White flat snails

[adacaro]

It was night time I got up looked at my tank and on one of my corals I sae some white looking things like snails but flat with antennas and some black eggs. I got my turkey baster and sucked about 9 of them and all the eggs. No wounder that coral looked kind of sad. What are they

Sounds like it could be a parasitic nudibranc. Any chance of posting a pic? It's otherwise a guessing game without a visual aid.

I just had the same problem with a Finger Leather Coral.--- Very weird---. I thought it was going to die before I found it.
One of my snails disappeared from its shell and I just figured thats what it was trying to live on the coral (and killing it at the same time).
Keep a close eye on it and look for white hardening areas.
Hopefully you can get some pictures of them posted, if you find some more! That way someone can let us know what they are.

Good luck,
Jason
