Marine Slugs

[richards]

Hi.

I am new to this hobby and have just set up a 250 ltr aquarium. At the moment I just have live rock in it but have some small cretures that look like slugs coming out of the rock. I need to know if they are harmfull before I place anything else into the aquarium. They are about 1" long greenish grey in colour with about 1/2 of the body covered by an oval soft looking shell. They climb glass and graze on the rocks. Any help will be much apriciated.

Many Thanks.

Richard

Have a look on here

Could be Sheild Limpets or chitons- I have noticed some of these on my LR recently

Sounds more like Stomeatella snails to me. These are slug shaped dreatures with a shell shaped like a fingernail. They can move pretty fast for a snail too!

If its a stomatella snail then there is no need for concern as they are great additions to the cleanup crew,

ewww I have been so jelous of the marine tanks lately I love all the shrimp, and your pics of the rock coming to life. I am officially cured for the time after seeing that water spider. Made my skin crawl.
