Fabulous fish from Madagascar, can get to 12", and if in a community setting (as stated above) they can get quite aggressive if the tank is under 100 gallons.
I find although moderately aggressive, they are not able to compete with seriously aggressive North or Central Americans like the Herichthys carpintus clade.
The alpha males can be quite aggressive with, and often kill subordinate males and females at maturity in anything under a 6ft tank.
Mine devour any pellet, shell-less invertebrate or insect small enough to swallow. And although they are really not piscavores, will eat any fish they can fit in their cavernous mouth, given the opportunity.

male above female below, although I have seen what I thought was a female, grow a hump and increase in size almost over night, when the alpha was removed from the tank.

the video below is in a 6ft tank
