I am already on NANFA....way long time ago before I came to this site.MN_Rebel, how come you aren't on NANFA?
^ I would forget about sauger, they are horrible display fish. Never moves during day or while the light is on. Prefers feeding under the dark time and live foods only. And they prefer to hides and just stay there till the dark. A 75gal may not be ideal for a bullhead, depends on what species but it will outgrew the 75gal eventually. So are rock bass, they get larger than sunfish species so I don't think a 75gal is ideal for a rock bass either.
I'm not a fan of Oscars.
get a black or large mouth bass then or perhaps a sun fish, not a blue gill. both natives, as for I do not like oscars?![]()
