I bought some gold gouramis and had them for three weeks, before I put them into my larger aquarium. Five days later, I lost some gouramis and had to make a 65% water change. I took the gouramis out and isolated them and lost 4 of the 7 gouramis. The other aquarium, which I have small gold severums and angelfish for at least 2 months started breathing heavy and lost 4 fish so far. The gouramis definitely brought something into the tank. It seems to be a parasite or viral infection that is attacking the gills. Any information of what to do with medications and suggestions would be greatly appreciated.

    Firstly, if you have multiple tanks why not make one a quarantine tank? Also, the breathing may be a sign of velvet:
    "The best treatment is with copper at 0.2 mg per liter (0.2 ppm) to be repeated once in a few days if necessary. Acriflavine (trypaflavine) may be used instead at 0.2% solution (1 ml per liter). As acriflavine can possibly sterilize fish and copper can lead to poisoning, the water should be gradually changed after a cure has been effected."

I have a parrot fish. She does not swim but stays with her head downwards and tail up. She has something white like a tube coming out from her anus. Please help?

    The tube part may be a nematode (parasitic worm).

Hello, my swordtail has recently developed a holi ender his mouth and his head looks like it is molting. What is this, and is it contagious to my other fish?

One of my full grown angel fish (freshwater) got itself stuck between the spoge cover on the outtake tube and ground down its fin, part of the side scales and it appears that its eye may be affected too. I put a little aquarium salt in the tank (it is a 45 gallon tank with 4 angels, 4 swordtails, 6 corys and 2 pitbull cats) the water tests good (we have well water) and all other fish are vigorous and healthy. The fin is about half there, the side swipe looks like it will heal, and possibly the eye (which has a milky scoured look), will the fin grow back or just be small now?

We have a Comet who is gold and about 8 inches long. My son won him at the fair exactly a year ago. The past few days he has had black on both sides. It started as a black dot on one side of the head and then both sides and today there is black on the lower part of his body. Sometimes his fins are up and he seems fine and then they are down and he just seems to float. I read through the list of diseases but nothing seemed to match. Right now he is just suspended with his head pointing down. Thank you if you can help me. If we lose him, my son will be devastated.

    Black patches can be a sign of ammonia burns. What are your water parameters, how often do you do water changes (and what percentage do you remove) and what size tank is the fish in?

I have an oscar, and he came down with some kind of problem. He can't stay under the water, it seems like when he trys to go down in the tank he gets pushed back up. If you have an answer please email me at bigshepered@aol.com, thank you.

I have 6 carp fish in my aquarium but one of them has the tail bent to the left, and become unbalanced in swimming. It has low appetite and movement normally less than other.

    Carp should not be in an aquarium... they get extremely large... the fish will outgrow its space.. & because it is in an area that is too small for it... the fish will actually break in half as yours has... even tho it doesn't seem that the tank may be 2 small just yet.. it still happens.. they need a vast area like a lake.. I've seen this happen a couple of times now.. they eventually died.
