Hi, I have an oranda and he has large blister type lumps on one side, he has had these for 6 months, since I have owned him. Some times other lumps appear but go again in a day or two. They have never seemed to bother him, although they sometimes are blood red they tend to go back to a normal colour, but today he seems quite poorly. The lumps are red and he's not himself, thank u.....

    Because of the color it could be internal parasites. A little more info would help to answer your question more throughly.

I have several african cyclids that are showing signs of some type of disease that affects the scales. On one there are several patches of raised scales on each side of the cyclid with a kind of white tint to them. Another has lost some scales in random areas of the body and looks patchy in color. He is a bright orange african tiger cyclid. In one area it looks like something white is next to, or inbetween the scales. Any suggestings for diagnosis or treatment would be much appreciated. Thanks, Becky

    Sounds like it may be a thing called Dropsy, it is a type of edema. Does the fish have a Pine-Cone type appearance? Dropsy may be treated with antibiotics such as erythromycin or minocycline. I would also add 1teaspon per 10 gallons and raise water temp to around 85 degrees. Dropsy is very hard to treat but you may save some of them. Water conditions are key to preventions. Check your levels.

Can Someone help me? I have an about 6 year old carnival goldfish, he lives in a 20 Gallon Aquarium with no other inhabitants. He usually would swim around and only rest when you didn't look at him for a long time. He is a common Goldfish. We put a moss ball and suckerfish in his tank 3 or so weeks ago and he was fine until about 5 days ago when he started drifting to the bottom looking like he was dead. But when we would walk in he would sprout right back up and swim around towards us. The next few days he started moving less and less. He then started to get small red spots on his gills. I noticed that the sucker fish would be sucking on his scales while he was at the bottom. We have taken out the sucker fish because I thought it was hurting the Goldfish. He is now laying at the bottom flat breathing heavily. One side of him is completely red and there is what appears to be slime? or cotton like fungus. He hasn't eaten in about 3 days and he usually eats. Can anyone help quick?

Hi, I purchased 2 catfish about a week ago. When they were both netted out in the shop I noticed 1 of them looked really blood streaked. The assistant just said it was stress but it hasn't got any better. I have noticed that it looks really fat like it's pregnant. It's just really pink and red looking especially round about its fins. Can anybody help me out if they think they know what it could be??? thanks.

I had a Red Dwarf Gourami in a ten gallon tank with a tiger barb, a Serpae tetra, and two glo fish. He stopped eating and was a little bit more mellow. At first I didn't think much of it because he is shy, but he started bloating. He rarely pooped and when he did it was Hair-thin white strands. He died two weeks after the symptoms started. All the symptoms sounded like Malwi bloat, but I'm still not sure. What was it?

    Did you fish have a reddish ring around anus? The is a key sign of Malawi bloat. The white strands make me think you may have a different type of parasite in your tank. Maybe look into treating tank.

I previously posted here regarding my Black Moor (a year ago) and at that time knew NOTHING about these awesome fish! I started with a 20 gallon tank and feeding koi pellets. Now Marvin is in a 44 gallon tank and is fed a mix of nori, blood worms, peas, and fish veggie flakes. I make little ice cubes with the above ingredients mixed together and defrost one at a time. Marvin is about 8 inches long with fin and without, about 5 inches. She does have discoloration on her 'butt', not sure what else to call that portion of her body? Unfortunately every time I tried to introduce a new fish, it just didn't work out. One died of fin rot and the other died of anchor worm and infected Marvin as well. At one point she had approximately 35 of those suckers!! Thank goodness she is a larger fish so my husband and I were able to tweeze them off and medicate her after the fact (melafix/salt baths). We change 25% of her water weekly and 75% about every month or so. Here is my new worry, being a fish hypochondriac, today I noticed her floating, like she is nodding off and then 'comes to' and swims or shimmies a bit and then starts to sink a little. I am sure water is good, no diet change and I cannot see any other issue but the discoloration? It is light gold, about the size of a quarter. She is a fat fish, definitely doesn't starve. Help? I wish I could put a picture up here.

My work has a 20gal fish tank it has 5 fish in it. One common goldfish has what looks like to be green stuff/ fungus in its eye. Im not sure if its blind. I can also see a tumor or cyst on its side that has burst about 2 weeks ago and then reformed. The fish appears to be swimming on and i don't see any worms or spots on it. Im not sure what to do. None of the other fish have this problem.
