add some RTC's, Silver Aros, 2 arapaimas, that would be good. Jus playin, If youve started with cichlids, i would suggest just add more cichlids, i like to make my tanks with "themes" so if south american cichlids are placed, i would only put fish from that area, if tetras, then all tetras, you see where im coming at? make it look as natural as possible, well thats just me. Good luck
