you might want a brakish or marine list too, Somewhere to put the Pufferfish and the Jacks (Ulua here in Hawaii). Not a typical aquarium fish but a barracuda even the babies are 100% predator, smart too.
My 2 male red devils, trimac, 2 flowerhorns and 3 midas are the most aggressive cichlids that i ever kept. They have killed 3 oscars, 17 green terrors, jack dempsy, salvini, firemouth, pacu, 3 id sharks and texas cichlid.
