Im planing a new hight tech 100g planted tank with a 50g sump. Ive kept fish off and on since i was a kid, my current tanks for the last 5 yrs but never kept dwarf cichlids or apistos before. im planning on a community tank with smaller peaceful fish and want to include either GBR or bolivian rams and cockatoo apsitos or other apistos.

If my tank has a 150cm x 50cm footprint what would be my stocking limits and could i mix species. Also if my vhoices would work well what would be some other options. Thanx
