I have a 150 gallon 6'x2' tank that I would like to stock with a group of Xenos and/or Enantiopus Melanogenys. Would the two compete too much for the sand space? I was thinking Paracyps for the rocky area and top space. What else would work good in this tank? I am partial to Eretmodus though having never kept xenos or enantiopus I dont how they would do. I would like to be able to spawn the groups in the tank so I want to avoid altos and comps. Any suggestions or ecperiences with the above fish wouold be appreciated.
