hi everyone i am new to this site, but i have kept a tropical 10 gallon fish tank for five years and i recently converted to a native tank with creek chubs in it. I am getting into native fish and i am thinking of putting one largemouth bass (preferably a male because they r smaller. (not quite sure how to tell gender though, help with that would be appreciated) and maybe some other smaller sunfish. There is a stream in my backyard where i can get an unlimited supply of creek chubs for the bass's food. The chubs go from 1 inch to 1 foot; ill up the food size as the bass grows. I am planning on a 150-180 gallon tank which should be fine at room temp. Any advice on tank size, filtration, companions, how to tell a fishes gender, and anything else is greatly appreciated.
