Oh yeah, it's a 125g.
The bullhead will have to be moved to a bigger tank eventually since he'll hit 16 inches or more, he's already eaten a couple of fish at 7 inches, and likely the bass, though spotteds often don't get as big as normal largemouth.
Right now they're all juveniles, or at least not full size, except for the madtom and a couple of the longear.
