Fish identification      9/26/16
Thank you for the excellent website - and for the time you all take to respond to questions.
I have a spring fed natural pond that is 60 x 40 feet and 8-10 feet deep in the middle...(approximately 144,000 gallons).
The pond is in upstate New York; water runs in to and through the pond all year long and never completely freezes.
Every year there are tons of frogs.
This year I cleaned the pond for the first time since I became the land owner (7 years):
First I drained it down by re-building a trench at the end opposite from where water flows in, removed all of the cattails (two 12 foot long bunches at either end of the pond), turned over the edges (all of the way around),
and treated the pond with a product boasting "beneficial bacteria" and "safe for...horses, livestock, birds, pets, fish, wildlife and the environment" to help clear the water (it worked).
The whole process took about 6-8 weeks of work.
<A BIG job>
I was greatly rewarded.
I could see the bottom of the pond all the way around - and down to about 4-5 feet - for the first time.
(The water has a green tint but is quite clear in the shallowest parts.)
Three catfish (12 inches, 16 inches, and 20 inches) appeared and I occasionally feed (1x per week).
There is also a HUGE snapping turtle in the pond - he must be old (a foot long?).
<Get more than twice this length!>
I have never seen him outside of the pond. He just floated up one day right in front of me - it was amazing.
I am writing because of the seemingly dozens and dozens of fish in the pond.
They seem to be all different kinds and swim around in separate schools and the biggest, aside from the catfish, is 6-8 inches.
There are tons of minnows too. Some (minnows?) seem to move around on the bottom of the pond, and others float around the top and in the shallows.
Some of these unidentified fish/minnows come to feed and others do not.
When I first started treating the pond, I only saw two or three dead fish.
Attached is a photo of one of the fish that died (it was about an inch long).
Do you know what kind of fish it is?

They are skittish and vary in size. There are tons of bigger ones now (3 inches up to 6-8 inches).
The bigger ones are almost all orange - and it looks like black running along the top of them.
The little ones look translucent in the water - but the orange is obvious in all of them.
They are very very shy and will dart up to eat food and then very quickly dart away.
What are they?
<Pretty sure from the description, pic.... oblique mouth, scalature... colored fins, that this is the Common Shiner; Luxilus cornutus>
How can I help them survive?
<Take a read on the Net w/ the common and scientific names>
There are so many of them I wonder if the pond can support them - especially with multiple other schools of fish and minnows that I cannot identify.
Thank you very much,
New York
<Thank you for sharing. Bob Fenner>


White cloud mountain minnow has growth     7/26/13
Looking for some advice please. I have a few WCMMs and one has a growth/bubble looking thing near its mouth (others are fine). My local pet shop said to just leave it as long as it was eating ok-it was then but now its growth seems to be slightly bigger and pushes the food out of the way so my poor fishy can't get any food. Is there any treatment for this that I could try? It's had this growth for a quite a long time now-but only now does it seem to be causing trouble. Many thanks for your advice.
<Think we've had coverage of this sort of condition w/ Tanichthys. Please read here re:

Mudskippers; darter ID/PA    1/9/13
Hello, I was reading your postings about mudskippers, while trying to identify a fish my daughter and I caught in our local creek.  We are located in Langhorne PA, the creek is the Neshaminy Creek.  In all the literature we found, and talking to the local rangers, they have never seen and we have not found anything that looks like this fish.  The closest we have found is the pictures of the mudskippers.  I have enclosed a picture of one that we caught.  It is about 1-2 inches long,  (2 inches is the longest we have found, and 1" is the smallest we found) we mostly found them when we were hunting for crayfish, under rocks. Thank you for any information you can give me.
Cynthia Bridge
<Mmm, appears to be a darter of some sort/species. I put the search string "Etheostomids of Pennsylvania" in Google... Looks like an Etheostoma....

