picture) and even there the yellow tail finds the hiding fish a chases him out of there.  We got the Talbot on Monday ('tis now Thursday) and just wanted your thoughts.  My wife thinks I should give them more time to become friends, but I doubt that's possible now.  Thanks.
<I'd trade in the aggressor. BobF>

Yellowtail Blue Damsel Or Not? Stkg/sel.     5/12/11
Bob and Crew,
I was wondering if I would be able to add three Yellowtail Damsels (Chrysiptera parasema) to my tank. Current setup is 75 gallon soft coral tank, running two 175 watt metal halide lights, on for 8 hours a day. Two 110 watt VHO 454 Actinics, on for 12 hours. 15 gallon sump with a Mag 9 for return, Aqua C EV-180 protein skimmer with Mag 7. Two Maxi-Jet 600 and one Maxi-Jet 900 for added circulation in tank, with 85 pounds Fiji live rock and 4 inch sand bed. I run Activated Carbine changed out monthly and do 10% water changes weekly. Tank has been running for little over a year now, with zero Ammonia, Nitrite, Nitrate, and a Ph of 8.2-8.4. For corals I have two Branching Sinularias, two Toadstool Leathers, a Red Colt, Green Star Polyp, and Neon Centered Clove Polyps. For inverts I have two Skunk Cleaner Shrimp, 5-10 Astrea Snails, 5-10 Cerith Snails, 5-10 Nassarius Snails, and a sand sifting Sea Cucumber. For Fish I have two Clownfish True Percula (Amphiprion percula), two Banggai Cardinals (Pterapogon kauderni), a Coral Beauty (Centropyge bispinosus), and a Clown Fairy Wrasse (Cirrhilabrus solorensis).
<Should get along w/ these. Do look for not-too-tiny Damsel specimens. Small ones tend to die easily>
All fish were quarantined a month before adding, and are getting along great. The Yellowtails would be the last fish in the tank. I am just looking to add a little more color and I love the blue and yellow combo.
If the Yellowtails are too mean for my tank then I could add a Royal Gramma, which would add the same color effect. There just not as active.
I appreciate your time, and apologize ahead of time for the grammar mistakes.(Which I'm sure there are, but in my defense I did run Spell Check.)
<I do think these would be a nice addition Jaime. Color, behavior-wise.
Cheers, Bob Fenner>
Re: Yellowtail Blue Damsel Or Not?    5/12/11
Thanks so much for your fast response. One more question I forgot to ask, would it be alright to quarantine all three yellowtails in a 10 gallon bare bottom tank?
<Actually... I'd just dip/bath them (pH adjusted freshwater) as gone over on WWM and summarily place in the main/display tank>
I know in tight quarters they might fight with each other. I do have a 20 long that is just laying around I could use if the 10 is not big enough, it just takes a little more energy to heat and the bill is already high.
Thanks again for your time, the fact that you and the crew donate your time on all these questions is amazing.
<Welcome... the SOP will knock off most any/all external issues, and the quarantine is too stressful. BobF>

Chrysiptera parasema/Damsels/Compatibility 10/21/10
Hi WWM crew.
<Hello Nico>
I have a 105 gallon reef tank filled with lots of soft corals and a few LPS corals that is currently populated by 1 black Ocellaris Clownfish, 1 Green Chromis, 1 Midas Blenny, 1 Banggai Cardinal and 1 Blackfin Dartfish.
The tank has been up and running for more than 1 year and the Black Dartfish was the last one I purchased and has been in the tank for more then 3 months.
<Very nice looking tank!>
I've been looking for a reef safe fish that stay's relatively small and has that eye-popping blue that so few fish possess.
If not for they're dubious reputation regarding corals, Centropyge argi would have been my first choice.
Would it be OK to introduce 1 Chrysiptera Parasema into my aquarium?
<Certainly, a relatively peaceful damsel, one of my favorite.>
Sometime in the future ( when one of the LFS has one for sale ) I would like to complete my setup with 1 Serranus tortugarum and 1 Synchiropus picturatus ( if I can find a nice fat one that's at least willing to eat some frozen food ).
<Yes, the Mandarin can be difficult to acclimate to prepared foods. Would be a good idea to introduce some live pods in the tank and introduce the Mandarin a few months later.
A good size pod colony should have developed by then.>
Should I wait until I have purchased all the other fish on my wish list and introduce the Damselfish last?
<With that group, it should not matter much who goes in last.>
<You're welcome. James (Salty Dog) from Michigan, USA
Nico from Belgium

Re Chrysiptera parasema/Damsels/Compatibility 10/21/10 - 11/4/10
<Hello Nico>
Thanks for the quick reply ( had some internet provider problems , so I could not read your reply till today ).
I have 1 more question.
Would 1 yellow tail Damsel be best in this setup or would a group of 3 or 5 be better?
<Is your choice to make here. Loners do well, no problem in that regard.>
<James (Salty Dog)>

Mixing Damsels With Niger Trigger/Triggerfish/Compatibility 2/5/10
I have a 125 gallon FOWLR with a Niger Trigger (about 4 inches) and a Fox Face (also about 4 inches). The tank has been setup for about 2 years. I would like to add 3 to 5 Yellowtail Damsels to add color and movement. Is
this reasonable, or would it create problems either for the existing or new inhabitants?
<You would be placing the damsels in an environment not to their liking, they will be at risk. James (Salty Dog)>

Re: Mystery white stuff? Now Damsel ID 10/9/2009
Thank you again Mike. Will put all your suggestions into practice.
<Hi Liz. Good to hear.>
One last question for you. Any idea what kind of damsel this is (see attached picture)? It came with my tank, previous owner had no idea what it was.
<Damsels can be very tricky to identify. The cute little colorful fish you buy in the store usually morphs into something that looks much different when it grows up.>
It's color changes from a dark blue/purple to a washed out various of the same as it swims around the tank. Very personable, busy fish. Has staked out it's corner of the tank and is otherwise very tolerant of the two pesky Sgt. Majors and isn't concerned at all with the Cardinals.
<Really need some more information to even attempt an identification better than a guess. Information like size and how long one has had the fish is helpful. Many damsels change their colors as they mature. If one were to force me to make an ID, my best guess would be a member of the Neoglyphidodon genus that is in the process of color changing.
http://www.wetwebmedia.com/neoglyphidodon.htm >
It does do something odd with the eel. I've noticed several times when the eel sticks it's head up out of the rock at the back of the tank the Damsel will swim over, invert its self so it's head is pointed straight up towards the top of the tank and then stay there by the eel. Sometimes still, sometimes 'wagging' it's hind end. I assume this is some sort of posturing, but it doesn't seem real aggressive. The eel isn't bothered by it at all!
<Posturing because the eel is too close to the damsels territory is most likely.>
I sure wish I knew someone like you locally. I have *so* many questions.
<Do have a look on this page - http://www.wetwebmedia.com/damsels.htm Has links to the different types of damsels
Take care,
<Will do>

