I'm planning to set up a new 6', 125 gallon aquarium predominately with American Cichlids such as Severums, Firemouth, Convict, Blue Acara, and one or two of the smaller Geophagus, in addition to a couple of Ancistrus, and some Blue Columbian Tetras or Giant Danios as dither fish. As far as the catfish go can I put Adolphi Corydoras in with this mix or can someone suggest catfish to use.
