I've got three of these little guys in my 5 foot planted tank, they're not very personable but incredibly entertaining to watch as they're quite aggressive towards each other but never do any damage, lot of flaring and ramming but it's almost like it's all in good fun.
What I mean by not very personable is in my experience they are not remotely interested in what's going on outside the tank, and never come to the surface waiting for food like Blue Rams do, I feed sinking pellets and my guys go to down on them as soon as they sink down to them, but are never eager to eat.
