I've got a 55 gal tank indoors with 4 - 3-4" goldfish. They are about 3-4 years old.
I'm just coming off a medication cycle for fin rot and suddenly one of them is exhibiting strange bahavoir. He/she will sit on the bottom and I think I'm losing him, then he will be swimming around, but won;t eat, and suddenly stops swimming and just float motionelss around. This goes on the 2-3 minutes and suddenly he will take off swimming straight down and crash into the bottom. He will bump/rub his mouth sometime sturning over on his back then stop and start swimming somewhat normally. I can see no evidence of parasites, ick or anything else abnormal. They are all recovering from fin rot after the 2nd treatment.
What the heck is wrong?
:help:
