Ok guys, I just found out that the black rhom I bought two months ago may in fact be a S. Altuvei. I have heard practically nothing about this species and would like some input. I will also read the factsheet but I would like some live experience also. Also what is the major difference between rhom and altuvei, what about size diff, aggression, which is more expensive, rare, what about feeding habits, tank size, and light requirements. And overall, which is the better fish to have? Thanks again guys!
