My koi, which is 37 inches long and 15 pounds has isolated itself in the shallow end of my pond, it has developed blister like bubbles from the nose area up each side of the head and acts like it is blind. It tolerates the other koi but when they swim to the deeper end of the pond, this fish bumps into the side of the pond. I have not been able to match any illnesses or diseases with this symptom.

    I can't say for sure what is wrong with your koi, but have you tried treating him for anything? He may be stressed out due to a variety of causes and it may be best to isolate him. I would first try a topical bacterial treatment or bath, as well as try to feed him medicated food specifically for koi.

My Blue Tang Likes to play dead! She'll lay on top of the tank on her side for hours and I think she's dead, but then all of a sudden when I feed she'll just get up and start feeding! Is this normal?

    Look at Fish Diseases and symptoms and scroll down to symptoms - Usually when the behavior is that odd - it is tank conditions. Check the symptoms and coresponding treatment is recommended but also throughly check your tank conditions, water, temperature ph etc.

I have had a beta fish for exactly a week now. He is in about a 10gallon tank so he has plenty of room to swim. It is lighted, contains a filter, and a few fake plants. For the first few days he seemed fine, but when I came home one day his top fin was tattered. I noticed that the sides of the tank were reflective and that he swims along them constantly, so I bought a background and some tall plants to keep him from seeing his reflection and getting too stressed from seeing what he thinks is another male fish. I first thought stress was the cause of the fin loss, and maybe that he was attacking his own tail thinking it was another fish, but ever since I have blocked the reflective sides his fins have gotten worse. His bottom two fins are starting to look badly tattered now. Each time I look at him he seems worse, but he is swimming just fine and seems happy. I do water changes and I feed him two flakes of food at the beginning and end of the day. I am really worried. This is my first fish, and although I've only had him for a week he feels like family. Is this fin rot or stress?

    It sounds like fin rot. Its hard to get tattered fins if there are no other fish in the tank unless he's tearing them up on the plants. It couldn't hurt to try a fin rot medication.

    Thank you. I will go get some medication today.

Hi, i have recently noticed that my male gourami has been attacked by the fin nipping flowerhorn and has become ill, since then i have separated the male from the main tank into a smaller one with some previously hatched fry in it. He refuses to eat the fry and has been either floating at the top and breathing rather heavily or sunken at the bottom and lisping quite hard. I am concerned for the fishes health yet do not know what else to do. He has been eating little to none and is very dark in color. Any suggestions?

    Animal Word article on Fish Diseases and Treament is attached. Scroll down to symptoms to see what best describes your little one's symptoms and recommended treatment is there. Behaviors are usually a sign of tank conditions/stress also so check tank conditions. I would be a little strssed and possibly hurt if someone bit my tail off but check tank conditions and also symptoms. OK Let us know....

Four of my fish (two are goldfish and I don't know what the kind the other two are) look like their growing whiskers. Long whiskers. But I don't think goldfish are supposed to grow whiskers. Any idea what it is?

    I can't known what they are - just haven't been introduced. Look at Animal Worlds catfish and see if anything looks similar. OK?

I have a young common pleco that I bought just a few days ago but I'm pretty sure when I first got it, it didn't have as many yellow spots as it does now. The spots are covering its body and are about the size of grains of salt. But they aren't flat. They're bumpy. Is it some kind of growth that needs to be treated or is it not something to worry about?

    Sounds like what they call ick or ich. Look up symtoms and the corresponding treatment is recommended. ich is salty like bumps spots on a fish - but Animal World describes it way better so you shouldn't have a problem. Just do the recommended treatment for the symptoms your guy has. OK? Let us know.

    I put him in his own tank and put the suggested amount of medication within. Overnight, the yellow spots reduced to half the amount and those of which stayed, have shrunken size by a lot. Thanks for your advice. =)

Hi, I just put in my 4 serpae tetras and my busy nose pleco in my 20 gallon tank and I added the water conditioner in my tank yesterday. This morning, I looked at one of my serpae tetras and he was breathing hard and the rest of my serpae tetras were not. Is it because I didnt put them in a tank for 2 days after I was cleaning my tank because my old fish died of ick?

    Could be the holding tank conditions while you were cleaning out the original tank. Could just be stress because of being moved all together. Could just be for no reason at all. I'd read up on Fish Disease and Treatment as lots of info that might help - also goes into tank conditions and moving etc.

I have 1 standard gold fish and 1 calico goldfish. My sister also has 5 freshwater minnows she caught and raised. They all live together. Originally we had them in a 3 gallon tank since July. This past Sunday I swapped them to a 5 gal tank with a filter. The water was constant mucky in the 3 gallon no matter how often I changed it. They never bother eachother
Since I changed tanks, I noticed one minnows tail is fraying badly and both goldfish have minor fraying in Thier tails and some scales missing. There are also a few white spots on them. I bought a treatment meant for ich and other illnesses. I'm worried about them and I'm hoping this 5 day treatment works.
If not can I use my antibiotics to treat the fish? Or do you call a vet?
Any help is appreciated!

    I think one of your biggest problems is your tank is way too small. You should probably go to a twenty gallon with that many fish. Also, goldfish are notoriously dirty and can sicken other fish. The small tank may be stressing them.

I have two goldfish one a fan tail and the other a goldfish my daughter won at a festival. The (fair) goldfish has eaten the fins off of my fan tail! He is floating upside down. I have seperated them and now I am wondering if he will grow fins back or live at all! Any help would be great!!!

    Attached article on Fish Diseases and Treatment. I'd look up the symptoms and see if corresponding treatment. Sounds like the one fish was ill and the other fish might have wanted to protect tank and enviornment. How big is your tank? Check out symptoms and see recommended treatment. Doesn't sound good that he is on his back like that so I don't know if much can be done. But we can learn so it doesn't happen again. OK?
