Okay, say if these were in a 4x2x2 (not all together) with 1 other cichlid, a couple bottom dwellers.
And im talking about their aggression in general, like convicts, there generally aggressive.
Black Belt, Manguanese, Red Terror are probably the most aggressive most of the time, then the Green Terror, Jewel and most Flowerhorns (the rest of the Flowerhorns belong in top group) are little better but more reports of them living in modest tanks. Then Cons, Oscars and JDs are probably the safest bets.
