Stingrays, sel., reading    11/27/08
Hi, I was curious to know if you could help me idenfy these stingrays. I have a 300 gallon tank and would like to buy 2 of them. I think they coul either be CA stingray, Cortez stingray, or round stingray??? there in this video, here is the URL. Also could you tell me which would be the smallest of these. thanks--James calvetti

Re: Weird behavior from an Emperor Angel/General tank issues...  -08/27/08
Yes, I had slacked on my water changes when my RO/DI unit broke. I will resume my normal regiment.
<And regimen, about face!>
Ok, so it's time to upgrade tanks. I have had my eye on a Ray of some type; maybe the Cali Round one.
<Uhh, time to read... this is a cool/coldwater species...>
SO if I upgrade tanks, can I go with a 72X24X25 or do I have to go more with a 60x36x27.
The population I am envisioning would include my current blue/yellow tangs, Emperor(If he makes it), and bird wrasse....
Thanks so much for your help!

Clearnose Skate, sel.  8/3/07
Hello WetWebMedia Crew!
<Hi>
I have a few questions concerning a species of skate called a "Clearnose Skate".
Before I start, I must point out; I am completely unable to care for any Batoid species at this point in time (freshwater or saltwater), and I will not be until I graduate from college, which is a long time away. A website called "Sharksupply.com" is offering the Clearnose Skate at 5" in size for a mere $50, which sounds fantastic since that's the cheapest ray I've ever heard of. Based on some sketchy research I found that this skate gets just a little over 2 ft in length at most (correct me if I am wrong). Judging from that this sounds like a great "first ray" species. I would just like to know how big a tank would be required for one, maybe 2 individuals, as well as preferred temperature and environment. Any guidelines would be appreciated. Also, would this skate be compatible with other Batoid species like Guitarfish? Or do skates prefer only hanging out with other skates? I've always seen in public aquariums eagle rays, stingrays, and guitarfish all hanging out together, but no skates. Is there a particular reason for this? Finally, what is the general behavior of this skate? I'm not so sure if I would care to drop a few grand to set up for a fish that does nothing but sit buried in the mud all day. Does this species spend all of it's time sitting around lazily, or is it at least mildly active and entertaining?
<I'd read here and linked files above for information on this. http://www.wetwebmedia.com/rays.htm?
Thank you for your time.
<You're welcome. James (Salty Dog)>

Mmm... Porcupine Puffer fdg., Keeping a Batoid  2/18/07
Hello Gentlemen (and Ladies),
<Heeee! Oh, you're not joking... Okay>
  I have 10 years as a paid aquarist and have volunteered at several public aquariums across the country.  I would like to think that I have a pretty good amount of experience with marine fish and invertebrates, but I do have a few quick questions that I was hoping you could answer for me.
<Will try>
   I have a 3 inch porcupine puffer (Diodon holocanthus) in my large fish only tank with live rock.  I have had him for about 3 weeks and thus far I have not been able to get him to accept frozen or freeze dried foods.
<Mmm, does happen... as you're likely aware... Puffers of all sorts, sizes... go on feeding strikes often when moved... sometimes for no apparent "reason">
I have fed him live feeder guppies once per week, and he has managed to catch and eat a few.  He is too slow to catch more than one or two per feeding, and my Humu Humu trigger will no doubt eat any live Ghost shrimp or clams that I offer before the puffer can make his move.  
<The presence of this trigger may be a large part of the reason for not feeding here...>
Any thoughts as to what I can do to get him to begin accepting thawed frozen food or freeze dried krill/plankton?  
<An open shellfish... and either removal of the Balistid, or moving the puffer to better psychological setting>
  My second question involves aquarium stingrays.  I am setting up a saltwater system for a friend, and he wants to keep a stingray.  I have informed him that they are by no means easy to keep, but he wants one nonetheless.  I am installing a deep, sugar-fine sand bed and minimal rockwork, to maximize space.  The tank is 240 gallons with a sizeable footprint.  There won't be any triggers or puffers in the tank, and the ray would be the last animal added.  Other than adding a few live crustaceans to the sand bed to aid in feeding (and thereby acclimation) is there anything else we can do to increase our chances of success?
<Mmm... be careful when picking out species, a specimen...>
We are looking at both the Blue Spotted Ray and the California Spotted Ray.  
<Both exceedingly poor choices historically... The California will/would require a chiller... keeping only other cool-water species...>
  Thank you for your time.  I very much enjoyed reading my copy of "Reef Invertebrates", and I love the work that you guys do.
Best regards,
Danny Riskam

