Love both of these ideas and am leaning towards you suggestion on the green Terror. Ideally what would the numbers on this kind of stock look like in your opinion if you chose them yourself?I would stock with fish from West of the Andes mts, think Peru, Ecuador or Central America's.
You could go with Andinoacara Rivilatus-Green terror or Andinoacara Pulcher-Blue Acara as the main cichlids. The Terrors are bigger and as the name implies more aggressive. The Acara are much smaller and know to do well in a community tank. Tho the males are known to bite into a plant and shake it as part of the breeding/bonding process so may get some plant damage.
Get a nice group of tetras twenty or more Columbian, Bleeding Hearts etc to occupie the mid lvl of the tank.
A group of 6 or more Cory cats if going with Acara or Hoplo cats or a Pimelodus Ornatus if going with Terrors.
Could get some Pink tailed Chalceus for the surface area of the tank.
I’m assuming the green terror would be the last fish introduced to the tank as well.
White sand a couple large pieces of driftwood and some plants specific to their habitat?
