My betta Otus was purchased about 2 weeks ago at petsmart (terrible place to get fish I have found) he has been lively, active, aggressive, everything a betta should be until yesterday. I had bought some algea pellet things for my corydoras, and dropped one in there. Otus ate most of it. His belly got really big, then today his coloring was very dull. I'm not sure if it was the pellets that made him sick/was bad for him? He's been really slow today and has a big ol' belly. He is soooo pale compared to normal. I noticed this when I switched them all into a new tank. (3 corydoras, 2 snails, 1 betta) Anyways...could it have been the algea? If so, is there a way to keep him from eating it, but allowing the corydoras to eat? I am worried about him! Much thanks!!
