Advertisement I have 1.1 Damon diadema, siblings, and I am considering breeding them. I don't know if their parents were related...I am somewhat hesitant, I would rather breed unrelated individuals, but the captive-bred gene pool of D. diadema is rather shallow at present. I sold my other male to someone who has two (presumably unrelated) females. There have been several matings, and I am entitled to a proportion of the offspring, so I may just wait a couple of years and breed one or more of those to my current specimens. Any thoughts?
