Hello to all, I found a good deal on a used acrylic 5 gallon with heater and filter (used) to be used as a hospital tank. I went to pick the tank up last night. When I arrived, the guy had 3 feeder fish in it and hadn't broken down the set up because he had gotten home later than expected. He said it would only take him a few minutes to "get rid" of the fish and dump the water out. He was going to flush the live feeder goldfish down the toilet even though they were still alive. I couldn't stand the thought of this so I asked if I could have them. Needless to say, the water was very dirty and the fish did not look well (breathing rapidly, gasping at the surface, very red gills and a lot of missing scales). I don't know much about goldfish but I want to try to help them, even though they are just feeder fish. When I got home, I put them in a small rubermaid tub, cleaned the tank thoroughly, put in new gravel and filter media, put in freash water conditioned with prime and put the fish back in. They do look more comfortable but look really rough. They are eating but not very much. I don't know how to treat the patches where they are missing scales as I don't know what is causing this. Any information and suggestions would be appreciated. They looked a bit better this morning so I guess the clean water has been somewhat helpful so far. I just think that they must be in pain and suffering.
