I was wondering if anyone had tried Ruby Greens Mbuna such as the Yellow Labs, Blue Cobalt, Acei or Saulosi. I am trying to plan out the upgrade of 2 of my tanks, but need some advice on what I can put with my Ruby Greens. I am pretty sure that mixing a Mbuna species with the Ruby Greens is probably an awful idea, but I thought I would ask. Stranger things have occurred.
