My black and white ocellaris pairs started spawning at 1.5 - 2 years of age. I don't know if anyone has established longevity for these, but it's probably similar to regular ocellaris. I have several pairs that are going on 16 years now, and still spawning. There are numreous reports of 20+ years. In about a month I should have an article complete about conditioning these and larval rearing, complete with lot's of pics.
