Lisa, I am learning that the hard way.....I know those shrimp are small, but geez I am finding it nearly impossible to see them in my tank. And, he is chasing them around badly! I fear he has probably eaten some of the smaller ones already . I so wanted to be able to watch those cute little shrimp. I am beginning to get a little aggravated with my betta because he is being ugly to everyone I put in there. I gave him this nice 10g home and he can't be nice enough to share happily....ggrrrrr.
