I just got a betta fish from petco that is about an inch or so but i also have a rapidly growing oscar fish that i feed these Hikari Cichlid pellets to. Instead of buying more food for the betta i was curious if i could feed the Hikari pellets to my betta fish without causing any harm to it. Also in case you didn't notice in the title these are the mini pellet size if you are familiar with this brand of cichlid food.
