I got this the other day at the LFS
, and the guy told me that it was a purple sea slug, and that it was an algae eater.
Last night before I went to bed, he was all wrapped up in a spiral on the glass.
When I got up this morning, this was in his place, and he had moved to another location in the tank and has not moved since.
This website has a similar picture and calls it "Purple Nudibranch and Eggs" Are these eggs??
I read that nudibranch eat hydroids. What are those?
Thanks, there should be two pics. One of the critter, and one of the spiral of unknown stuff.
