Im a little embarrassed, but i was gluing the other day, got a little glue on my finger, which of course I inadvertently used to touch my tongue and lip. It was very annoying to have IC Gel on my tongue but by the end of the day, I couldn't tell that it was ever there.
So based upon my personal experience, Im going to guess the glue on the fish will likely come off in a day or two.
I had this happen to my foxface. Luckily he eats out of my hand. I was able to catch him with the swipe of he net at the water surface, and then I performed glue removal surgery Everything was fine
