its a green sunfish for sure i had a blue gill for 6 years and they dont develop a circle like shape until they get really big when bluegills are that size they look more like dull electric blue cichilds they also have different markings
So what do you guys feed your Green's? I tried a pellet lastnight but it spit it out. He is eating earthworms like crazy. He's a little guy so I'm only giving him one a night. He attacks them though!