Re: Mystery white stuff? Now Damsel ID 10/12/2009
<Howdy Liz.>
I had no idea damsels could color morph so amazingly.
<Yep. Unfortunately, they usually become very drab as adults.>
Sadly, I don't have much background info on the fish. It came with the tank when I bought it and the precious owner didn't know what it was either.
Which kinda stymies me. I've been obsessively cataloging and identifying everything large and small living in my tank.
Here is what I do know about the fish:
- about a year to a year and a half old
- 3 1/2" long excluding tail fin <Close to being an adult then.>
- in the tank the color of the fish changes pretty dramatically as it swims.
Sometimes it looks very vivid (like in the picture), sometimes it looks like a washed out version of the same colors. Just depends on how the light hits it.
<Or the fish's mood.>
Not much to go on. I suppose specific ID isn't critically important, but I do like knowing what I have when possible!
<Do keep digging around - http://www.fishbase.org is an excellent reference as well.>

Re: Centropyge Compatibility Question-- 08/14/09
Galba's Chrysiptera! Its beautiful - I love it! I had just automatically assumed that anything in the damsel family would be too aggressive for my tank (with the gobies and all) - which is why I was so leery about the
yellow tail blue damsels.
<This genus... and a few others are notable exceptions>
If I may impose one last time - will a single canary demoiselle thrive or is it best to keep them in a small group?
<Are fine singly; though you can have more than one in this size system>
Should they be added before or after a flame angel?
<Before is best>
Thank you so much for the direction!
<Welcome! B>

Fish ID 06/08/09
I was given my first saltwater aquarium a few weeks ago, with fish by a friend. She went bigger and gave me the fish that came with her tank bigger tank. I have identified all the fish in the tank except for this one. I was finally able to get a couple of good clear photos of it and have attached them to this email. It is approximately 2-2 1/2 inches long and is always these muted colors.
Thank you, Julie
<Hi Julie. Chrysiptera rex, the spot behind the eye in combination with the coloration (which can be more vivid on other specimens) is typical. Cheers, Marco.>

Re: Fish ID
Thank you so much. We knew it was part of the damselfish family but couldn't figure it out. You guys are awesome. Julie
<Thanks for your kind words. Marco.>

Check this out.... species of Damsel that eats FWs??? 4/16/09
Howdy Bob, Adrian from AZ here.....
So I was in a LFS the other day getting a ballast (never fun) and mentioned to the SW guy named Andy (Pets Inc. in Tempe AZ) that I had a small infestation of Flatworms for about 6 months now. He pointed me to this tank with 2 damsels in it. Says that these blue "Damsels" will eat them, they are not the regular blue damsels. SURE I said, but decided to take him home and give it a shot. Well its been about a month now and he gets along GREAT with my female Picasso clown (who is a real you know what) and there is no sign whatsoever of Flatworms. CRAZY. So I thought I would send this to you, for your posting pleasure on WWM and maybe you can ID the damsel, maybe just a common blue damsel? Anyway Enjoy and will talk soon!!!
Fish and Reef Aquarium Group
<Thanks much for this Adrian. Will post, share. BobF>

Check this out.... species of Damsel that eats FWs??? 4/16/09
Hi there Bob,
I think that pretty little flatworm eating fish just might be a Springer's Damsel/Blue Sapphire Damsel, aka Chrysiptera springeri:
Take care,
<I do agree... and will attach your ID. BobF>

Blue damsels, beh.  3/2/09 Hi i have 2 blue damsels, 1 smaller and 1 larger, the larger one has begun getting spotted, instead of all neon blue his spots are a darker blue. I thought it was just when he came out from being in a dark place but now its almost all the time. I heard that it might have something to do with the smaller damsel, and the larger one wanting to mate. But im not sure. Thanks <Mmm, not likely an issue... Behavioral/physiological change. Bob Fenner>

Please help, Chrysiptera hlth.   12/22/08 Hey all, <Steph> For the past few months I've been having an issue with one of my yellowtail damsels (i have two). i have a 20 gallon tank <Mmm> and the temp varies from 81-83 degrees. I've have them for a little over 2 years, so they are used to the temperature and conditions. For the past few months, my one fish has been losing his color at night, and then it will come back once we turn the light on, usually. there are some times however, like right now, where the tank will be on for longer and still no return of color (right now its been on for over and hour). i understand that they do lose color as form of camo, but this is different. Not only does his color fade, his swim pattern is different as well. he swims near the top of the water or stays in a corner at the very bottom, he bumps into things, sometimes he swims around lethargically, other times he's quick and jolty. <Good description> our second fish rarely acts like this, sometimes he does lose his color, but other than that he's pretty normal. what can be wrong with the first fish? <Reads like nutritional deficiency, spawning/social behavior, or  senescence/old age...> all levels in the tank are where they should be. i don't think anything is wrong with my tank, because then my other fish would be affected.....I've researched as much as i could and always come up empty. Please help, Stephanie, Spike and McNabb <You can try supplementing the food... Zoe, Selcon, SeaChem's Vitality..., moving the hard elements of the tank about... for the first two... Bob Fenner>

