I'm having a hard time telling different sunfish species apart.  A lot of them seem really similar.  Can I get an ID on this one?  I know its not the best pic.

 

 

redbreast sunfish?

Really hard to tell without a close up of the fish and with a lot of it covered up. I'd say it's either a redbreast or pumpkinseed.

Pumpkinseed would be my guess. We have a ton of stunted little ones like that in my lake that vary from really dark to the brighter shades of orange/blue.

The lake/spillway is actually located at a fish hatchery and I found a website that lists the fish species.  It only lists 3 sunfish.  Bluegill, pumpkinseed, and green sunfish so I'm assuming it would be one of these.  Being that its a fish hatchery, I would think they know what's in their waters.

Looks like a pumpkinseed, from the photos it appears to have blue iridescent streaks near the mouth.

Small redbreast......
