This may seem a silly question but bear with me as I've kept Rams & Apistos before but never Discus. Can Dwarf Cichlids (Rams & Apistos) be kept in the same tank as Discus? I'm currently planning a four foot tank (approx 75G) and I was thinking it would be really cool to have a small group (1M + 1-2F) of maybe one or two of the following species to liven up the bottom of the tank: Blue Rams, Bolivian Rams, Apisto. Trifasciata, Apisto Borellii or Apisto Cacatuoides.
