180 or 220.. 2 oscars and a JD... you could try some of the more oddball Ca/SA cichlids out there as suggested.. not a big cichlid fan so i'm not gonna have the best options.. but some of the pike cichlids may be worth looking into, attractive and not as popular as alot of other species out there.. for catfish, i always suggest synos with cichlids. they simply do well and there are alot to chose from and again oddball enough but not gonna break the bank either, and hearty. you could also try something like a favrus tire track eel, or black leopard eel. both will get 24" give or take and are aggressive enough to hold their own with cichlids ime.
