Im gonna get flamed, but WTF...
You CAN do all species of Parachromis,(minus the Dovii) as long as they were raised together. I have seen it done and have done it myself. I currently have a 220 (6' x 24" x 30") with:
2x-Motas (Red Tigers)
1x-Jag
2x-Loiselle
2x-Cubans
2x-Carpinte (Escondido)
1x-Grammode
1x-Salvini
3x-M-Cons
With Sliver Dollars for Dithers, 1x-Butterfly Pleco, 1x-Leopard Pleco, 1x Albino Bristlenose, 1x-Red Striped Raphael, and 2x
-Botia berdmorei
.
Look to Repairs 265 for guideance, he has helped me many time over the past years and has the tank to prove it. Barred Midas, Uro, Jags, Midas of all sorts, Red Devils, Vieja... etc... it is a thing of beauty:

My 125 was also what many would call "Overstocked"
1x-Jag
1x-Mota
1x-Uro
1x-Carpinte
1x-HRP Male
3x-Con Male
1x-Red Devil
with 1x-Pictus Cat, 1x-Rubberlip Pleco, & 1x-Albino Bristlenose
It can be done, filter the fudge out of it (I have a 10x turnover) or be prepared to do a wet-dry or Drip....
Ill be honest, Im selling all of my canisters and having Repair and Rally install a wet-dry to run my 220 and 150 side by side. It can be done.
