I got a 175 sitting empty in the garage. I'm setting it up as soon as I can get the 150 sold. I've never kept SA/CA cichlids long enough to know their behavior. My wife has always wanted a Blood Parrot and Oscars but also wants a Clown Knife. I just want a senegal poly. Could all these get along in a 175. Dems are 72"Lx20"Wx28"T. I'll have sand and a few XXL pieces of driftwood. Also, my wife wants big pretty fish. She likes the Green Terror and Red Terrors. Could we have those too? I'm looking for suggestions for big pretty fish and large oddballs.
