I'm having a problem feeding one of my bettas. He can't seem to keep pellets down! He wants to eat them, and he usually manages to eat one, but after that he starts to spit them out. He eats the pellets, seems to have trouble swallowing, and then spits it out. I'm currently feeding him the nutrafin pellets, but I'm wondering if there's any smaller type of pellet that's available.
Thankfully, he's still eating freeze dried bloodworms, but I don't want to always feed him those. I want to give him some variety.
