i bought a fish 3days ago and it was fine for a day. 2days ago it wasnt as active and was floating around. Just looked at my fish 2hours ago and its fins are shredded into little bits,its at the top of my tank lying there, its still alive. This is the third time this has happened 2 my fish. Ive added ESHa 2000 which cures Fungus,Finrot & other bacteria infections. Can anyone tell me what the cause is, Thanks In Advance

I have a 3foot tank. I dont think any fish have been attacking it. if they start fighting i put them in a different tank

When was the last time you did a partial water change, this sounds like poor water quality, the fish you have are fine as they've acclimatized over time to the quality of the water however, as soon as you've introduced the new fish the toxicity in the tank has started killing it.
Filters will convert some toxicity into less harmful toxicity, however as the water evaporates you top it up with more water all thats happening is the less toxic buildup starts to become a problem as it increases in Parts Per Million of the water, do a 30 pct water change and you maybe able to save the fish.

We really need more details to be sure, but if this fish is going into a tank or bowl by itself, then it sounds like you are having ammonia issues and should cycle the tank before adding fish. If this is not the case, please fill in more details about your tank.

ADDITION: As quickly as this happened, I would rule out disease as a cause. Even quite fast moving diseases that cause that type of damage take longer than your time frame. I would look to double checking your water test results, it's possible your kit is bad so try to have the water tested at a shop just as a double check.
Also, as others have pointed out, any fish can get a bit territorial and attack new fish added to it's environment. Many fish act totally differently when someone is in the room than when the room is empty. They see motion in the room that distracts them or they are waiting for food... various reasons, but it's true that they can and often do act differently. You may try sitting quite still across the room from them for a while and see how they act. Grab your favorite fish book or magazine and settle in for half an hour and watch them a bit.
It's my opinion that one of these two things will reveal the cause of the damage.

Even with all the additions to your question, you left out total volume of the tank and what you actually tested for. I have had so many people tell me that their water tested fine, and then I find out that they only tested for pH. In an established tank, you shouldn't be having issues with ammonia or nitrite in most cases. You said you keep adding medication, so that might kill off the beneficial bacteria, and cause ammonia or nitrite problems. You should also test for nitrate. Comets can also be rough on the fantails, so that could be your problem. No matter what, your tank will soon be overcrowded. I'd look for a pond for the comets and keep the fantails. Good luck!

Believe it or not, I once had a plecostamos that attacked the fins and tails of my other fish!! I don't know if he wasn't getting the proper nutrition, or if he just had a mean streak, but my poor comets had wicked sad-looking fins, etc. and I couldn't figure out why until one day, totally by accident, I happened to witness that nasty little pleco rasping away on my other fishy's tail. The comet would shake him off and swim away, and the pleco would chase him down and attach himself right on again, all while the water was turning pinkish with the blood the pleco had drawn! Needless to say, that was the end of that pleco in my tank. I would look closely at your pleco, if I were you.....surely I didn't have the only vampire pleco in existance!
Hope this helps.

Sounds to me like a case of over crowding. How many gallons is this 3' tank? It probably can't support more than 2 gold fish.

The Goldfish that you had for a long time is attacking the new Goldfish. How big is your tank. For the number of fish you have, it would need to be about 80 gallons or more...

Did you cycle the tank? It may be dying of ammonia poisoning. Put the fish in a smaller container with dechlorifier and do complete water changes every other day until you get your tank cycled.

What kind of fish is it? It could be due to the water temperature.
