As some of you may know i resently got a 75gallon fish tank that i would like to keep natives in. i would like to have some rock bass and sunfish in it and then a larger "show" fish. i was thinking a grass/redfin pickerel but the availability and price (im not the one to pay 30 for a fish) of these fish are not making it likely. so i was wondering what kind of fish should get that would be bigger than the rest of my fish but still beble to live in a 75 for life? also what would be a good bottom dweller? i was thinking bullhead but i hear they are not good.