I have a California round and a blue dot sting ray in a 150 gallon  2/18/07
Hi I have a quick question I have a California round and a blue dot sting ray in a 150 gallon.
<Mmm, one's tropical, the other sub-tropical... see WWM, Fishbase.org re these species... incompatible>
They are on their way to a 300 gal. but when I started the tank I put live rock bio Spira etc to get the good stuff going now I have pulled everything out so they have plenty of room. (this was 5 months ago w/ nothing in the tank they've been fine) Question is how does good bacteria get in there now?
<Mmm, with transference of water, substrate, filter media... even the air in time>
Will they be ok in there w/o anything? Do they need anything else.?
Michelle
<Mmm... no way to tell, as you haven't related what "they have" presently... Please skim over WWM re Batoids in captivity... http://www.wetwebmedia.com/marine/fishes/index.htm

Urolophus halleri (Round Ray), not eating, not tropical  9/18/06
Hey Crew,
  We got a Cali ray that came in to our store last week on Thursday. The ray hasn't eaten yet. It seems like he doesn't want to eat. We have tried frozen squid, krill, gulf shrimp, and live ghost shrimp. None of them have worked. She swims all day and all night and rest for a little bit. Should the ray be eating by now? I've looked at some of the articles on your site and nothing helped. We have been hand feeding and stick feeding.
  Thanks,
  Ben
<... is this fish in "hot water?"... See here: http://fishbase.sinica.edu.tw/Summary/speciesSummary.php?ID=2580&genusname=Urobatis&speciesname=halleri
Subtropical... likely needs to just be placed in cool/cold water and allowed to acclimate. Bob Fenner>

Re: Urolophus Halleri (Round Ray)... another cold/cool water animal misplaced  9/18/06
Temp is at 78 and going down slowly. Yesterday the water was at 80 and the ray never really rested. Today he has been in the sand for almost the whole day. We'll try feeding her again tonight.

Stingray mega system  - 09/07/06
<Hey Dan you are in luck, I've kept some stingrays and have some experiences to share with you.>  After seeing all the great advice on your site, I thought I might tap your brains as well with a few questions on my mega large, stingray system.  I have been in the saltwater hobby for almost 10 years, currently running 3 other tanks, so I know the basics, but this is my first go-round with stingrays.  After seeing something at a LFS, I decided to build my own "lagoon".  The display tank (not counting the filter) is Approx. 1,200 gallons, in the lower level of my house, with a pond liner.  It is roughly 8 foot by 8 foot and 2.5 feet deep.  It is filled with a 1-2 inch
deep sand bed made of sugar sized Aragamax, and has a small (30-40 lbs.) pile of live rock in the center.  It is now time to stock the system.  My questions are these:
-Should I be worried about the pond liner (40 mil typical outdoor pond liner) being punctured by the stingrays' spines/barbs when they swim around?  <Based on my experiences no. Stingrays aren't usually aggressive unless they are provoked. Meaning they don't go around with their rays ready to puncture all the time.>
-I would like to house a variety of stingrays in there, and after doing the research it seems that, in a system this size, I would be able to put 3-5 rays in there total.  Could I maybe do a Bluespot or two, maybe a California round or two as well?  I know Bluespots are difficult to keep, but due to the size of my system, I think many of the problems most folks encounter will be overcome. <My friend kept Bluespots without any troubles. I believe that the major thing with them is that they need to be shipped in healthy and from a reputable dealer. But I don't think you are going to be able to keep Bluespots and California species together because Bluespots need a warmer water tank than the California rays.>
-Finally, in a system this size, do you see any problem with adding a big fish or two (like a grouper, something that will not generally pick at rays)?  <You possibly could add some fish but let me warn you RAYS ARE HUNGRY and will eat and or attack lots and lots of other fish and devour them pretty quickly.  Especially, in my experience, the blue dots.>
Thanks in advance for the advice, and the past advice to others cautioning them to treat these animals for what they are: living creatures who need to be cared for, not merely a "thing" to be had. <If it was me I would plan on trying to keep a pair of stingrays and I would put any other fish you planned on keeping in first and letting them get establish. Let the system stabilize and get settled as well. Realize that stingrays like other predatory fish are going to produce a tremendous amount of waste and that you'll need to plan your filtration to accommodate them. Realize that most stingrays are going to be larger animals and that's going to require special equipment for changing things in the tank. Realize that you aren't going to want to reach your hand in the tank for many reasons. Figure out other options for cleaning.  Bless Steve Irwin's soul, but these animals do have the potential to kill so keep that in mind as you choose what to do in this system.  Hope this helps and if you have any more questions just let me know. Good luck, MacL>

