Yes, just don't do anything stupid, like get a Giant Gourami, or a puffer fish. I would suggest a tri-spotted/blue gourami. I have two 4 inchers in my 100G.
i would suggest honey gouramis. Or maybe some dwarf gouramis. I think the yellow and blues might be too mean in a 29. I had a yellow that killed all my fish in my 29, even giant danios (surprised it could catch them).
