Crushing works like a charm for me.
Crushing also worked for me. My betta has been able to eat again. See she was not able to eat because she could not get the whole pellet in her mouth. She could get it in there part of the way but then she had to spit it back out. She could not take it in her mouth all the way. So I have tried crushing them up and it has worked wonders for me. It will be able to let her eat until Friday. I go shopping on Friday. I will be able to get her some betta fish flakes. If you don't have enough money or you don't have enough time you can just crush them up, and When you get time and have the money you can go get some of the fish flakes.
