I got a new Betta the other day, and when I feed him he tries to bite the pellets but they're too big for him and he just lets them drop to the bottom of the 1g he's in (just for now- I also clean them up off the bottom). Feeling bad for him, I've been giving him Daphnia from a Betta Dial-A-Treat and he eats that up like I've never seen. He also likes the Mysis if it's been cut up a little. I've tried crushing the pellets but he just ignores them.
Is it okay for me to just feed him the Daphnia and Mysis until he gets bigger, or should I try flakes or keep reinforcing the pellets?