blue orfe disease    2/9/12
Hi there
Please advise! My 14" long blue orfe's body is bending and a little swollen where the tail meets the body and he is having a problem keeping his rear end under the water. There is a small mark or ? ulcer near the base of the body but otherwise no scale loss or other marks. He spends most of the time on the surface with head and body under water and his rear end/tail on the surface. He is feeding a little and doesn't seem distressed and can swim under water when startled from the surface. He has been like this for 18 months and is very slowly getting worse.
Please help! - thanks, Gina
<Orfe are prone to spinal deformities. Traditionally this has been put down to genetics, i.e., inbreeding, but it actually seems more likely that the deformities are caused by exposure to toxic chemicals. These chemicals can include medications, most of which should NEVER be used with Orfe without consulting a vet first. Apart from common salt, Epsom salt and antibiotics, most of the standard medications (such as copper, formalin, and organic dyes) should be assumed to be acutely toxic to them. Even if the fish don't die, the slight damage caused by exposure seems to be cumulative, so that over the months and years any damage to, for example, the spine, becomes steadily more noticeable. Apart from medications, water quality issues, lack of oxygen, physical stress and trauma can all cause similar problems.
There's no cure, but on the plus side, if the Orfe can swim and feed normally, a kinked spine doesn't seem to shorten its life any. Cheers, Neale.> 

Bait Shop 130 gallon - minnow tank  12/6/10
We have 2 old Dynamaster air pumps
<Wow, a blast from the past. Ahh, the olde Eugene Danner product line; noisy, but dependable>
with a combined flow of .5 CFM. Before we look to replace these pumps, it would be helpful to know if this enough aeration for this purpose.
<Mmm, a few ways to tell... if sufficient. Direct testing with a DO device... or better, simple observation, to see if your minnows are doing okay... not breathing too hard. I would get, use an ammonia, nitrite and
nitrate test kit>
In season, this tank is quite full and more than a regular aquarium. We would appreciate your insight. Thank You.
<Glad to help. Do the water quality tests above make sense to you? Bob Fenner>

Keeping minnows in a 10 gallon tank  1/19/10
I was wondering if it was possible to keep 5 or 6 rosy red minnows in a 10 gallon tank in the long run? Do they need tank length like the Danios?
Also would the tank fill with fry like it would with guppies or is there a way to prevent fry? Thank you!
<Short answer is no, this wouldn't be nice at all. Rosy Red Minnows are just like any fish and need a tank appropriate to their size and temperament. Cramped fish become ill-tempered, stressed, and often prone to disease. So why bother? For 10 gallon tanks, you want species that don't move about much.
Neons are quite good if the water isn't too warm (around 22-24 C) is ideal while Cardinals are a better choice for warmer tanks (26-28 C). If you're a more advanced hobbyist who's happy to research their specific needs, you
can also look for more difficult things like Ember Tetras, Celestial Rasboras, or Dwarf Rasboras (Boraras spp.). A group of 10 or more of these schooling fish in a shady, well-planted 10 gallon tank can look stunning.
And no, tetras, barbs, and Rasboras don't normally breed in community aquaria. Cheers, Neale.>
White cloud minnows  1/19/10
Sorry, I made a mistake when I asked about rosy red minnows. It was White cloud mountain minnows. I read they only grow to 1.5 inches and was wondering if that was ok for a 10 gallon tank in the long run?? I am assuming that fry may be a problem though. Again sorry for the mix up
<Tanichthys albonubes is a wonderful little fish, and it is, in my opinion, a borderline acceptable fish for a 10 gallon tank. Does partly depend on the size of the tank. If the 10 gallon tank was long, say 50-60 cm long, that would be better than one that was just 40-50 cm. Also depends on water turnover; a poky little hang-on-the-back filter that generates hardly any current really isn't the thing. These are hyperactive little fish, and if they can't play in the current and spar with one another among the floating plants, they're just half the fun they should be (and it's bad fish karma
for the aquarist). So I'd sit back, look at the 10 gallon tank, and ask myself whether it's a suitable home for a fish that darts up and down shallow, clearwater streams. Now, if you can stretch to a 15 gallon or better yet a 20 gallon tank -- and the space/price difference is trivial -- then a big school of healthy White Clouds is a thing of joy, and a group of ten alongside half a dozen Corydoras catfish like Peppered Corydoras (which like the same cool water) would be lovely. Cheers, Neale.>

