I have a Korean Blue Angel, and it has developed some round patches of sorts around his face ..they take away the blue color, but his stripes can still be seen through the patch. Any ideas on how to treat and what this may be? I have several other types of fish in the tank as well, but they all seem unaffected.

We have 2 male dwarf gouramis for about a week and a half an one is starting to get a light dusty brown from just after his nose an goes up along his forehead an a little further, his appetite has decreased, if not stopped and he's hiding in the top of the plants under a lillipad, his breathing is laboured and he's taking slower bigger gulps, and he appears to have tiny minute little black spots (can barely see them) all over his body, not sure if that is part of their colour. Apart from the black spots, would the other symptoms be a sign of velvet, any advice would be much appreciated?

I have a young goldfish and she usually lays at the bottom of the tank and even on her side. Her back is curved in a "s" shape way and was like that when she was a small baby. One side of her is flat while the other side sticking out. She swims as if she has swim bladder disease. Could this be swim bladder disease caused by a birth defect and how can I treat it?

I live here in Florida and have an outdoor Koi pond. I have 2 ornamental goldfish and one is "listing". He lays sideways on the rocks and swims that way too. He does have an appetite. I feed the fish (I also have 2 large Koi) the Tetra Koi and goldfish food only once a day. What is the cause of his problem and what is it?

    Ichthyosporidium or swim bladder disease? It would help to know what other symptoms you checked for (ex. how closely did you look at the gills? did you check for extra slime?)

I have a Black Ghost Knife Fish. He has an area size of a dime with a white cotton like debris. (Fungus?). Have him in a hospital tank and been doing 10% water changes and also been giving Maracyn. He has been like this for almost 2 wks. now. Is it safe for me to remove the white cottonish debris? Seems that it is ready to come off. Although the area is completely covered.

    I wouldn't touch it. However if you read the first entry under fungal diseases it says that severe cases can be rubbed with a medicated cloth (see entry). At the very least be very careful what you try to remove it with.

My goldfish died yesterday due to an unusual swelling of the body. It was like it had a bocce ball in it's stomach. We thought it was pregnant. When I cut it open, a large red mass of bloody watery jelly like substance was inside. The outside was swollen scales and water blister type bubbles that squirted when touched.
What can this be? The fish had to be about 9-10 years old.

    Protozoan diseases tend to cause difficulty breathing, namely velvet ind ich. "Coppersafe, Quick-Cure
    Ich-Ease, Aquari-sol, Cure-Ick, Super Ick Cure". Bloat is possible, how much is it eating?

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?
