Looks to just be superglue. I have heard of reef poxy when used too much or over handled can effect oxygen and pH but never heard of a problem with superglue.
Did you use any coral dip on the frags? Some of those can be pretty harsh if not rinsed properly but would have probably took out the fish too.
Maybe sick fish and working in the tank gluing down frags was enough stress to push them over... idk...
