Well, what would YOU say?
Cyanoacrylate adhesives AKA "superglue", routinely used medically/surgically to seal/attach.
Heck!!!
My face, sliced open during an incident where a ladder gave way and I crashed headlong INTO ROW OF MARINE TANKS.
In surgery, I insisted I HAD to make a few PHOTOSHOOTS that SAME WEEK!!
Was offered patch-up with "medical grade"...superglue!!!
Sufficeth to say- I made my appointed 'shoots, appeared in YOU/HuisGenoot and Cape Times/Argus those next 2weeks.
THAT lot of words, was just to demonstrate it's safety aspect, EXCEPT if you find yourself STUCK some ridiculous way...
I/many others regularly use superglue for coral fragment attachment, and this includes zoanthus/palythoa types.
Just use a dab or two, on dried tissue, attach with firm pressure to surface required ...and release...within 1min most will adhere.
If it doesn't TAKE, just redry, redo..
NO MESS NO FUSS!! :clover:
BTW YOUR skimmer/carbon will remove minor residual compounds from your glueing efforts....
Perfectly safe, acceptable in Reef Tank environments
HTH
