Hello- I would not recommend this practice. I had tried it once and had disasterous results. However, this is not a absolute. Some have had success keeping different species and same species in multi-enclosures. If you do try this be vigilant and be ready to separate cagemates.
:Hi, :Can u house two different breeds of uros together? Cuz we have a male orange niger now, but we love the ornates too so we want to know if u can put them together, as long as we get a female. Thanx.
