I am just passing on the MAXIMUM size of the rock bass, they seldom get that big and 10" is much closer to average. The small moth reaches 28" and the large mouth reaches 37" but I have never seen them that large myself. The maximum size on a bluegill exceeds 16" but you rarely see them bigger than 12".
This one is not the Green sunfish (Lepomis cyanellus), it is a bit smaller and lives further east.
