I recently added two smallish Bala sharks to our planted aquarium. They showed a horrible outbreak of Ich after 3-4 days which I assume they brought in with them since I have never had it in my tank before. I have been treating them ~2 weeks now and one has recovered and the other is almost free of ich spots, but seems to be having swim bladder problems now and a little bit of cloudy eye (swam sideways a few days, now seems has to swim constantly to avoid sinking to the bottom). Does anyone know if the ich parasites ever cause swim bladder damage? Fish wants to eat all the time but has difficulty maneuvering to get food and is losing weight (probably from the constant swimming). I am unsure whether to try to treat or whether to give this one up as a goner due to swim bladder damage...any ideas?

My koi fish is showing signs of deterioration of her fins, and this morning I went to check on her and the scales on her abdomen turned into a yellowish color, there is small redness here and there with the yellowing scales. I'm really worried, and would appreciate any advice on how to care for her. Thank you.

I have a cichlid tank and all of the sudden once I introduced angelfish to the equation, my beautiful parrot fish just started dropping off like flies every day one would float to the bottom of the tank could not swim and would not eat, they would also get paler in color and within 12-24 hours they would be dead. Please anyone know why? I'm stumped.

    Angel fishes won't live with parrot cichlids because parrots are actually meat eaters & as the angel swims in a slow motion the parrots will think she is ill and attack on them I had the same here & after ones death they all become extreme slow.

One of my paradise fish just stays in the corner of the tank all day and night above the filter. The other 3 are fine. What can I do?

    If she/he is eating then don't be disturbed fishes just like the heat or massage of the filter.

I have a Red Devil Oscar, I noticed that he is breathing funny like he is gasping for air. He looks like he is turning purple on his insides he will act like he is trying to throw something up but can't then just a couple of air bubbles has come out (sometimes). Do you think he might have swallowed a rock or something? He won't eat he won't even try to get the goldfish that's been hiding from him. I noticed a hole on the side of his face about the size of a pencil eraser when he opens his mouth I looked in it with a flashlight and can't see nothing in there. It's like he was wanting me to see to help him. Don't know what to do or diagnose him for it's been 5 days as of today.

Hi, my goldfish has developed black spots on its body on one side and his gills. It is not tail and fin rot. Eating fine, no other signs of distress. I have used multi cure. I work in a pet store and haven't seen this before. Thanks April.

    Hi, I just treated my fish tank cause I notice a lot acting weird they were fish flashing they would itch their sides on gravel. So I treated them with a antibacterial treatment. Then I noticed they stopped well my oranda goldfish had a bunch of black spots covering whole body in huge patches and also on fins. Well just recently notice and couldn't figure what was different about him cause I work a lot and notice all the black spots was gone yah it's a parasite. He never had signs of not eating or nothing. Now noticed all fish are healthy and really bright in there coloring. The stuff treated tank with is called MELAFIX antibacterial fish remedy you treat up to 7 days. Yah I thought I overfed my other fish in tank but they were killed by this parasite also there was no signs of parasite besides noticing them trying to scratch there side of body on gravel.

    Hello, this happened to one of my goldfish, his fins turned black and it looked like he had a little mustache. I didn't use any treatment except taking 2 larger fish out the tank for aggressive behaviour. He eventually turned pink and lived for 5 years. Sadly swim bladder got him in the end. Good luck.

    It is ammonia burn it happens when you put your fish in bad conditions then it scabs over and create a black spot this is a good thing because it tells you your ammonia levels are going down.
