Hi I have a smallish yellow fish in a community tank in serious trouble. I do not have a first aid tank unfortunately to isolate him as no other fish are ill. It's fins have rotted off with red patches think its the red bacterial infection you write about on this website. It's horrible to see him suffering. Is it best to attempt to kill him? I will feel bad doing so but may be putting him out of his misery? Think it is too late for treatment. He can hardly move now. He has been dying for days. Thought he would be gone ages ago.

    I have the same problem. He still comes up to eat and when I go near him. Been going on for a few weeks. I haven't seen any white feces though. Been using malafix and stress coat but doesn't seem to make a difference. All other fish are healthy.

I have south american cichlids and they seem to be lethargic, slight appetite loss, and my oscars occasionally swim sideways. Has anyone ever heard of something like this?

Hi I'm jess and my goldfish is floating side-ways on the top of the water in the corner and he doesn't move. Every now and then he swims perfectly. Can you please help find a cure. My other fish died of a bladder disease and I don`t want it to happen again.

my goldfish's body is bloated to double the size and along each side is coloured red. I thought at first it might be carrying eggs but it has been like this for six weeks therefore i think it has a disease. Does anyone recognize these symptoms and is there anything i can do?

Hello! I wish someone could help me =(.

I have a 55 gallon tank with 2 goldfish. When I got my big goldfish he was in kinda a bad stage, I put some melafix in the water before entering the new fish. He had like 2 round balls in his head with like a white string in each ball (like a pimple with a white string) the other medium goldfish ate those strings, and since then the medium goldfish has been poking the other one. Not like bullying I think it's more like suckin on him. Like eating something from the other one. I noticed now, there's a part on the big one (a black moor) that you can see his scales (I think the other one did that), and the black part (his own skin) is gone a little. I put him in a hospital tank with some antibiotic, because it looks like a fungus. (tetracycline). It's been day 3 and he's releasing a lot of slime from that part of the scale.. what can it be? I'm so worried?..
I'm from panama central america and I haven't been able to found a decent vet..there's no fish specialist here and ppl in the pet store seem to give me vague answers, things work like that here. I'm trying my best to make him feel better but I don't know what to do. Please any tips or ideas?

I have a 20 gallon fish tank with a rosy barb, a mollie and two glass fish. Around a year ago I noticed the mollie on it's nose every so often (not on the bottom just suspended in the water nose down). After a few seconds it would straighten up and appear fine. Over a number of months it progressed to being on its side for a short period and then it would straighten up and seem fine again. For the last 6 months at least it has been laying on its side on the bottom of the tank. It still moves around and I assume eats since it's still alive. There aren't any outward signs of illness or injury. Any idea what would cause this and whether it can be treated after this long? All of the fish are around 5 years old.

Just bought some Dwarf Gourami's about 3 days ago and they were doing really good. I noticed yesterday that one didn't seem to have the same appetite as it once did and it was hanging out in the plants. Today I just noticed it on it's side on the bottom of the tank. This is my first time with Gourami's so I'm not sure exactly what this means. It does every so often sime a little but not like it was. I have tested everything you can imagine as far as the water goes and all levels are where they should be. If anyone has any insight that would be most appreciated.

    I don't know what your problem is, but I had the exact same situation. 2 weeks ago we bought a Powder Blue Dwarf Gourami which did great for the first week then I started noticing a loss in appetite and hanging out at the bottom of the tank. 36 hours later it was laying on it's side but trying to swim a little every now and then. It died that same night. I do water changes at least weekly and water tested normal. Not really sure what happened, but sounds exactly like your situation. Dwarf Gouramis are supposed to be especially sensitive to water conditions so I suppose a very small change in temp or other levels could have been the culprit.

    Many commercially bred Dwarf Gouramis carry a virus and the symptoms are consistent with what you describe. Some forums advise not to buy them as you will be lucky to get one that is ok and does not die within weeks or months at best, of purchase.

I recently got a new 60lt tank and after cleaning the gravel several times and letting the "dust settle" I bought a few fake plants
And some new fish... 3 Algae eaters, 1 "cat fish" looking & 3 others... I prepped the tank with the
Plants, filter, bubbles & heater however 6 of the 7 fish have died. The water was cleaned
Before with a chlorine & heavy metal binder "Sera" and enough oxygen tablets the day before..
I made sure that the new fish had an opportunity to "adapted" to the new tank before I put them in.
Please help.... I don't know why 5 died, 1's alive & the last is swimming upright half bent over
And gasping for breath... All fresh water fish. In a 26 degrees tank...

    It sounds like a problem with water quality, common in new tanks.The presence of uneaten food particles and fish waste can lead to raised nitrate levels. This will cause fish to die. In my experience bottom feeders are among the first to go when nitrates are too high. The way to avoid this is regular partial water changes (20-30% at least weekly). You can also add liquid bacteria formulas that reduce nitrate levels, and this should be done after water changes. Loads of different types are available in pet shops. Good idea to use a testing kit to check on water quality once a week.
