Lol that sounds like Leo! He loves to eat...he even sometimes makes a snack out my friends goldfish's "sun dried baby shrimp" (she had put a couple in a plastic bag and gave them to me, thinking he might like them). I give them to him as a treat and it keeps him busy, takes him a bit to tear it apart lol. They are pretty small though, perfect betta size. He also gets pellets, omega one flakes and the bloodworms. I try to change up his diet so he doesn't get bored lol. Toby loves his pellets though he is not too keen on the flakes yet...he'll get there lol.
I have a feeling that betta fish are some of the most spoiled fish around! Not that there is anything wrong with that haha- in fact I love to spoil my boys.
