Nope, and looking at your current tank setup list I'm not suprised you give such bad advice.
Pair of Firemouths + 1 other fish that can handle themselves in that sized tank, maybe a Salvini, Blue Acara, or Severum. Perhaps even a JD but that's getting a little on the larger side of what you'd want in there.
