Im keeping them now, Got them from Rob @ Keystone Aquatics, A killer fish, Kind like a Red Trimac without the A***ole, I had a group of three in a 75 and they told me (All Males) who was staying and who was going. Mine can be aggressive with a size advantage, but when they are dealing with the same size or bigger, wilt under the pressure. I keep mine with a Gold Saum, Silver Saum, Port, Bartoni, and a Pair of Cutteri, he runs the tank.....Ill have to get some shots, my guy is still a juvi (3.5") and the reds are starting to come out! You could start in a 55 gallon, but a 75 is ideal for a pair. Im enjoying the personality and looks (minus the Green) of a trimac, who is not ripping off heads. Had him for about 4 months and he is about 4", got him really small, I'd say 3/4" a month.
Ill get some shots and get them up tomorrow........
