20 gal is decent for a pair, but a 30 would be better, but not necessary. I'd suggest no tankmates either in the 20 gal. Theyre smaller cichlids that reach about 4-6 inch, the male being the larger one. Females have a orange/red belly and it gets a brick red color when they are gonna mate. They will eat pellets, bloodworms and all types of foods, guppies too.
For filtration on a 20 gal you dont need to go overboard. Maybe a Penguin/marinland 350 would be good. You can even go less than that too. Make sure to do weekly water changes. Thats pretty much it.

Atleast thats the excuse that worked with my wife.
