Although I have no experience with saltwater fry....there is one thing I do know, and that is to not expose them to air! If you decide to move them, then gently scooping them up in a small bowl or cup would be the best way to do it.
Again, I'm no expert, but it would seem to me that as long as they can't be sucked out of the refugium, that it might be best to leave them there to feed on whatever may be living in there. Newly
hatched brine shrimp is good,
maybe some DT's might help too.....hard to say since you don't know what they are.....
Good luck! And congratulations too!!