Stingray laws  - 09/03/06
Do you know in which states in the U.S. it is legal to own a stingray in your home aquarium?
<Mmm, freshwater or marine? Only presently aware of the former (Potamotrygonids) being restricted in our State of California>
Everyone else I ask just says "don't tell anyone you have one" but I don't want to do that. I want to know. We just got an aquarium, 110 gallons.
<Too small for marine Batoids...>
We haven't put anything in it yet, the stand is still being built so we're trying to weigh our options and we love stingrays. We are in the military so we move every few years, even if it isn't legal in this state, it may be legal in our next.
<Contact the State(s) "Fish & Game"... they will know. Bob Fenner>

Sale of Urobatis jamaicensis  8/8/06
Hello Bob, I saw the aquaria trade article you wrote on webmedia.com and was wondering if you have an idea how to come across the number of stingrays,
particularly Urobatis jamaicensis that are sold annually, and for how much. (Any info would be helpful) Please contact me with any suggestions you might
have to acquire this information.  Thank you in advance.
Cheers, Dan Fahy
<Mmm, likely the best place to look is through a roster/listing of saltwater collectors/dealers that are members of the FTFFA... Please see here: http://www.ftffa.com/
There are likely quite a few fisherfolk who could supply this species out of the TWA as well... Good fishing! Bob Fenner>

Sharks and rays ... incomp.  - 05/20/2006
Good day folks.
<Noam>
I have read through hours of your postings and although the information is invaluable I have not found the answers I seek.
<Good>
I am currently cycling a 250 gal tank. My goal is to house one bamboo shark, and one ray. I know the California ray is the right size and temperament however it requires colder water temps compared to the Shark.
<Yes>
Can you please suggest a Ray that is both small in size, and has the same water requirements as the Bamboo shark.
Thanks from Chicago.
<There are tropical species... not often offered in the trade... and I don't encourage mixing these groups... too much "dust", activity from the Ray... Bob Fenner>

Urobatis jamaicensis in captivity    4/25/06
Hello my name is Riley I have read a lot of  information on stingrays. I currently have a P. reticulatus, but I'm also  interested in marine rays I have
researched and found that  Urobatis jamaicensis is the most suitable for life in an  aquarium. I searched your site and found no information regarding this
ray other  than ("Urobatis jamaicensis (Cuvier 1816), the Yellow Stingray. Western  Atlantic; North Carolina to Venezuela. To thirty inches wide. Aquarium and
Cozumel photos.")  I would like to know the basics and the requirements of   this beautiful animal.
<Mmm... you should peruse the article, FAQs on Batoid fishes...>
Such as tank size,
<Hundreds to thousands of gallons... at least twice the width of the intended maximum size, thrice the length. Height not very important functionally>>
eating habits etc. I would also like to  know how to go about purchasing this ray, what sites or sources carry it.
Also  what are appropriate tanks mates?  Your help is most  appreciated.
Thank you for your time!