Chrysiptera parasema Compatibility 9/21/08 I have a Blue Tang (Paracanthurus hepatus), Yellow Tang (Zebrasoma flavescens), Foxface (Siganus unimaculatus), and a clownfish (Amphiprion ocellaris) in my 75 gallon mixed reef. I purchased these relatively small approximately a year ago and now they've all grown up. True to my word, I have purchased a 135 gallon tank to upgrade to so that they can stretch their fins a little more. <Wonderful to here, I wish it was the case more often than not.> I was entertaining the idea of adding perhaps 3-5 yellow-tail damsels (Chrysiptera parasema) to the mix but was concerned about aggression. I had planned to move the existing fish to the 135 and let them get adjusted for a few weeks before adding the damsels. Also, I will have 2 areas in the tank with no rock and I have cut a piece of eggcrate which I can put in the tank to section off a small area in order to let new arrivals get adjusted and also aid in catching anything that needs to come out. How do you rate my chances for success with this setup? <I think you have a high likelihood for success. Although with time, I suspect this will be too small a tank for these tangs. These Yellow-tail Damsels are some of the least aggressive of the damsels. In fact, you might have problems with other fish picking on them. I like your eggcrate idea. I'd love to see a picture.> Thanks for the advice. <Welcome, Mich>

Damsel Question, sys., env. hlth.   4/27/08 Hello. I enjoy reading your posts and some have been very useful. I have a nano-tank(6Gal), with two blue damsels. <Misplaced here. Need more room psychologically> I cycled the tank, checked all my levels, etc. I waited 2 weeks to add the fish and they have been in there now over a month. The ammonia is nil and the other levels are within acceptable ranges. The issue I have is one of the damsels spends a lot of time at the top of the tank, almost swimming sideways at times. He also appears to have spots on his side that looks like a human going grey, ie, losing color. He does dart around pretty good, so it is hard to tell if he is sick. The other damsel does bother him frequently but I don't see any frayed fins, etc. I cannot locate any bacteria or other disease that resembles what I am seeing. I am afraid to add a wrasse or more rock until I know if there is a disease. <... is environmental to the largest degree...> Also, as a nano tank, it does get algae quite a bit. I clean it weekly and add water as needed. Is there anything I can do to keep the growth low and can this be something that is affecting my damsel? Thanks for your help. Dale <Please read here: http://wetwebmedia.com/marine/fishes/part2.htm the second to last tray. This fish, these fish, are mis-placed; cannot live well/long in such confines. Bob Fenner>

Chrysip-terror (see what I did there? :) ), sel.   4/26/08 Good evening, The spring has sprung here in the UK, and it's a good time to sit by the tank with the windows open, birds singing and a nice glass of plonk. My question is about damsel's, not the weather though. How many Chrysiptera damsels would co-exist in an 80gal aquarium? <Of what species? Some can be crowded a bit more than others... That being said, likely four to maybe six individuals> They'd be sharing with some tough but non-too-aggressive fish... Papua Toby, wrasse, royal Gramma. I have a couple of plans in mind.. Say for example you think 4 or 5 would be the maximum. Then I'd ideally like to go for something like 1 yellow tail, 1 azure and 2-3 Talbots, or another similar mix like 2 yellow-tail, 2 Talbots and 1 azure... Am I crazy or just stupid to think I could have this many damsels in confined area? <Mmm, no, not crazy. Make for an interesting display> Reading through your site I'm struck by the impression that as mean as they can be to each other (looking at you, Mr Domino), these guys are social animals and much prefer squaring up to each other than peaceful loneliness... <Agreed> I'd really like to do these little gems justice, by getting the right mix and having an interesting, dynamic display. Obviously, the tank would be well split up with live rock shaped into caves, valleys, walls and out-crops. Anyway, keep up the good work! Chris <Thank you for your thoughtful query. Bob Fenner>

Re: Chrysip-terror (see what I did there? :) ), Damsel sel.  - 04/26/08 Thank you so much for your reply Bob. <Welcome Chris> Would it be a real dumb move to swap one of those Chrysiptera for a 4-stripe damsel? They're closely related to domino's I understand, and so could terrorise the others beyond healthy competition? <Not so much this, but I would not swap out this genus for a Dascyllus... the latter are social animals... Really need to be kept in a group... Whereas Chrysiptera are individuals...> Or do you think the mix and tank set-up could allow them all to function together? I only have experience of yellow tail damsels so don't have any idea of how aggressive these humbugs get. Cheers Chris <Some are true terrors... as you state, the Domino, Hawaii's endemic D. albisella... BobF>

Re: Chrysip-terror (see what I did there? :) ) - 04/26/08 Thank you again for your speedy reply Bob, you just have to spend five minutes on wet web to see how busy you guys are. <All volunteer... and/good that many folks here live in disparate time zones, countries... some coverage most all the time, eh?> With regards to groups of 4-stripe...would that be a possibility in this tank? <Mmm, yes... could have a small grouping, let's say 4 or 5 individuals...> My initial idea of a damsel dominated tank could work with a school of humbugs instead of a variety of Chrysiptera's... <Yes... and also very interesting to view> If it is a possibility then how would I go about structuring it? Would, say, a small group of 3-4 humbugs work in this size (80g) tank? <Yes... with two or three principal arrangements of rock, or better open, arborose skeletons or live corals (Acropora, Pocilloporids, Poritids...)> If this is a possibility, would I be sentencing my yellow-tail damsel to a life of bottom-of-the-pile hell if I stuck him in with the humbugs, or do you think he'd just get his fair share of normal damsel attitude from the others in there? <Likely it would be "the odd fellow out", but survive just the same> That might be impossible to answer I guess. Maybe better to avoid any doubt and pack the little guy off elsewhere. <Best to keep this option open> Thank you so much for letting me pick your brain on this. I have a long run-up on getting this tank set up, so am trying to look at it from all angles and check the pro's and con's of each possible combination. If you don't mind me asking, if you got the urge and was setting up a similar tank, what combination of damsels would you go with? Cheers Chris <A tough one... but either of the presented choices would suit my "palate". Cheers! BobF>

Blue Azure Damsel 3/19/08 Is the Blue Azure Damsel peaceful? <Somewhat.> I thought all damsels were aggressive, but I am hearing the Blue Azure is peaceful. The yellow tail is fine, but the yellow belly is very aggressive. Any insight would be appreciated. Thanks. Steve <These are generally less aggressive and for the most part peaceful. They are much more easygoing than say a Domino Damsel. The Blue Azure, Chrysiptera parasema, is a good choice. Welcome, Scott V.>

