I have 2 young pickerel in a tank together and i was thinking that they were both redfin/grass pickerel. After looking at the larger one though, which is probably around 2 in, I'm starting to think that it isnt actually a redfin. It has the tall bars but doesnt have the deep green coloring that most have. Instead, it is more of a pale green and olive. Anyways, does anyone have any pictures of young grass, redfin, and chain pickerel that they know for sure what they are? Maybe, a side-by-side that shows the differences in the two because i have read that the chains dont actually get the "chain" pattern until they are older. I will try to get pictures up soon but thanks for the help in advance.

Here are the pictures of the pickerel im unsure about. Can anyone ID it for me? Thanks.

Heh, looks like a chain's head on a grass's body. Can you get a shot of the underside of the head/throat area? There is a fairly good distinction in the number of branchiostegal rays.

That is pretty distinctly a chain pickerel, although as Newt said, it does have the patterning of a grass/redfin. Definately a chain based on the head shape.