Sting Ray Care  10/4/05
Hi,
<Hello, Adam with you tonight.>
I Love stingrays and have had very good luck with California Rays (Urobatis Halleri) <Very neat temperate species.> and extremely bad luck with a (Taeniura lymna) Bluespot Ribbontail Ray throughout my aquatic career.  <This is not surprising at all.  Often they die within the first week or two of captive life and rarely accept food.  Even when they occasionally accept food they seem to go on hunger strikes at times and often never resume feeding.  Very rare that this animal is kept successfully long term. This one is best left in the ocean.>  I have been lucky enough to obtain a baby Bali Bluespotted Stingray (Dasyatis Kuhlii) which is currently residing in my 50 gallon quarantine tank. <Ahh yes this “look alike” species is much hardier. Generally they are easily coaxed into taking frozen fare such as fresh market fish, squid, krill, any meats of a marine origin really.  You should have a fine layer of sand on the bottom of the tank, at least 3” in which t can bury itself when threatened.  Coarse sand will cause irritation to its smooth skin, which can lead to bacterial infections and even death.  You’ll also (eventually) need a tank of at least 300 gallons with lots of surface area and minimal rockwork.  Keep in mind that as with all elasmobranchs this species is sensitive to stray electrical voltages, heavy metals, and high nitrate levels.>  I have tried to search both WetWebMedia and the web and have not found much information on care about this stingray. Please help me learn to provide the best possible atmosphere for this animal.
<I also will take this opportunity to plug Scott Michael’s book “Aquarium Sharks and Rays.” It is filled with tons of good general information. However I will say that I disagree with many of the listed tank sizes for some species. I believe all sharks and rays should be treated to X-large spacious tanks (not closets) or left in the ocean.>

Ray on the dailies - Dasyatis sabina? 8/25/05
Hey, Bob!
Got a question for yah....
On the dailies I saw the fellah with the "ray"/skate,
and the link to his prior email which included an
image of the animal.
Is it possible that this is Dasyatis sabina, the
"Atlantic stingray"?
<No hon... Look at the rostral area... this is a rajid, a skate>
I have read some articles about
this species being found in purely freshwater
conditions, reproducing and living out their entire
lives....  I certainly don't know if this is true, or
even remotely accurate.  Here's one of the articles
I've read, which includes an image that very closely
resembles our querier's animal:
http://www.ecofloridamag.com/archived/stingrays.htm .
Somewhere along my travels across the web, I have also
read that the animals collected and sold as
"freshwater" in the hobby are almost always collected
in brackish or marine conditions, and few survive long
at all.  There goes my dream of legal freshwater rays
in CA.  Sigh.  Thoughts?
-Sabrina
<Few and dismal. BobF>

Re: Ray on the dailies - Dasyatis sabina?  8/26/05
Is it possible that this is Dasyatis sabina, the
"Atlantic stingray"?
<No hon... Look at the rostral area... this is a
rajid, a skate>
To be quite honest, I have absolutely no clue what, of
the rostral area, can be seen to differentiate a skate
from a ray....
<Ahh, sorry re... the "nose" or region just ahead of the eyes let's say...
is elongated, flattened... like a... skate! in Skates, family Rajidae...
Also the thorny dorsal spines are indicative of the family... distinguish it
from the many Ray families of Batoids>
  My apologies, in any case.  This whole
mess (and so very many others that we see every day in
WWM questions) certainly drives home the need for
emphasizing one's responsibility to research PRIOR to
purchase - I'd like to put something about this in the
book, perhaps as a section of its own, under
Introducing Fish....  or in the section on
compatibility....  or maybe preceding the fish
profiles.  What do you think?
<An excellent (consistent) idea, plan>
In any case, I think
I'll type something up tonight, if not for the book,
then for posting on WWM, perhaps.  Shall I send it
your way for editing/adding-on, if you wish?
Thanks,
-Sabrina
<If you'd like... I am accumulating our notes, articles... on folders on my
active desktops... BobF>

I recently sent you a question about stingrays.
Since writing I have done some more web based research and have found that they are not a species suitable for aquariums. I suppose you just take for granted that if a fish is on sale in a shop it is suitable for an aquarium. Unfortunately that is not the case.
<You are right on all accounts>
I totally agree with your stand point and they should not be imported.
<Ah, good to have company>
I would urge people not to support the importation of these fish.
<Good>
I have had mine for quite a while and everything was great. I think it is probably too late for the female now, but as the male is active, alert, eating and importantly growing I hope he is going to be okay.
<Me too>
He is in a 150 (imperial) gallon tank with sand, rock work and a cleaner shrimp. He seems okay. Fingers crossed...............
<Mine as well. Be chatting my friend. Bob Fenner>