Re: Blue Azure Damsel, Chrysiptera comp., sel.  3/22/08 Scott, <Hello again Steve.> Thanks for the response. <You're welcome.> Can I house 2-3 Blue Azure Damsels in a 75 gal.? <Yes.> Or is 1 the limit due to space and territory issues? <These particular Damsels do ok together given enough space and rock work to hide.> I have three Green chromis and they get along fine. Not so sure with these damsels. <The Damsels themselves would be fine, I would be hesitant to mix them with the Green Chromis, the Blue Azures will be more aggressive.> Thanks. Steve <Welcome, Scott V.>

Fish Identification... South Seas Devil Damselfish (Chrysiptera taupou)  9/7/07 Hi Bob!! <Mich filling in today.> Hate to bother you once again. <Not bothering me!> So I went to the LFS today. I was thinking I would get a couple of Chromis as my first fish. <...> In the tank it was marked assorted Chromis. I picked out a pair. <This fish is best kept individually.> They are a royal blue color (think UK wildcats) with a white belly. There WERE some blue green Chromis in there but I am thinking more and more these are not what they told me. One of my issues is that I am intending to have a peaceful community tank. (reason being I REALLY want a clown later) <Not with this fish!> Anyway I have taken a pic of the fish in the hopes you can help me. The color is not accurate. As I said it is more of a bright blue with a white belly. You will also notice the black around the eyes as well as the dot on the back. I have looked all over the web for something similar and not had any luck. <Looks like a South Seas Devil Damselfish (Chrysiptera taupou) to me.> Also if you are able to identify can you tell me more about the temperament as well as upkeep of this fish. <Did ya notice the Devil in the common name? That should be a hint! Heehee! This guy's a little bugger! It can be quite belligerent and should be kept in a moderately aggressive tank. Unless the two that you have are a mated pair it is very possible one of these damsels could bully the other to death.> Also it is VERY active. LOL. Fun to watch but if they won't be compatible later on I will have to return them. <This may be the best choice.> Thanks again, <Welcome! Mich> Melissa

Re: Fish Identification... South Seas Devil Damselfish (Chrysiptera taupou)  9/7/07 Mich~ <Melissa,> Thanks so much for your quick reply. <Welcome!> Looks like they are going back today. You are indeed correct. <Ahhh, well, sorry to be the bearer of bad news.> And no they are not a mated pair they are both male at least according to the pics I saw of them. <Yep.> Also would the blue green Chromis make good fish to get along with my future clown? <Mmm, possibly, but it doesn't sound like this fish is really on you list of desirable tankmates. I'm wondering how long you tank has been set up, if you're trying to cycle with these fish? If so there are better ways to cycle your tank with out adding/torturing an innocent fish. Please see here: http://www.wetwebmedia.com/estbiofiltmar.htm If this is really a desired addition then ok, if not, I would just wait till you can add the fish you truly desire, such as the clown.> I'm feeling like I need to take a picture resource with me to ensure what I am buying is what they are telling me. <Might I recommend a book to you called "Marine Fishes" by Scott W. Michael, it's a PocketExpert Guide (read portable) that describes some of the most common aquarium fish including your little devils ;). I should also add, in the same series does Ronald L. Shimek call a book "Marine Invertebrates". I think you will find these a most handy addition to your reference library!> Thanks again,
<Welcome as always!>

Damsel identity... Rolland's Damselfish & Black Cap Damselfish = Chrysiptera rollandi 9/6/07 Hi. I recently purchased a Rolland's Damselfish. <Chrysiptera rollandi> I have seen pictures on the internet of what looks to be an identical fish listed as a Black Cap Damselfish. Are these the same fish? <Yes, just a different common name, one is based on the physical traits, the other on the scientific name and likely the first person to describe this fish.> If not, how do they differ? <They don't.> Thanks! <Welcome! Mich> -Connie

Fish ID at Live Aquaria  8/21/07 Hey There WetWebMedia folks! <Hello there Rich> I was wondering if you would concur with this fish ID for a Chrysiptera rollandi variety at Live Aquaria. http://www.liveaquaria.com/diversden/ItemDisplay.cfm?ddid=23822&siteid=20 <Nice pic... and does appear to be this species: http://fishbase.org/Photos/ThumbnailsSummary.php?ID=5486> Even if he is correctly ID'ed I still have found little info about this species other than the bit on your Chrysiptera page (where the photos as well as the photos on fishbase.org don't look at all like this fellow). <I suspect it is about the same as its congeners in care, temperament> He is a neat looking little fish that I would like to add to my 110 tall FOWLR that has mostly peaceful, small fish including a purple fire fish, algae blenny, royal Gramma, a trio of Carpenter's flasher wrasse,1 perc clown,1 PJ cardinal and I have a Chromis cyaneus in a quarantine tank waiting to go in the big tank. <This genus members do MUCH better in groups...> I could easily partition the quarantine tank (20 long) and intro them at the same time to the main tank. Is he likely to settle in with my collection or is he better left at LiveAquaria for somebody else? Thanks Rich <In this sized volume, with the fish species you list, this damsel should do fine. Chrysiptera spp. can be a bit nippy, bully-ish for their small size, but if there's room... as it appears here there is... Bob Fenner>

Damsel Fish, Chrysiptera, Amphiprion, gen. comp.  7/30/07 Hi <Hello> I am writing to ask about my damsel fish, I recently started using a different fish store after the old one was not very helpful and to be honest not too good. I lost the first set of clowns I put in so I let the tank cycle longer ,added a few new bits it did not have like extra power heads etc. I went to the store to get new pair of clowns but I also wanted some think <something> different, although the old fish store had said not to get damsels because of aggression, the new one recommend a yellow tail which they had in their tanks and recommended it as a hardy fish which was less aggressive than the others. <They are a little less aggressive, but can still be troublesome to timid fish.> He was fine at first but then he started to bully the clowns at first to the point they would not eat, but now they are fine, and have been in the tank for around 5 weeks now and eating normal. But he is still being very territorial doing the normal territorial things -rubbing up against them, charging at them, pushing them back when they swim else where. <Normal behavior for these guys.> The tank is not a large one, it's around 27 gallons so I'm limited on what I can put in. I'm getting a yellow goby in the next week or so but my question is will the damsel fish calm down when there are more fish added and realise that its not just his tank or will he be the same to all fish and keeping all the swimming room to him self? <His behavior shouldn't change.> He has no main territory apart from behind one rock where he sleeps. And my second question is my clownfish front stripe sort of looks cracked on top I've seen this on other clowns before I was wondering if it was just a normal thing or if their was something wrong? <Normal. As to the damsel, I'd be returning it. I'm not fond of having damsels in a community system for the same reasons you state. James (Salty Dog)> Hope u can help