Problems with minnows 7/29/09
I have a bait shop & my minnows are not needing air but they are not moving. They get on top of the water & just stay/ I have looked every where to find out on what to do. Any suggestions?
<Well, the obvious thing is to check your aquarium is adequate to their needs. Fish become lethargic when the water is too warm or too poorly oxygenated, or when the water has very low quality. Assuming that these are Pimephales promelas, this is a fairly hardy fish, but it does need an aquarium with good water turnover, at least 4 times the volume of the tank in turnover per hour. So a minimal system for these fish of around 100 litres would need a filter rated at 4 x 100 = 400 litres/hour. This should ensure 0 ammonia and 0 nitrite; if you find you have ammonia and nitrite levels above 0, then your problem is overstocking, under-filtering, and/or overfeeding. Assuming you're keeping lots and lots of fish in one tank, overstocking and under-filtering are by far the most likely problems. Temperature shouldn't be a major issue with Pimephales promelas, but they are coldwater fish, and anything much above 20 degrees C will stress them.
Different minnow species will have different tolerances, in general towards requiring water that is [a] cooler; and [b] more oxygen-rich, in which case faster turnover and better siting of the tank somewhere cool will be
important. Since you're running a bait shop, I have to assume the welfare of these minnows is fairly low down your list of priorities, but as someone who cares about fish, I would urge you to review their basic needs and act accordingly. It's bad enough they're going to be impaled on a hook and dangled in the water for goodness knows how long, but at the least make sure you maintain them adequately beforehand. Oh, and if you think I'm being preachy, well, this is a pet fish website, so I'm sure you can't have imagined we'd be okay about the use of live fish as bait! Kind of like a Korean chef asking an American dog breeder where to get the tastiest puppies...>
ASAP if possible
<Done my best!>

re: problems with minnows 7/29/09
I apologize for upsetting you with my questions.
<Wasn't upset, merely surprised.>
This is the first time I've ever had this problem. I change the water every 2-3 days. the temperature is 62 or lower.
<Well, test the water, rather than taking things on trust. Grab a nitrite test kit, and see what the water quality is like. If it's not zero, then that's your problem, right there.>
I don't know why you would take such offense at fishing for food but to each his own.
<It's actually quite complex. Certainly here in the UK, it's hard to imagine anyone angling for any reason other than pleasure. People haven't been made so poor (yet!) by this recession that they have to hunt fish for food. I'm not wild about using fish -- which recent evidence seems to suggest can feel pain, or something like it -- as bait. Even putting that aside, live bait taken from one body of water to another can transfer parasites and diseases.>
I have had koi, goldfish, crawdads, & I do take care of them.
<I'm quite sure you do. I personally enjoy fishing, though not so much as keeping them as pets. But I do try to minimise any suffering caused, and operate strictly on a catch-and-release basis. I'm a zoologist, not a tree hugger, and I respect anglers as being a massively influential and positive group when it comes to maintaining freshwater habitats. So please don't think I'm against angling. It's just the use of live fish as bait that, for me, crosses the line between acceptable and unacceptable. Other WWM crew members may well have their own opinions.>
I still have some as a matter of fact. Just change their water this morning. I my self can't hurt Gods creatures, I cant even put a worms on a hook. But the people who come in here are looking to put food on their tables.
<Fair enough. It's just not acceptable to me. Would I vote against it, perhaps, but here in the UK perhaps things are different, and fishing is entirely a sport, and while many do eat their catches, that isn't why they do it. A different situation, perhaps.>
They put the to small of fish back & only keep the ones that are edible.
I'm saying this with the kindness of heart for I know I have already upset you. So Your PREACHING" was okay & understandable.
Anyway I have the minnows in a 150 gallon vat & i think moving the water with filtering is what would help them.
<Agreed. You'll need a BIG filter for a 150 gallon system, something around 4 x 150 = 600 gallons per hour. Now, you may well find a pond filter more economical.>
I still thank you for your words & have visited your site many times looking for answers for my goldfish so I thank you for the knowledge that you pass along to others to ensure that things are okay. & that they have healthy fish.
<We do try; we're here because we like fish. A lot!>

