Things like dovii, festae and jags get big enough to where your front to back length is too small for them. Like I said, we have "small" tanks that can't keep all the fish we want ='(
Beleive GT could work but there may be those who disagree. Can't say for the Mayan, I don't know much about them. There are other cichlids that could work but aren't listed here. I'd suggest continue to research and find what you like since you have time before you'd like to move your FH out.
Always a work in progress. It has to wait but my next tank will be either a 75 (if we stay in a small apartment) or a 125 (if we choose a house). For now I have to work with my 37 and 55 gallons.