Yellowtail Damselfish... solitaire, and Centropyge in a 35...  7/8/07 Hello WWM Crew! I have a 35 gallon tank consisting of 20 pounds of LR, one yellowtail Damselfish and one Ocellaris Clownfish. About 2 weeks ago I added a Coral Beauty. <Needs more room than this by at least twice> The Coral Beauty has had no problems eating or interacting with the other fish. Today when I feed my fish, I noticed the Yellowtail Damsel wasn't eating. As I watched the Damsel, I noticed part of his lip is losing color. Any suggestions of what I should do to keep this fish healthy and eating? Thanks, Ryan. <Perhaps some sort of negative interaction going on here... And the Damsel is likely a social species of the genus Chrysiptera... live in groups... Please... read re these species needs (and all future purchases) on WWM... Systems, Compatibility especially. You need a larger system, more members... Bob Fenner> Yellow Tailed Damsel Harassing Royal Gramma 4/23/07 Hi Bob, I love your website. <Hello, Chris here today.>  It has been extremely useful.  Thank you. <Welcome from all of us.> I am a long time reader with a first time question.  I have read the FAQ's regarding my problem but I still felt compelled to ask.  I have a 40 gallon breeder reef tank.  It has housed a tomato clown and yellow tailed damsel together for 1 year or so.  I added a Royal Gramma a few days ago and he was immediately harassed by the damsel.  The Gramma has been hiding behind a powerhead nursing a lightly torn up tail fin.  He eats the frozen mysis shrimp when they pass within a few inches of his powerhead at feeding time, but I have not seen him venture out further than this.   Will he and the damsel ever get along? <Maybe, maybe not.> A gentleman asked the same question in the FAQ's, only he had a 75 gallon tank.  You told him that everything ought to settle down, and that he could "Leave all in" with a tank of that size.  So now I am wondering, what about a 40 gallon tank?  Otherwise is there anything I could do to ameliorate the situation?  Thank you so much, Tom <I would give it a couple weeks to a month and see if they can adjust to each other.  This is dependent on the Gramma continuing to eat of course.  If this stops he will have to be removed.  Otherwise you could remove the damsel for a couple of weeks and allow the Gramma to establish himself.  This helps sometimes in situations like this.  If none of these work then the two fish will just need to be permanently separated.> <Chris>

Damsel/tank (small) (skimmer) question  3/13/07 Good day to all the staff of this wonderful website! I've read this site and its archives for the past 3 weeks and its been very helpful, got a couple of questions though. 1. is it true that yellow-tailed damsels lose their "yellowtail" color when they mature? <Mmm, not really... actually intensifies under "ideal" conditions... good water quality, nutrition, social factors...> how long (is it months or years?) does a damsel of this kind mature?    <Likely just several months... You can look on fishbase.org... and read their Cartesian graphs re such...>   2. my second question is, i have a 20 gallon with 2 yellow tail damsels and 1 clown <... too crowded... not healthy, sustainable> with about 15lbs of live rock, everything is fine and i don't plan on adding anything more, do i still need a skimmer? thanks in advance! <I would have, use one, yes. See WWM re... Bob Fenner>

Chrysiptera taupou behavior   1/3/07 Hello Crew, <'Allo, Bruce! Graham with you.> I'm new to the marine hobby and have started to stock a 29G that was an established FOWLR tank owned by another person. I have 40 lb.s +- of LR and plenty of hiding spots. <Not a very big system. Keep in mind that water is displaced by the hiding spots. Your 29g can quickly become a 18gal with 40lbs or LR and substrate.> The first fish was a maroon clown about 1.5" long, followed by a six-line wrasse about 2" long, and last was what I have identified as a Chrysiptera Taupou; Village Belle, Fiji Blue Devil, etc. <Again, this is a small system, probably too small for the damsel & clown.> I believe the LFS called it a red tailed wrasse, <Hmm...> but it perfectly resembles the subject fish in my Atlas. All fish were added within a 5-day period. The damsel initially showed some aggression to the wrasse and clown, but after two days things appeared to settle down, although the damsel was always first at the buffet line. <I assume that the damsel was not the last?> Two more days go by and the damsel has apparently terrified the clown as it spends most of the time in the left top corner near the sump return. <It sounds very characteristic of damsels of the Chrysiptera designation. "Devil" should have been a marker for you, but with the LFS's moniker of Red-tailed Wrasse, you can be forgiven.> Today I came home from work and the wrasse is dead, and the damsel is doing what appears to be fanning sand on top of the wrasse with it's tail. Could the damsel have killed the wrasse? <Oh, no. Yes, the damsel may have killed the wrasse, but without knowing how long this system has been up and running, nor what your water conditions are, I might add that the Six-line (Pseudocheilinus hexataenia) would be the first to go with poor water conditions.> Does the damsel need to go back to the LFS? <In all likelihood, yes. You don't have much room, and even less room for stress triggered by aggression.> It is very pretty, and everything I read says the clown should be a good match for it. <We as hobbyists strive to balance "pretty" fishes with proper selection of these same specimens with regard to their tankmates and life-support. I think you will find in short order that, although the Maroon clown (Premnas biaculeatus) is a tough customer when it has been established in it's environment and feels secure, it is obviously stressed and the devil is seemingly taking advantage. (Maroons *are* usually pretty mean to other clowns, though)> The next addition was going to be a yellow tang, followed by corals and clams (I've read that the six-line wrasse is necessary for the clams) and a move into a 50G within another year or so. I thought I had a good mix of fish. What do you think? <I think you need to slow down a bit and do some extensive reading. Nothing bad can come of your waiting, but many bad things can and likely will result from hasty decisions. least welcome would be your discouragement from the hobby after failure.> Thanks, Bruce <You're very welcome Bruce. -Graham T.>

