Who out there has actually bred Damon diadema

[J Morningstar]

Okay then from all the available articles I could get I have heard that I have about 3 to 6 more months before I should really worry about them doing away with each other. Who out there has actually bred them and how many can be kept communally successfully(one per how many square inches of tank are nessasarry). I have lots of space and lots of hides and am making more but I will divide and conqure if I have too. Advice Please.
