So a few days ago on Sunday I posted that my betta was sick. He was bloated and flopping around the tank side ways. After not eating for two days, he isn't flopping anymore, but he still looks terrible. He swims around the perimeter of the tank occasionally (normal swimming), but then goes back to hiding behind the filter. It looks like his face is peeling off as well. He is not as bloated as he was before, but he looks worse, and I don't know what to do. Earlier, people said that I was feeding him the wrong stuff (frozen blood worms everyday, when it shouldn't have been doing that), but is it too late for him? Ever since I got him seven months ago, he had these weird bloated poos, but he hasn't had one recently, and for the last few weeks, he has been losing color and slowing getting very sluggish. Water temp is 78, and he gets weekly water changes of between 25 and 40 percent. I don't know the ammonia or anything like that.
