I'd say get acaras and stuff and other South Americans then. you can always have other fish in there too cause they acclimatise to conditions really well.
Ive got 2 BGK's, various apistos, acaras, bloivian rams, some plecs, heaps of different types of cories (12ish),10 clown loaches, couple of pantadon butterfly's and angels...siamese fighter... etc...etc...
and a cazillion plants, lol...
tank works well
