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.

Help please! My fish have been fine but tonight one of them started to look sluggish, he was leaning against a plant not moving much, I think he seems pale but not sure if I'm looking too closely he was struggling to swim so took him out and noticed a bubble like thing on his side, it was there for about 5 min then I watched it burst, not sure if it was an air bubble or cyst, but it was on him while trying to swim! Another one is now starting to seem to float backwards with the filter but can swim forwards, the one I have taken out does seem smaller than normal! What should I do?

My 1.5yr old Black Moor is head first in the rocks. His body is curved and he is seemingly trying not to move over much. I have tested and retested the water with normal levels. Tried feeding him peas for constipation. I got him to eat 2 pellets of food today by sinking them. There are no visible abnormalities to his body. I am at a loss for how to help him.

Do I need to stop my filtration of my aquarium, for clear water treatment?

I have a pond with goldfish and koi. One of my fish can't get up righted. It has plenty of energy but hangs upside down. 2 weeks now. Can I do anything to correct this?

    My Koi is doing the same thing.....don't know why....two weeks also...was thinking temperature snap to cold weather may have triggered but don't know.

My dad has a 'white' fantail like goldfish in his outdoor pond. The fish seems to be bloated at its back end, its top fin lays flat and most worryingly, it's head is pointing down, and its back lays just under the surface (sort of arched). I have thought it was dead a few times and gone to take it out of the pond, but as soon as I touch it, it swims off quickly to do the same somewhere else within the pond. Any ideas? I don't want it to be suffering.....

I have a 17 year old piranha and has recently started to lay on the bottom of the tank on his/her side most of the time. When he/she swims, its head is up and tail is down and and swims in circles. He/she is in a 60 gallon tank and he/she stays mostly at one end. We have fed him/her minnows for all these years from a supplier. He/she seems not to be eating. This has never happened before. Any ideas what the problem could be?

My Skunbunkin has been sick for a week and a half. I've been treating my whole tank (3 goldfish & 1 sucker fish) with the Lifeguardy all-in-one treatment for a 5 day treatment. Skooby started feeling better, but his belly is still swollen more on one side than the other. Also now he is staying at the top of the aquarium either for imbalance or oxygen.

I changed my water 25% day before yesterday and started back on all-in-one treatment again. What to do if Skooby is constipated (clear string hanging from butt) or he has swimmer bladder? Appreciate your recommendations to get his belly down from swelling. Thank you.

Hey everyone, my pot-bellied molly and cat farowella have recently died both in the last four days. They start by showing white/dull spots in their scales. Then within 12 hrs they have problems swimming and keeping their equilibrium, and hardly moved even when being touched, then eventually die. I keep my freshwater tank at around 76 degrees. I don't believe it's ich because of how quickly it hits and kills my fish. The only other disease I thought it could be would be neon tetra disease, but it's hard to tell for a beginner fish-keeper. Any help would be greatly appreciated.
