hit it pretty good. Archers are awesome and do well when the tank is full. If you want other oddball fish here are a few others that stand out to me don't keep them together: Jelly catfish, Shoehead catfish, Blue Dolphin catfish, Celebes Halfbeaks, bluehead chub, round gobies, rainbow gudgeon (Giuris margaritacea), or Uaru not really an oddball, but still a cool fish.
