Ex: Massivore/pellet foods contains vitamins. Reason I ask is because Massivore (don't mean to bash on Hikari) smells awful like poo but they will eat them. And I saw my bichir try to eat its own poo, I feed them once a day until they have stomach with slight bulges and they poop it out within the next day so it couldn't have been that they were starving to eat the poo. So would anyone with experience here know if they would be okay eating tilapia/shrimp as a staple which provides the necessary vitamins/nutrients needed? I have obtained other pellet foods on amazon with multivitamins that don't smell like poo but they aren't that smelly and are pretty hard to break apart so i'm not sure if they have been stored for too long of a time period. I guess I would be asking anyone here who is a marine/fish dietitian (unlikely I guess lol) or more likely has anyone here kept bichirs for years and grown healthy on a staple of tilapia/shrimp?
