Electric Bullhead?

Just an update. About a month later, this behavior stopped. Never any aggression between the 2.

Both Spotted Bullheads and Florida Browns are really neat aquarium species to own, most bullheads have poisonous spines.....was the Bullhead sticking the Smallmouth before the "territorial aggression" dance?

+1 both beautiful fish. And yes bullheads have mildly poisonous spines but try getting sticked by a Madtom, their spines are basically toxin laced needles!

No, when this occurred, when they were first introduced, it was just the bullhead "feeling" its way around its new surrounding and every so often would light brush up to the smb with its whiskers, and some times there wasn't even contact, just proximity, that would trigger this shaking. The bullhead still occassionally would brush up against the smb (and the lmb as well) and there is no longer the shaking. Its now treated with indifference.
