Some hatchets would look nice and the more common silver hatchets get a decent size. If you are interested in another cichlid, Mesonauta Insignus is the most colorful festivum. A final option would be some pink tailed Chalceus or some Boulengerella or Hujeta gars. I keep them with my discus and altums.Thanks! Ive thought about it, but nothing so far has piqued my interest Im also pretty happy with having only 4 species, but the top 2/3rds of tank goes unused. Any recommendations?
