I had a redtailed shark, a catfish and a three-spot Gouramiin a 30 gallon tank for over two years. I recently bought a new 40 gallon tank, followed all the steps in start up per direction. I bought five white mollies from the pet store, placed them in the new tank and after two weeks introduced the older bigger fish. Now all of the fish have died, I think it was flukes. Would the new fish I bought have had the diesease? What should I do before I get new fish again?

i have a fish that just died recently. It had clamped fins, bloated eyes, and a loss of its scales. I have a few other fishes that have clamped fins but no other symptoms. I tried using coppersafe but it doesn't seem to work. What other medication would help? Please help me. I have this huge kio fish that seems like it;s about to die and I would love to keep him but it doesnt seem likely right now. It goes to the bottom of the tank and stays there. It only moves occisonally. How would I be able to save him? and if the fish is infected, should i isolate him so it wont infect the other fishes?

    What type of fish? Have you checked amonia levels? This should always be done before medicating.

    Andy, there are a few different medications suggested in the above article where the conditions include clamped fins. Please try any of them. If it's a fungal issue and you have an adequate tank to isolate your sick fish, always do so, otherwise, treat the entire tank. If it's a parasite, that would benefit all other fish anyway. Hang in there.

    I forgot to mention the most important thing, the cause of this issue very likely started from the water condition. Take the time for regular changes and keep that water clean. Invest in a testing kit, not just the strips. After being plagued with sick fish every month or so, I started changing my water every other week at 15-20%. I haven't lost a fish in over a year. I also inspect them often to note anything changing with their behavior or fins. The sooner you detect a problem, the easier it is to treat.

I gave my silver goldfish to my neighbor when it started attacking my tiger barbs. She asked me to look at it today because it was looking ill. She introduced a new goldfish about a week or two ago, they both are lethargic and having difficulty breathing and swimming. They have white spots and a clear substance on their bodies. Their color is dull and their fins and mouths are clear with red streaking ( I assume where the veins are). The fins hardly move and seem shorter ( not entirely sure as I haven't been over to see the silver in awhile). I think it is Marine Ich but not sure. I'm worried we might be to late to save them. Can anyone help me with a definite diagnosis and a treatment. Preferably a cheap one beings as she is disabled and on a fixed income. Oh and there was some gross greenish clear gunk on the fake plants. They are the only fish in the tank and not sure of gender on either ( I am very new to goldfish and she is even newer than me) Please help me! Thanks!

    It sounds like you have several things going on at one time. ICH is the usual demon. I would look at the symptoms in the above Animal World article to see what other symptoms it might be and treat for what describes your situation the best.

I have a bright reddish-orange cichlid i think? Different places seem to call him different things but when I look him up he resembles a cichlid. I love him to death and just recently we had a figure eight puffer develop grey patches starting at his face and working down his body and soon after died. Now my little Sampson has developed the same thing. It seems to have all popped up at one from his face all the way to his back fin. His personality has changed dramatically. He's much more active and eating much more. Normally he is very non aggressive but now he doesn't want anyone around him. We went to the pet shop and they gave me something to cure Ich. But it looks like it's getting worse. Is there anything else I can do for him or is it just a waiting game now? I just don't want to lose him.

Hi, my brother is out of town and left me with his yellow fins. In these three months of taking care of them I saw never saw any strange behavior until I got to my office this morning and saw that one of them (if not mistaken, female) was lying dead on the sand without and eye and a hole on its stomach...I've been feeding them properly and last night when I left they were all doing great. Can someone please tell me what happened? I'm new to fish caring and would like to know a bit more on how to take good care of them. From what I read, the tank my brother has put them in (now three, used to be four) isn't too big and I've seen them push the sand so it caves up. I currently have two male and a Female in the tank, is there anything I need to be aware of?

    Actually, it sounds like aggression on the part of one of the fish. It could be breeding behavior or just territorial in nature. How big is the aquarium and how many yellow fins do you have in it? Is there any sign of one of the fish being aggressive towards any of the others?

    Dear Maria, what substrate do use? There could be a chance of fish trying to dig and ended up with a piece stuck in its throat or it could have hurt its eye to your rocky arrangements. Or it could be due to stress.
  • Chris - 2012-05-13
    2 males and 2 females in a tank is a bad ratio to have. You want to have at least 3 females for every male in the tank, or they will be harrassed to death. They have been mounding up the sand to establish a breeding area, which makes me think the female was killed because she wasn't interested in breeding at that time. I know this is an old thread, but I figured I should respond to help others with the same problem.

    They are still juveniles, did you just get them? What are your water parameters? My first thought is the water quality is poor.

Hi there all fish lowers, I have 3 inch long flowerhorn fish.
From last 2 months, I had noticed that he was not eating food because he can't see it. He is eating by judgement. Neither his eyes are popped out but both pupils seem little bigger. He swims lethargically and not at its actual way. Skin looks normal. Have given tetracycline 3 times. But of no use. Water conditions are good enough. I am not able to make out exact symptoms from your chart. Pls.advise.