Ray recommendation?
Bob,
I'd like to get a small ray, but I've seen how much trouble many of the
species can be, especially when they're inappropriately caught from the
wild. What would you recommend for a beginner? (To rays, not to keeping
fish in general.) 
<Please read here: http://www.wetwebmedia.com/rays.htm and the cartilaginous fishes articles and FAQs files linked beyond>
I'd like something small (for a ray), that's not likely
to die on me in a month or two. I will be buying a new aquarium specially
for it, so I'd also appreciate advice on an appropriate corresponding size.
(At this point I'm in the research stage, and I'm going to get a copy of
Scott Michael's new aquarium shark and ray book, now that it's available.)
<Yes... very worthwhile. Bob Fenner>
Thanks much,
Jen

Please reply soon!! (stingrays in IL)
I recently emailed you and thought of a new question. Do you know if stingrays are legal in IL if not do you know of a sight where I can find out?
Thanks again,
Timothy
<Marine Stingrays are not dis-allowed in any U.S. state that I'm aware. Freshwater ones are illegal in some (like California). Please direct your query to the State's Fish and Game agency. These can be found by searching in the Yellow Pages... or on-line via State listings/directories. Bob Fenner>

Blue spotted ray (larger questions of knowledge, morality)
Why would the store sell something that would die??
<Perhaps they're ignorant of the species historically low aquarium survival. Maybe to "make money"...>
don't you think you're pushing the dying fact a little to far. 
<Mmm, no. Put yourself in my/our place/s. Having been in the trade for decades, seen, had many of this (and other notorious species) die so easily, it seems only realistic to warn others of their "chances"... perhaps spare a few specimens untimely loss. What would you do?
Perhaps a romp through the various marine hobbyist listservs, asking for input of how others have fared would convince you?

- Captive Electric Rays -
Dear WetWebCrew,
<Greetings, JasonC here...>
Hate to be such a bother, but you guys are by far the best source of information I have come across. Just think of me as your unskilled apprentice, always curious. My friend just bought an electric ray to put in his 300 gallon tank. <Ohh nooo... please tell me you are joking.> He's had it set up for quite a while and is running adequate filtration and the water quality is fine and stable. We tried to ask the guy at the pet store some questions, but he didn't seem to really now anything. First off, is there any supplements he should use to better prepare the ray for aquarium life? <None... please consider trying to get this ray back in the sea.> We've already used "Cycle" to help ease the transition. <Cycle isn't made for such things.> I've heard iodine is good, or any other essential vitamins/nutrients? Second, what should be done properly regulate its sleep cycle? Right now, the lights are coming on at 10 am, and are going off at 11pm. <Should be fine.> It was my understanding that rays and sharks are nocturnal so we don't want to mess up anything having to do with his natural rhythms. <Not always, but often their food is nocturnal so...> Also, we tried feeding it both live ghost shrimp and skewered squid, neither of which it was interested in. Is this just because its still getting used to its new home? <It could also be because most all electric rays are not tropical fish and need to be in a chilled tank.> How often should he be fed, I've read twice a week, no more, no less. What is the best method of feeding it? Any other important info you could add would be greatly appreciated,
Sincerely,
Bob Benson--
<Bob, there just aren't enough ways for me to voice my disappointment. These rays are absolutely inappropriate for anything but the largest public aquariums, and for your friend to have purchased and placed it without knowing the care requirements in advance has likely sealed its fate. Please start by picking up a copy of Scott Michael's book, Aquarium Sharks and Rays - detailed care requirements are contained within. But let me quickly quote his book from the section Captive Care: "Unfortunately, due to their selective food habits, electric rays do not fare well in captivity. They feed primarily on annelid worms, both in the wild and in captivity, so unless you have access to a ready supply of these invertebrates, your chances of keeping an electric ray alive are slim." Sorry to be the bearer of bad news. Consider poking your friend to do the research FIRST.
Sincerely, J -- >

What species of stingray will live in a 75g tank?
None in my opinion... please read here

