Just a couple of questions out of interest (not intending to get one, although the questions suggest otherwise...)
How big a tank do they need (in terms of dimensions)? Because most places say 36", but convicts and rainbow cichlids are often recommended in 30" (or even 24")
How aggressive are they?
Thanks.
