I've kept my Betta fish, Atlas, for a little over five months now, and have not had any problems aside from a bout of fin rot early on. Recently, I have moved my Betta fish from a gallon sized bowl to a 2.5 gallon Fluval tank. The idea was to have a filter finally, but I do realize that the filter on this tank is too strong for my fish so I only keep it on about a half hour a day. Anyhow, he was fine the first week he was in the tank, but since I moved back into my college dorm he doesn't eat and he appears to have missing and raised scales. I am concerned about him.
My betta fish has missing and raised scales towards his head. He will not eat. What do I do?
P.S. The tank is complete with a filter, a heater, and a thermometer. Frankly, he's in better conditions now than he was in the gallon sized tank, but appears to be doing worse.
