After my disastorous tank crash last week, I only have a pair of male dwarf gourami's in my 29 gallon tank. Both seem to be very, very shy and don't come out except to feed. I'm wanting to add more fish to the tank to act as dither fish and also be colorful as well. I wouldn't mind an oddball or two but I'm not sure what to get. I've got about 30 tetras in my 55 gallon tank so I don't really want any more of them in the 29 (though I do want more for the 55). Aside from that, I'm not sure what to add. Any suggestions?