re: problems with minnows 7/29/09
thanks for writing back never thought of pond filter system .
<Happy to help.>
I live in the states so that probably explains a lot. You know how things are messed up here.
<Wouldn't say "messed up", merely different. I've lived in both the US and the UK, and there are things I like about them both, and things about both that drive me nuts! But every time I go back to the US, as I am next month, it's like my second home and I really love it.>
I live in a very poor town & that's why there's so much fishing.
<No complaints from me! I love a fish dinner!>
very impressed with the zoo (shoot cant spell it) I find that very interesting. again Have a great day & God Bless
<And to you, too.>

I was wondering about 3 Minnows I found in the creek  5/20/07 Hi again, <Hello.>   I was wondering about 3 Minnows I found in the creek. I have a ten gallon freshwater tank with 1 scissor tailed danio in it. can I put them in there? <You can certainly try, but what species of minnow are they? Most minnows caught in cool temperate zone waters (e.g. the "northern" United States) will not tolerate the warmer water that the Scissor Tail *Rasbora* needs. Kept in a tropical tank, the minnows will die after a few days or weeks.> Also what fish go good with Minos? <In a coldwater tank, all sorts of other small animals could be kept with your minnows. I'd not add more fish though, because 10 gallons is too small for that, and minnows need swimming space. But snails and coldwater shrimps would work well.>   Thanks,   Kyleigh <Cheers, Neale>

Breeding Sarcocheilichthys sinensis sinensis - 10/21/2006 Dear Sir/s, <Or a madam, in this case.  Sabrina with you.> There seems to be lack of info re. the breeding of Sarcocheilichthys sinensis sinensis (Amur Sucker / Scarlet Carp / Chinese Lake Gudgeon). Literature found state that this fish has never been bred in captivity. <Indeed, this is all I can find, as well.> This peaceful species is an unusual addition to any coldwater aquarium. <And quite attractive, in my opinion.> I have introduced 6 specimens (approx 10cm) in my pond and was lucky enough to collect 24 young Amur Suckers this summer. <Wonderful!> Apart from Hornwort, the pond is occupied by freshwater mussels. I cannot really tell whether the mussels played an important role in the breeding since the pond is a bit deep. <Were you able to observe any spawning behaviour?  Take note of temperature and water chemistry during their spawning season?> I have experienced many species for these last 40 years but the breeding of S. sinensis sinensis is still a mystery to me. <To me (and seemingly all of us at WWM) as well.> I would surely appreciate any info / advice / expert reference. <I do wish I had more to tell you - but I believe you are probably more experienced with this now than many/most other folks in the aquarium hobby.> Best regards from Malta. <Best regards to you from California, USA.> John Farrugia <-Sabrina Fullhart>

What to feed newly caught lake fishies? NANFA.org  - 4/24/2006 Hi there... I did an internet wide search and came up empty handed on what to feed the fish we caught out of our local lake. We'd love to be able to keep them in an indoor aquarium or our outdoor 90 gallon pond; but I have yet to find what to feed them... We caught 10 spot-tail minnows, and 1 brim. (bream?) <Can likely be easily trained onto pelleted "pond" or aquarium foods... do seek out high/er quality of these... as some do a good deal of polluting>   Also.. could you tell me possibly whether they would survive better indoors or out? <Mmmm> We live in Alabama.. and the pond is made of black plastic with very little shading right now (newly installed)... <Well, best to be where conditions are more like their natural habitat... but stability is very key. If your house isn't too warm... versus the pond being too small and/or shallow... I'd keep them indoors> Anything else you might be able to add (or point me in the right direction) as to water temp/food/plants... <Do look up the website NANFA (.org) A treasure of useful information on natives, their captive care> for our new fishies would be wonderful!

