Hello, I noticed in my tank some yellow "slugs" (I think) on the glass. Now there seems more of them then before. They look like yellow logs with two large atennae. I'd like to know what they are and if they are reef safe? Sorry for the quality of the photo

It seems to be a species of Elysia. If you want to see some variety, have a look at the Species List for photos and information on a numnber of different species of Elysia. They are herbivores which have probably hitched a ride on some green algae or an algal covered rock. They may not survive in your aquaria but I can't imagine them doing any harm.
