i was asking for compatibility for the fish and i get all of this instead, if a texas or an oscar aren't for a 55 gallon then why do a lot of people keep an oscar or a texas in a 55 gallon? and why does this site say an oscar is for a 55 gallon?Then why ask other members for advice if you already have your mind set on doing things your way? You've been told by several members that a 55 is inadequate for the fish that you are interested in, yet you are still planning to do it anyway. If you can't get a 75 or larger tank, don't get fish that requires one. But do as you see fit.

and i said i'll look for a 75 gallon and my parents will probably change their mind, a 75 gallon is simply wider than a 55, now are senegal bichirs compatible with texas cichlid and can a pair of texas be put in a 75? 75 gallons is better anyways