Some dasyatids... in Puerto Rico
Robert,
I am a graduate student in Puerto Rico in Fisheries Biology and I found your site while searching for species information on freshwater stingrays. The reason I am writing to you is because you made a statement on your website "None are currently utilized in the aquarium interest as far as I'm aware" and I wanted to let you know that I have just recently seen Dasyatidae in an aquarium for sale in a local mall.
<Mmm, there are a few dasyatids that are freshwater and brackish... and a few of the Amazonian freshwater rays (family Potamotrygonidae) are used in the hobby>
Now, I was perplexed by this because I do not know of this species being in freshwaters here in Puerto Rico. I just thought I would let you know that they are in fact now being sold in the aquaria market.
Cheers,
Kimberly
<Thank you for this. You may be able to identify this to species using fishbase.org (with the country search). Bob Fenner>

Good vs. Bad Blue-dot Stingray Species- what's the diff?  
Dear Bob,
<Anthony Calfo in his stead, my friend>
We've been wondering about blue spotted stingrays and were wondering if they are reef compatible
<not really. Even if your definition of reef-safe excludes their crustacean (shrimp/crab) diet... you still have to contend with their need for large spacious sand flats. A rockscape is a recipe for disaster with skates and rays (causing abrasions and perhaps leading to their demise) in the confines of captivity>
and also what size tank you would recommend for keeping one.
<200 gallons bare minimum... and more importantly, the most common species in the trade- Taeniura lymna, is staggeringly difficult to even keep alive (truly for experts and public aquaria only). If you must have a blue spotted ray, please seek the hardier Dasyatis kuhlii... less blue spots but much more likely to survive (small and adaptable). Scott Michael's "Sharks and Rays" is a must have book for you before you proceed too, mate>
Look forward to hearing from you soon. Many thanks in advance,
Martin & Lynsey
<with kind regards, Anthony>

Wanted: sting ray
to who may concern i recently have a 150 gallon salt water fish tank. I have a banded cat shark maybe about a foot long

You can call him Ray, he's new and not tropical, but hungry
Hi:
    I just got a California ray yesterday. It's quite small (the disk size is about 3 inches). The fish looks fine and has been stay at the sand bed. However, it does not move much unless my cleaner wrasse is bothering him. I am wondering how should I feed it?
I tried swing a piece of squid/shrimp in front of it, buried the meat underneath the sand near him. He just wouldn't eat. I think later I will get a turkey baster to shoot some brine shrimp in front of him to see if that works. Please give me some suggestion, thanks!
regards,
Howard
<Some suggestion? Likely to return the Ray whence you got it. Do you have a chiller on this system? This is not a tropical fish... it might not be eating simply because it is too warm. A cleaner wrasse? Please take the time to read through (use the marine index or the Google search tool at the bottom of the homepage) of our root web: http://www.wetwebmedia.com/

A Ray Of Hope?
Hi,
<Hi there. Scott F. here with you today>
I have just acquired a Taeniura lymna.  He is about 6-7" and was at the LFS for  only 4 days before bringing him here.  I place him in a 7" (220 gal) with mostly angels as tankmates.
<Yikes! Please be sure to quarantine all new arrivals for a minimum of three weeks before placing them in the display tank...Better for everyone...>  
I have looked everywhere and cannot find much info on these guys.  Even on your site, there really isn't much.  I've also heard that Bob has one of these beautiful creature's??
<I don't believe that he does have one...It's one of the worst of a pretty bad family of fishes to keep in captive systems. I don't like to sound negative, but I think that, despite your good intentions, you purchased a fish that really should not be kept in captivity. These fishes almost always starve to death for lack of available food sources in captive situations. They need a huge sand bed area, filled with infaunal life. If you can get this fish to eat prepared foods (like Mysis, frozen Cyclop-Eeze, or the like would be among the better choices), it will still have a very difficult time adapting to captive life...Sure, you might have the one in a million that does, but I'm afraid the odds are not in your favor.>
Do you know what he feeds his? how he feeds it, temp he keeps it at etc.  Also, my French is a little nippy with it...is this a big problem?? Can the ray defend himself? Or is this too stressful?
<Well, the added challenge of a nippy tankmate is really reinforcing the odds of failure, I'm afraid. At best, he fish may hang in for a while, but if you are going to have any chance at all, I'd recommend a tank of his own...>
Thank you so much  I for one have really truly appreciated all the help I've received from you guys.  My French would not be alive today if it weren't for you!!  Hopefully now you can help me with Raymond! Thanks again, Lynn
<Well, Lynn- I'm afraid that we cannot be of too much help here. Regretfully, retailers continue to stock these beautiful, but non-viable (for aquarium use) animals. The best thing that we can do for them is to vote with our wallets, and not buy them. Once there is no market for such animals, there will be no reason to import them. I know that you meant well, and I encourage you to do your best with this animal, but please read up and know the odds ahead of time when you decide to purchase ANY animal, especially one with such a difficult reputation. Do your best...Good luck! Regards, Scott F.>

