they only come out at night

I took a peek at my tank this morning at 4:30 am noticed 15 pale green little slug like creatures stuck to the front wall. When I turned on the light to get a better look they all took off down the wall and under rocks. Are these likely to be worms, snails with no shells, slugs or baby nudibrachs?

Sounds like a Stomatella snail. I'll try to find a pic for you ;) .

BTW i've seen these guys only 3 times during the day since I started reef'n about a year ago :D .

Are they good to have in your tank?

They are good. They eat diatoms.

[Mak]

Yes, they are good. Sounds like you have a nice sized population.

Hehe I call'em the graveyard shift :D .

I also know of a few fellow reefers, including my self that have these things multiplying like crazy in our tanks.
Lots and lots!
