Also wanted to add... have you ever tried feeding frozen/thawed (not freeze-dried) bloodworms to your bettas? They are very nutritious for them, and are less constipation (to sbd prone bettas)... one fat/juicy bloodworm = 1 betta pellet (so feed in lieu of a couple of pellets, not in addition to). I feed them at the p.m. feeding virtually every day. It's good that you presoak the pellets too!
