Yes. But make sure the pieces are cut to about the size of brine shrimp. Make sure you give him one piece at a time. Bettas are slow eaters, plus you won't have a bunch of uneaten food to scoop out if he doesn't like it.i was just wondering because i need more variety in my betta's diet can i feed it frozen tilapia and grocery style shrimp right now i feed him just some pellets and freeze dried brine shrimp. Thanks!
