Hi, My betta has been floating at the top of his tank for a few days now. It keeps happening after I feed him only one betta pellet. I have been fasting him then feeding him a small piece of a pea and within the day he is usually back to normal and swimming. But yesterday I fed him a soaked betta pellet and again he has started to float at the top of his tank. I decided I would fast him and try the pea method again but this morning I noticed feces in the bottom of his tank but he is still floating at the top. His tank is at 80 degrees and he is in a smaller tank than his usual 5 gallon tank. I am just unsure of what could be causing this chronic problem and what I should be doing to help him.