Yellow Tail Damsel  11/21/06 Hello Crew: I wanted to run a reef stocking question by you.  It is a 55 Gallon work in progress and I am trying to finish the fish list.  I currently have 2 Percula Clown's, 2  Cardinals, and a Yellow Watchman Goby.  I would really like to add either one or a small group of Yellow Tail Damsels.  Would this be a problem for the Cardinals?   <Likely not them... but the Perculas may negatively interact with these other Damsels in time> If not how many would you add?  I really appreciate any information you can share. Thank you very much for everything you do. <Perhaps three... of small size. Bob Fenner>

Adding a Yellow Tail Damsel to a peaceful 55g  11/20/06 Hello Crew: < Greetings, Emerson with you today. > I wanted to run a reef stocking question by you. < No problemo > It is a 55 Gallon work in progress and I am trying to finish the fish list.  I currently have 2 Percula Clown's, 2  Cardinals, and a Yellow Watchman Goby.  I would really like to add either one or a small group of Yellow Tail Damsels. < One would most likely be fine. > Would this be a problem for the Cardinals? < I have seen cardinals and damsels housed in a 55g with no ill effects. We are talking about damsels though, and these as with all fish can vary greatly in temperament from one to the next. > If not how many would you add? < I will venture to say that you could add a couple of damsels to your tank, given that they are of different species. A Yellow tail and a Talbot's would probably do fine given enough rock to claim as their own. If it were my tank I would add one damsel and enjoy the show :) > I really appreciate any information you can share. Thank you very much for everything you do. < You are very welcome and I hope the best for you and your tank! >

Yellowtail damsels in a 29? Not advised   9/27/06 Hi Bob. Great website. I just set up a 29gal. saltwater tank with 20 lbs. of live rocks. I only want Yellowtail Damsels in this tank. Because I know that they are very hardy and can be in groups. <Mmm... are feisty with each other though... particularly when/where crowded in a small volume...> My question is: How many Yellowtails can I put in my tank?   Thank you. <I would look for other livestock for this small system. Please start reading here: http://www.wetwebmedia.com/smmarsysstkgfaqs.htm and the linked files above. Bob Fenner>

How many blue devil damsels in a 55G tank?    8/13/06 And don't say zero. :) <Heeee heeeeee!> I know people dislike them, and I know why, but they're the reason I got into SW in the first place. For the last ten months I've had three in my 55G tank, along with a chocolate chip starfish (eight months), and a few small hermit crabs and shrimp. All is peaceful; the damsels do snipe at each other occasionally but it's not serious. I would like to get a few more. I do not plan to have any other kinds of fish in the tank - am I able to add more, and if so how many could my tank comfortably support? <Mmm, would have to define terms here... but three of the "standard species": http://www.wetwebmedia.com/chrysiptera.htm\ and the files linked above.> I will, of course, be quarantining them prior to their introduction to the main tank, and I intend to rearrange all rocks when they go in. Thanks! Heather <Could crowd a bunch more in... but they would eventually reduce their number to about this. Bob Fenner>

Compatibility/Marine/Blue Devil & Tang, Flame Angel compatibility   2/23/06 Hi Bob and Crew, <Hello Mandy.> You have a fantastic site and I'm really impressed with your generosity in giving your time, so firstly thank you! <You're welcome.> I have a 55G tank Current inhabitants: 1 yellow tang 1 flame angel 1 sixline wrasse 2 blue-green Chromis 1) I really love the Blue Devil Damsels (Chrysiptera cyanea) and am wondering if they will be compatible with my yellow tang and flame angel? I would like to add 1, 3 or 5. <The tang and angel could hold their own but I think the Chromis' would be picked on.> 2) Will I need to remove the Chromises and sixline - are they compatible with the Blue Devils? 3) Would the Yellow-Tail Blue Damsel (Chrysiptera parasema) be a better option? <Yes, much less aggressive than the Blue Devil and do not grow quite as large.> Previous research: I posted a thread on the forum and unfortunately didn't get a definitive answer: http://wetwebfotos.com/talk/thread.jsp?forum=2&thread=34311&tstart=0&trange=15 I also researched WWM: Damsel compatibility    http://www.wetwebmedia.com/damselcompfaqs.htm Chromis compatibility    http://www.wetwebmedia.com/chromcompfaqs.htm Damsels    http://www.wetwebmedia.com/damsels.htm Chrysiptera Damsels    http://www.wetwebmedia.com/chrysiptera.htm I am a long-time reader, first-time emailer, and would very much appreciate your professional input.

Orange tail damsel  - 1/6/06 Hello and Happy New Year, <Thank you and the same to you> I first wanted to say that your website is great and I really appreciate all the hard work you guys put into it. <Our thanks> I am actually returning to the hobby after a two year hiatus. I have a 24 gallon nanocube with about forty pounds of beautiful aquacultured Florida live rock that is teaming with life. I'm trying to keep something low maintenance, so will not be keeping corals, except those that came with the live rock, and sponges and macroalgae! Well my question goes to stocking this tank. It will mainly be an invertebrate tank with crabs and shrimp and feather dusters, but for a fish I think I've narrowed it down to a Orangetail blue damsel, Chrysiptera cyanea. I want to keep one male and 2-3 females if this is feasible in this size aquarium. I would also like to keep some sort of goby, possibly a red-head goby, or clown goby. Wondering if this selection will work, or if you have any other suggestions. <David, three of the damsels is all I would keep in this tank.  They do attain a length of three inches and as they age they become more aggressive, constantly defending their territory.  I don't believe the gobies would fair too well with them.  James (Salty Dog)> Thank you very much,<You're welcome> David

Frisky fishes  10/5/05 Hello, My question is about the 2 yellow tailed damsels I have. Apparently they turned into a mating pair after buying from the LFS. After about a month of being in the tank the female started laying eggs, about 4 or 5 broods now, and they keep getting fertilized and hatching, though I'm sure all the fry get eaten or sucked into filtration, and those who dodge that bullet probably starve, so my question is...are all these dying fry having any sort of effect on my tank parameters?  She lays new eggs about once a week, On advice from my LFS I tried lowering the water temp, but that didn't seem to discourage them from breeding, and I'm sure if I took out the fake plant she likes to lay them on, she would just lay them somewhere else, I would like to take a stab at breeding, but not with damsels, not worth most of the effort in the long run,  seeing as how they are only $3.99 at the LFS, and I have read that damsel fry are hard to raise because they are so small. but any words of wisdom to curb my "spunky" fishes desire would be greatly appreciated. Thank you. Jessica <No need to worry.  You have a deli in your tank.  Most if not all will be eaten as snacks providing some extra nourishment for your fish. Shouldn't have any effect on your water parameters, no more so than uneaten food in your tank.  James (Salty Dog)>

