I see you're interested in mouthless frags and just recently have something to input. I don't recall exactly when, but around 10 months ago I fed a war paint scoly and afterward a crab must have gone after the food. I never saw the event, but afterward I found the scoly completely devoid of a mouth and most of its oral disk. Pretty much all that was left was the outer very fleshy part. I thought it would be a goner but threw it in my sump under t-5's. Within the last couple weeks I have been able to see decent growth and 3 new mouths form. 1/4 of the outer tissue died but the other 3/4 have each grown new mouths and they can be fed. I started this week feeding hikari marine 's'. I am thinking that the growth time for them to become actual scolys will be months more - and tiny ones at that. If you're into a science experiment go ahead, but the turn around time on these mouthless pieces is crazy long.
On a side note, what is the reason you fragged these? I have been thinking about doing it to several others to sell at our frag swaps. I could make small frags, heal them, and sell them cheap so others can enjoy them. I hate the price tag they have so this benefits everyone by having frags(not wild pieces) and cheaper prices locally.
