It's been awhile since I found something in one of my tanks that I can't ID. I found this little one today hitching a ride on the back of a snails shell. I would NEVER have seen him in my green macro forest. Could it be a baby lettuce nudi? Do they reproduce in the home aquariums? Or is it something else? Any ideas?
There are NO corals in this tank, only macros, live rock and sand, snails, micro hermits, and of course my seahorses.
