I got one last week. So I probably know even less about it than you.
Mine is about 2' long. It is in a 130g with a 1' black arowana and a 15" motoro. It used to share a 60g with the same motoro before, so it is happier now. It eats tetra-sticks of the surface, and it eats loads of them. It is seems very docile and passive, more active in the evening.
