Thanks everyone. 
To be fair, even researchers can't tell shadow and regular rock bass apart sometimes.
I'm convinced where the ranges overlap they kind of just guess...
The only reason I know these are shadow bass is rock bass aren't found in my area.
lol^
Love your school of gars.
I can barely tell the difference between my rock bass and your shadow bass. Might have to do with me being new to this family of sunfish
If you ever want any rocks, let me know! I'd be willing to mail it out to ya.
