Rock Bass (Ambloplites rupestris)
Don't confuse a passionate red stare and a fiery personality for wickedness. A member of the sunfish family, this species is a lively contender when hooked by fishermen and a fierce competitor of smallmouth bass for breakfast (aquatic insects and other fish). During spawning season, male rock bass dig nests in the substrate in shallow water; when nests become too numerous, which is bound to happen, they lash out in turf wars and brawls over females. Peace-loving folks may call this fish a little too defensive or maybe a titch aggressive, but even a small rock bass can cop a large attitude.
