I'm planning on upgrading(might as well go big) the tank to give the pair some more room yet I'm undecided on how to fill the space(adding a 55g sump as well). I'd like to have fish from Peru to maintain the biotope feel as I have so far.
So this is my tank at the moment:

Keep in mind that I'm looking for GT tankmates.
My first option would be a Pink Tail Chalceus. Their huge scales look amazing and the pink would definitely pop out in a dark background. They swim up top so I won't have to worry much about aggression. The only thing I would have to do differently is add a lid at the top since they are skittish. I'll probably just put one in, three if I can get away with it.

Second option would be a female Red Terror. The only thing I'm afraid of is their level of aggression and how fast will they outgrow my Green Terrors. It would definitely be a big risk but still reasonable. Opinions?

Third and fourth options would be Geos and Oscar(s) but I'm not really interested on either. I think the Geos would be too fragile while the Oscars don't appeal to me. Still, both are not out of the equation.
I'm still researching into other possibilities and I definitely would like to hear some suggestions! Thanks!