Overstocked? - 07/16/2005 Okay, I know I write you guys all the time but I need to find out if my aquarium is over stocked if so how much? I have:  4 mollies [2 male ,2  female], 2 minnows <"Minnows"....  best find out what, exactly, these are.  Some "minnows" turn into quite large, substantial fish.> 2 African dwarf frogs, 3 neons, 2 harlequins and one bottom feeder that I do not know the name for( it is very long and skinny w/ a pointy nose.) <Very many possibilities here, as well - again, try to find out what it is.> My tank is a 10 gallon but I also have a little 3 gallon I could use. <I would not recommend stocking a ten gallon tank this heavily.> I'm pretty sure I have too many but ammonia and everything else seems fine. <If by "fine" you mean ammonia and nitrite are ZERO and nitrate less than 20ppm, you're probably okay for now.  Remember, though, as these fish grow, you'll probably need a larger tank, and more frequent water changes.  Test nitrate often to see how often you will need to be changing water.  Keep it as close to zero as possible.> most of these fish were just given to me and would have been flushed had I not taken them, so you might understand my dilemma. <Indeed.  I would also urge you to explain to the would-be flusher of the fish that he/she could have returned them to the fish store and possibly even received store credit for them.  Flushing a fish is NOT acceptable, and quite possibly causes a great deal of pain and suffering before the animal finally dies....  A quick trip to the fish store with a container of fish ensures that the animals at least have a chance at a healthy, happy life....  Additionally, if you fear your tank is overstocked, you might consider which fish you are most inclined to keep and then return some to the fish store yourself.> I also want you to know that I really appreciate your website and have learned a lot from it.   <I'm glad to hear this, thank you very much for your kind words.> Thanks, Angy <Wishing you and your fishes well,  -Sabrina> Strange behaviour in Golden Orfe I have a medium size pond (5.2 cu metres).

The pond also contains rudd, goldfish and shubunkins. Please advise!! <Sounds like there may be something awry with your water quality... perhaps an incident of over-spray for pests from somewhere nearby... or a change through warming of the water seasonally?

New Fish, What Kind To Get? What if i were to forget about the Betta Fish and just do tetras? Is there a fish that will go well in a 5 gallon tank that will do well tetras? All i want is to have sum pretty fish in my tank that will do well! Also what are the appropriate levels for he ammonia and nitrates or whatever and if there are high how do i take care of that? <<Hello. Good fish to keep with bettas would be white cloud mountain minnows. Nice, red fins and pretty stripes. The appropriate levels for ammonia and nitrites are zero. For nitrates, as low as possible, not higher than 50ppm. If they are higher, you need to do more partial water changes until they are within range. -Gwen>>

Fish Communities, II Two things, firstly, I'd like to thank Sabrina for her wonderful words of wisdom. <Sure thing, I'm always willing to help.> Second, I'd like to know what fish would work with tiger barbs and a rainbow shark. <Well, you said a "ten to twenty" gallon tank - provided the tank is large enough to house the shark (or that you get rid of it as it grows too large), there are tons of options.  I'd suggest sticking with durable schooling nippers, like Serpae tetras, skirted tetras, phantom tetras, other tetras of that nature, zebra Danios, harlequin rasboras, *so* many colorful options for you.  My two personal favorite fish of this temperament are rosy barbs and Rummynose tetras, very attractive little beasts.  One interesting approach might be to do mainly just tiger barbs, of the different color varieties, regular, green, and gold.  Perhaps some quick moving bottom dwellers, if the occasionally territorial rainbow permits, like kuhli loaches or smaller Botias.  You have gobs of options available to you.  Get a feel for what you like, research fish you're interested in, observe the animals firsthand at stores and in others' tanks.  If you're in a metropolitan area, consider  getting involved with the local fish clubs (*never* too young for that!)  I wish I'd known about them when I was younger - folks to share my fish addiction with and learn from would've been *divine*!  And above all, learn, love, and respect the animals in your care - and enjoy!> Thanks Brenda <You bet.  -Sabrina>

