I got this betta from Petco 3 months ago and he's a bottom feeder. It's the weirdest thing, I had him in a 7 with 2 corys, and he would only eat their food (shrimp pellets) that I fed them every few days. Now after 3 months, he's in a 2 with 1 cory, and he still only eats what he finds on the floor, betta pellets that have sunk or cory food. What the heck? Am I doing something wrong! Anyone else have this problem? I just want to make sure that he's getting the right nutrients!