A Ray Of Hope? (Pt. 2)
Thank you,  just wanted to let you know that I returned the ray the next day.  He was looking stressed to me, and what little info I found... encouraged me to return him.  After getting your opinion I am glad I did so.  I'll not make this mistake again.
Thanks again
Lynn
<Well, Lynn- I'm glad that you were able to get him back to the dealer. I can only hope that they can find this fish a more suitable home (perhaps a public aquarium?). Despite this unfortunate experience, I think that your compassion and enthusiasm will serve you well in the future...Don't be discouraged...Keep learning and growing in the hobby, and share with others! Good luck! Regards, Scott F>

California rays in a commercial aquarium environment
I am currently looking at buying a commercial aquarium/museum here on the Pacific Northwest (U.S.) coast. The owners previously had two seals - full grown- in a very large "pool" - the dimensions would be close to 20ft long - 8 ft wide made of concrete.
<A small/dismal world for Phocaena or Zalophus...>
I am not considering reintroducing seals but filling the tank with gravel and then sand (the proper sand per your web info I have read) and putting in a few pacific water rays in there. Something that the visitors could interact with (pet and possibly feed). The water is pumped directly from the ocean, into a sand filter and then into the 19 tanks and the seal tank and then pumped back into the ocean - so the temperature of the water is that of the local waters. My questions would be as follows: What type of ray is it that one of your writers had said was a very social ray?
<... maybe Myliobatis... all rays in this application take some acclimation to these circumstances...>
Also, if we didn't debarb them and just let them be on display (no petting/feeding) would it be ok to put them into the ocean in the winter if we shut the aquarium
down- and then repurchase some in the spring?
<Should be, yes>
Or are they hardy enough that we might be able to work out a "loaner" program with one of the big aquariums on the west coast (Long Beach/Monterey/Sea World) and ship them??
<You could ask, look into this, but I strongly suspect that the respective costs of shipping the animals, versus buying locally (likely through fishers) will be prohibitive>
Any input, even if the question wasn't asked, would be helpful. This business venture is more of a career change and I would like to be informed as much as possible if this could be an attraction vs. me thinking it could be.
Thank you in advance... and thank you for all the info on wetwebmedia. It has been very helpful.

Stingray (Dasyatis kuhlii)
Hi,
I was wondering what ray besides the blue spotted stingray would live happily in a 240 gal for it's entire life (no tankmates)? Also, I cannot find any websites that sell the Dasyatis kuhlii, they only sell the Taeniura lymna. Do you know of any reputable sellers? Thanks!

Urolophus halleri?
Hey guys, I was wondering if Urolophus halleri was a cool water or tropical
species? LiveAquaria.com has it as a tropical (72 - 78) but I've heard that it's
a cool water also.
<It's found from Northern CA, where temps are around 50-55, all the way down to Panama.  Keep in mind though that most individuals in the trade are likely coming from warm waters and may need to be acclimated slowly.>

Keeping Rays 6/6/05
I have a few questions on bat rays.  Today I went to my local aquarium and fed the bat rays.  I really liked how they suck on your fingers.  I wanted to set up a saltwater "Pond" in my basement.  I was wondering how I could get one and how much it would cost.  (a really small one)  
<Here is info on building a pond:  http://www.wetwebmedia.com/ca/cav1i1/pondDIYCalfo/diy-pond.htm.  See here for some basic ray husbandry and species selection tips:  http://www.wetwebmedia.com/marine/fishes/index.htm>
and I also wanted to know if it is legal to catch your own and keep it.  If you can please email me back with my questions answered that would be great.  David Moore <Generally, it is legal to collect livestock that is also legal to catch for food or sport as long as you have a fishing license.  Do check with the fish and wildlife department wherever you plan to collect!  Best Regards.  AdamC.>