Orange tailed Damsel I have had an orange tailed damsel (Chrysiptera cyanea) for at least 5 years (no idea how old he was when I got him). He is in a 180 gal reef tank.  Over the past year or so he seems to have gone through a transformation of sorts, now all of his fins are orange (or have orange on them and his whole body is flecked with orange.  I attributed that to him going through some sort of super-male phase (do damsels do that). <Mmm, not as far as I'm aware... but this species does "color up" become more orange with age, growth> lately however there is a further development - his head is expanding in the area above and behind his eyes. This expansion appears to be symmetrical (left to right), but is to the point that the scales are raised.  He almost looks like some of the fancy goldfish with the growths on their head.  Behavior appears to be normal. Any idea what is going on here? <Well, damsels and many other fishes do get more "girthy" in the head region with time... but this may be pathological. Bob Fenner>

Damsel ID Crew: Can you help me identify this Damsel?  He looks like a couple of species, and I cannot "decide" which one it is.  I am thinking Chrysiptera hemicyanea, but maybe Pomacentrus auriventris or P. caeruleus?  I need more convincing.  If it is C. hemicyanea, does the nickname "Demoiselle" suggest it is dainty or gentle? <Just small... but this is a more than average easy-going damsel species> ("TONIGHT AT 11, A NEW DAMSEL SPECIES, THE 'DAINTY DAMSEL' WAS DISCOVERED!  IT IS YELLOW AND WEARS A LONG DRESS!")  Thanks, Rich. <Mmm, nice pic of a Chrysiptera hemicyanea. Pls see here: http://www.wetwebmedia.com/chrysiptera.htm Bob Fenner>

Re: Fiji damsel >Hi Marina (and crew of course) >>Good morning, Connie! >I read your response today to someone telling them about one of your fishes, a Fiji damsel.  I have checked all the suppliers on line that I know about and haven't found any info.  Could you tell me where you acquired this pretty fish??? >>Oh my, that would have been Bob's department, as I'd never seen the fish until I worked with him some ten years ago or so.  They came in a shipment he'd ordered, but I'm going to do a quick search and see what I can find.  Ok, so far I'm finding that the pink and yellow damsel I have been calling "Fiji" is something else entirely from what most others are calling "Fiji"!  O!  Lament the common names!  But I'm not finished yet.   >Thanks so much for your help, Marina.  Connie >>You're welcome, now let's see what I can find for you!  Here's something close, but it's not the same fish http://www.fishbase.org/Summary/SpeciesSummary.cfm?genusname=Neoglyphidodon&speciesname=nigroris >>Here's a pretty one, but not the one I was talking about...BOB!  LOL  http://www.fishbase.org/Summary/SpeciesSummary.cfm?genusname=Chrysiptera&speciesname=bleekeri >>This one demonstrates the posterior dorsal fin spot, but on the animal I'm thinking of it wasn't ringed, still, beautiful http://www.fishbase.org/Summary/SpeciesSummary.cfm?genusname=Pomacentrus&speciesname=vaiuli >> http://www.fishbase.org/Summary/SpeciesSummary.cfm?genusname=Chrysiptera&speciesname=rex >>Well, that's it for my search.  We'd have to ask Bob if he remembers this little fish at all, because I've now spent the better part of 45 minutes with no luck finding the exact fish I remember, nothing even *quite* close.  I am very sorry, too!  Marina
Re: Fiji damsel
>Dear Marina: Thanks for all your research - I really do appreciate it.  I liked two of them, the pink damsel and the Bleeker damsel.  Getting them will be really hard, as most dealers don't want to special order damsels, I have found. >>Correct.  But, I now have this bug up my butt, I really want to know what kind of damsel that was that we got in all those years ago!  I think it's time to head down to Discount Tropical and get a hold of old Tracy's bible!

Damsel in distress question? Hi There,  I just started up a 12G saltwater tank with 10 lbs. of live rock and two yellow-tail blue damsels <! this species needs a good ten, fifteen gallons per... in a larger system> (the tank was cycling without them for a month prior).  My question concerns one of the damsels as it stays in the bottom corner of the tank and every time it tries to venture out, the other damsel chases it back to the corner.  Yesterday it was hiding in the top corner of the tank and looked as though a goner, but I guess it was just sleeping.  Is he sick and the other damsel is just picking on him, and should I rearrange the rocks so they can redefine their territory?  Thanks a lot, Jon <There's not enough room for such redefinition. I would remove one of them pronto. Bob Fenner>

Fish Disease Hello to You: <Greetings to you!> I have attached 2 photos of my male Blue Devil Damsel (is that right?).   <I'm going out on a limb and saying that I think it's a female Chrysiptera cyanea (blue devil> He has some stuff on the base of the fin, and now on the edge of the same fin. He seems to be using that fin less than the "healthy" one kind of swimming in circles - HAHA - just kidding. <The two items mentioned above are what's concerning me. If he isn't using the fin something is wrong. Ich (Cryptocaryon) is spots that look like salt. Not likely in this case. Marine velvet (Amyloodinium) looks more like tufts of cotton or a covering of cotton. IMO this is what I think I see on your fish. I can't be positive from this distance. If she's been scratching or glancing against objects, this will give a clue that it may be a parasite> I needed a little laugh in this time of grief, as this is my first illness, and maybe death, <She isn't dead yet!> in these early months of the hobby. Any identification?   <I don't get too freaked out about small places on fins because they can have accidents from time to time that will make the fins have small places that become less than translucent. These places sometimes come from other fish taking a bite or normal damage while swimming around the tank. Having written this, frequently fins are the first place that parasites will attach and become visible: especially ich> I just moved him to QT: of course I have a couple of crabs & snails in QT at the moment.   <If he is infected, you are increasing the chances that the snails and crabs (while immune to the effects of ich or velvet) can be carriers of a disease> That limits treatment, right? <No copper with snails and crabs> I appreciate your help more than any LFS, because you don't take my money (CMA notwithstanding, but that was a steal anyway!) Thanks, Rich. <Check your CMA book for directions on giving treatments for Amyloodinium. Then check the website for the same. At least do a freshwater bath with formalin or Methylene blue (see CMA or WWM for directions) and possibly start a copper treatment. If you do copper you won't be able to put invertebrates in the QT any longer. Read and decide for yourself what will work best. Good luck! David Dowless>

