Yes, looking for 'swimming' fish, not fussy on region.
Some Banded Leopornius could work, as for big brutes there are Red Star Flowerhorn Cichlids, Peacock Bass, Uaru Cichlid, Electric Blue Jack Dempsey (all jack's work), Green Terror, Cornish Jack, or a Pink Tail Chalceus would look nice
Uarus, aren't aggressive and he already has some in another tank and the tank is to small for most leporinus, peacock bass and cornish jacks. It's only 90 gallons roughly.
Come on Crossfire, I thought you spent all your free time here.
What are the exact dimensions of the tank? That would help with ideas. Do you want a community or are you ok with just one fish?
