So Martin is my black rimmed mustard halfmoon betta, and I just figured out something. He is probably the most picky eater in all of betta history. The only thing he will eat is frozen-thawed brine shrimp. I've tried all the the flake and pellet foods, but he just ignores them. I have yet to try frozen-thawed bloodworms though. Will he be ok eating just frozen-thawed brine shrimp? The only reason I'm worried is because I don't know if he will get all the nutrition he needs in just brine shrimp.
