Vieja bifasciatum if you wanna do something different, always wanted one so bad. Good luck though.
A good JD breeder tank is fantastic though, mine ignore synodont cats if you'd like to add those as tank mates. Firemouths work well to, but when spawning time comes, problems will arise.
out of all of these, red tiger mota and carpintis are better looking cichlids. RTM stay around 1 foot, similar to jaguar cichlid, but smaller and have red/gold on their body.
Carpintis have very pretty spots, but hard to find in lfs, texas cichlid cyano can be found in almost every petstore, they have tiny spots and cheaper.
my first thought was Blue Acara . . . I would have thought any "Texas" varieties (cyanoguttatus or carpinte) would get too big, but the more I think about it, the more I like the idea; personally, I prefer the carpinte, which I believe also remains a bit smaller . . .
the only thing I'll say about salvini is that IME, the males can be very rough . . .
