I currently have a baby blue gill that i've had since it was about a 1/4" fry. hes about 2 now and is a character, i started with three but one was a nutter and the other died. they seem to like the warmer water, i caught him with an aquarium net out of some algae. He is probably the funnest fish i've ever owned he will eat anything and when someone walks my tropical cichlids usually hide and he is at the surface waiting to see what the friendly humans brought to feed him haha. gets it from his parents since he was in a residential pond where people just walk up and throw in worms and bread to watch them eat. i plan on keeping him until he passes because he's probably my favorite fish. he tried to take down a whole earthworm and did take down two rosy red feeders in one day (keep in mind he is only two inches or so haha) the feeders weren't meant for him but he ate them. haha enough ramblin on about my beloved bluegill lol
