I have noticed my largemouth and smallmouth pair (each IN a 125 gallon fish tank) spawn on large flat rocks v.s. rounded stone pits like sunfish ive had- the smallmouth clutches are much smaller and the largemouth like a rock that is like a shallow bowl. The fry are protected vigorously. My largemouth male will attack my hand but my smallmouth doesnt care if i have a crayfish for him.
