Baby Sunfish

Hard to tell, Noto. (about the lateral line)
It does have a larger/rounder profile than most Elassoma species. That's why I was leaning more toward Enneacanthus Gloriosus. It is unusually small for a Bluespot even at 1-1.5 years old...though, I know it takes them about 2 years to sexually mature. It does have a rather large eye for it's size, as well...making me think it is still a juvenile. I wish I could get a better closeup shot of it.
 
I feed my guys once a day M-F and let them fast on weekends. At this age it's not really possible to overfeed. I bet he'll love guppy fry and juvenile shrimp; scuds, daphnia, bllodworms, and blackworms are great live foods too.

Your fish looks like either a bluegill or a redbreast. Is the pectoral fan-like or long and pointed? Either way, he's gonna be a good-sized fish someday; those are two of the biggest sunnies.
 
I wish I knew those groups a little better, Slappy. It's hard for me to ID those fish on sight. But if you posted those pics over at the NANFA board, I bet those guys could give you a positive ID.

Chef- if you're looking to collect fish from the wild, there are a few precautions you can take to improve survivorship: Use a light-colored bucket or a cooler, to keep water temp down; keep the bucket oxygenated with a battery-powered air pump; add a small handful of salt or a squirt of Bait-saver to the water in the bucket before putting the fish in; don't collect when the air temp is high. You may still lose some fish, but mortality will be much reduced. Of course also be sure to know and obey all applicable regulations.
 
Cute little sunfish.
 
try ghost shrimp, too. I used to have a rock bass that would eat so many of them at once that it would rest on the bottom for the rest of the day, lol! River shrimp work really well, too, but they're very hard to keep as they die quickly without a fast current.
