I went to check on my sisters betta today, and noticed something that looked like a huge piece of poop on top of one of his decorations. It was poop, Im pretty sure. But it was like the size of two grains of rice balled up into one! I almost never see Piccolo's feces, so thats how I know something is very wrong. The fish I was talking about, dubbed Mr. Mia, has a bit of.... problems, that I should tell you. First of all, his tank isnt cleaned enough. I nag her about that and it is getting cleaned more now. He has a bad case of fin rot/melt, but it is getting better eith the cleanings. He is a male HM in a 2 gal tank. One side of is body is much duller than the other. He has no tankmates. He eats pellets, bloodworms, and occasional flakes. And this is my sisters fish, not mine. I will post pictures soon. Any tips about these problems will help immensely.