Whirling Disease? I have a school of shiners from Mississippi River in my 10 gallon tank. Two of the fish started to show signs of spinal deformations and they twist and whirl when swimming. <Yikes....  Not a good sign, at all.  Use strong caution, here - do *not* return any of these fish to the wild - if they have a contagious disease (and it sounds like they do), it could impact other wild fish very negatively.  As you describe this, the first thing that pops into mind is "whirling disease".  This illness is caused by a myxosporidian parasite known as Myxobolus cerebralis.  It's usually seen in salmonids (like salmon and trout), but has been seen in other fish as well, even goldfish and livebearers.  The parasites infect the tissues around the inner ear and the cartilage of the skull.  It causes the fish to swim in circles, sometimes frantically, or to swim nose-down tail-up, spinning like a top.  It is usually fatal, though some fish will survive and thereafter always have spinal/skeletal deformities.  It is also untreatable, I'm sorry to say.  If this is what your fish are exhibiting, I would strongly recommend euthanizing the sick fish, or at the least remove them to a seperate tank to prevent spread of the disease to your other fish.  If the fish die in the tank of healthy fish, the healthy fish run an *enormous* risk of catching the illness - hundreds of thousands of M. cerebralis parasites may be released by an infected dead fish.  Also, if the fish die, do *not* flush them, for the same reasons.  Perhaps bury them at the roots of a favorite plant, so they can "live on" as life given to the plant.... or maybe I'm just sappy and sentimental.  anyhow, I know this is a huge amount of bad news, and I am sorry to be the bearer of it....> Other fish (guppy, neon, danio and other four shiners) seem to be fine. The fish had been in my tank since September and had been given general tropical fish flakes. <They may never catch it, either, if you act now and remove the infected fish.> I also noticed that the shells of snails started turning whitish and have some abbesses, just don't look healthy. do I have some nutrient deficiency in my tank? <Ahh, this is a much easier, and happier answer.  You are probably lacking calcium or some other mineral that the snails need for healthy shells.  You can buffer the water with a calcium carbonate solution, but this may increase your pH, as well, so do so only with caution.  I'd also like to mention, since dosing my tanks with iodine for my freshwater shrimps, I have noticed AMAZING changes in the snails, as well - the went from pitted, white, eroding shells to rich, brown, faster-growing shells.  The change is very obvious on the larger ones, you can actually see the cutoff point where their shells began to grow healthy.  I use one drop of Kent Iodine (this is marketed for saltwater tanks) per every ten gallons of water in all my freshwater tanks containing shrimp.  The snails get it by default.> What to do?   <Just as above....  and do further research on "whirling disease", especially here:  http://www.fishdisease.net/cgi-bin/search.cgi?ps=10&q=whirling+disease&t=&Submit=Search .  Again, I'm sorry I don't have better news for you.> Thanks for your help,  Claudine <Wishing you well,  -Sabrina>

Sarcocheilichthys sinensis Hi. This message is for Bob. Some time ago I inquired information on Sarcocheilichthys sinensis. The reply can be found here: http://www.wetwebmedia.com/FWSubWebIndex/fwfishfaqs.htm <Oh, yeah... see Anthony replied... re a "Chinese High Fin Shark/Gudgeon".> Thanks for those replies. The guy who posted in the forums on fishprofiles.com was me :). I have also written a profile for the site that should be in their index soon. I do know that it comes from the Amour river which is the border between china and Russia, and a few general pieces of information. Information about this species is limited on the internet. Breeding info, or just finding someone else who keeps this fish would be great. Can you help me? As far as I know I am the only person in the states who keeps this fish. <There are a few references (for information) listed on fishbase.org for this species. Go there on the net and key in the scientific name, click on references: http://www.fishbase.org/References/SummaryRefList.cfm?ID=47349&GenusName= Sarcocheilichthys&SpeciesName=sinensis%20sinensis This is about all I know...

Re: Sarcocheilichthys sinensis Thanks for the link and the quick reply. Have a great weekend! <Thank you James. Do consider keeping notes, writing up this fish, it's captive husbandry... someone needs to! Bob Fenner>