Chrysiptera <<Greetings,>> Hi, I found your page by an accident (a nice accident) Please if you can I will appreciate if you can get me out of this doubt? I bought two damselfish, the first one I'm pretty confident that is a Chrysiptera cyanea, but the second one I'm not sure, because the name is the yellow tail damsel (and looks like), but when I was surfing the net and for my surprise, in different places I found the same photograph for both of these fishes: Chrysiptera hemicyanea and Chrysiptera parasema. There are 2 yellow tail damsels?? If there are, how can I know the differences? <<Well, Fishbase has the Chrysiptera hemicyanea as the Azure damsel, and the photo they have does not show a yellow tail. Here's their link: http://www.fishbase.org/Summary/SpeciesSummary.cfm?ID=6919&genusname=Chrysiptera &speciesname=hemicyanea And of course, the Chrysiptera parasema is the yellow-tail damsel as you identified: http://www.fishbase.org/Summary/SpeciesSummary.cfm?ID=12448&genusname=Chrysiptera &speciesname=parasema The pictures you saw on the Internet were likely mixed up.>> Thanks for your time Carlos D?z (Guatemala, Central America) <<Cheers, J -- >>

Feeding Tangs Thank you very much for your prompt answer, now I'm sure it is a Chrysiptera parasema. Another question...With the damsels I bought a Tang (Zebrasoma ). It attacked all the green hair algae. If he (or she) is still eating at that rate, my tank will be free of green hair algae in just a few days more... my question is: Then, what am I going to give him (or her) to eat? <Please look at the writings on WWM concerning Surgeonfishes. -Steven Pro>

Re: Yellowtail Damselfish I have a problem with both my damsels. One keeps attacking the other one. <Very typical with many species of Damselfishes... territorial generally. Sometimes keeping them in odd numbers lessens the damage to just one in "even number" settings. You might try adding another individual if there's room, placing more habitat (e.g. live rock)... otherwise it would be prudent to remove the one getting beaten> I would like to keep one of them, but would like to get another fish. Do you have any suggestions? I started my tank only 2 weeks ago. <Please read through the "Livestocking" sections on our site: WetWebMedia.com ... There is much "going back and forth" we'd have to go through to inform you. For instance, you provide little information on how large your system is, its make-up... All important factors in such determinations> Oh yeah, this might be a silly question, but is it dangerous if a fish mates with other species within the same genus? <Dangerous? No. Generally will not result in viable offspring. Bob Fenner> Thank you.

Yellowtail Damselfish Hi there. I was wondering if you could tell me how I can tell a male yellowtail damsel from a female yellowtail damsel?  <little dimorphism... no reliable sexing I know for the laymen> Is there any other type of damsel that would mate with the yellowtail? <hopefully not, but I suspect so (other species within the genus). Please don't encourage it. Anthony> Thank you. Cindy

Damsel in Distress Mr. Fenner: <<JasonC here, Bob is in the tropics somewhere... >> Thank you again for taking the time to answer questions. I have a 165g tank with 45lbs of live rock and 20lbs of red porous rock. Will continue to build up the rockscape as budget allows. I only have three Yellow Tailed Blue Damsels (Chrysiptera parasema) and one South Seas Devil (Chrysiptera taupou) in the entire tank. Have had these fish for 2 weeks and was using them to get the cycle going. The yellow tailed seemed to chase each other periodically but only for a brief spurt. My LFS thought that a 165 was large enough to allow these fish to each have space. <<the tank surely is, but the actual cover [rock work] is perhaps a little sparse for a tank of this size at the moment.>> However, after the water change two days ago the smallest yellow tailed, about 1 2" others 2", spends most of the light period behind the CPR overflow U section. It never did that before. <<most likely his first water change... >> Then when the lights turn to the blue only (to simulate dusk / dawn) it comes down and swims around. I feed these fish twice a day (flakes in am, brine shrimp in pm) and they gobble it all up. <<always a good sign>> Will this damsel thrive in this set up? <<the individual or the group?>> Do I need more hiding places? <<yes>> Should I feed more to possibly cut down on the other damsels chase spurts? <<probably wouldn't actually have the desired result - more energy to chase...>> Or should I try to take the fish out? <<more live rock will help. In a group of three like this, you end up with one being the low man on the totem-pole. More cover will help this, but most likely this one will always seem to be the most chased after, rock or not. Have kept three of these myself - sounds very familiar. Cheers, J -- >> Thank you again for your thoughts. Steve

Re: algae Thanks Bob. Good news. My son has received one of your books already ' the conscientious' etc. I guess the next will follow soon. By Christmas I should have them all. I will follow Your advise and keep You posted. I found out that I have a lot of friends on the islands that could supply me with live rock and live sand if necessary. They are all excited about my final setup. Is it a good idea to put ' Caulerpa ' or turtle grass in the tank? <Caulerpa spp. are excellent, Turtle Grass is actually not easy to keep... for it you really need a very large system... or even a separate sump for culture> I might get that myself. I will send You photos and keep You updated. It seems that I never run out of questions. Sorry. If You ever happen to come this way, make sure You contact me before hand. Tel/fax: 504 442- 2713  <Ah! Will do so my friend. Haven't been back to your part of the world for a few years.> The question about the 'Chrysiptera parasema ' is that it costs only about a third of an ocellaris!! But I don't want to start with a damsel that doesn't allow another fish in the tank afterwards! Always at your service. Bernd <This type of "yellow-tail blue demoiselle" is actually pretty easy going... mellow enough to go with most all: http://wetwebmedia.com/chrysiptera.htm Be chatting my friend. Bob Fenner>
