I don't think it's a lettuce nudi, but it is some type of nudi. Can you get a better picture of it? Do you have a refugium you can put it in and observe it?
no thats the best pic i could get. he is REALLY small , about the size of the lead on a pencil
. he moves like a inch worm. he went from one zoo rock to another and back again so i was afraid he was one of the ones that eat zoos and removed him.
