My adult spawning pair will come up front for food, but they are not gregariously tame like oscars.
They are lurk and strike predators, that sit and wait, and do a lightning strike when prey comes near.
I've been able to keep them with other large, dissimilar looking cichlids without aggression problems.
The pair are now alone in a 75 gal, small fish like tetras quickly disappear.
and my fry are growing out in a 55 with Herichthys bartoni, and some others with young Ctenochromis horei.
