Common mistakes

Fishing open, featureless bottom instead of tight to the boulders, logs, and vegetation beds where rock bass actually hold.
Only fishing during daylight hours; rock bass feed most actively at dawn, dusk, and after dark.
Assuming an aggressive topwater strike must be a bass; rock bass will hit lures nearly as large as themselves.
