Identify this Guy from my live rock

[Martin Cox]

Hi All First Post So Go Easy!!

I have added some live rock to my new saltwater tank today, after a few hours the little guy pictured arrived on my tank glass,

He is kind of a slug type creature, with a lime and black "shell" although in not sure its hard, Hes got tenticles as long as his body.

Is he safe?
Any ideas what he is?
Is it ok to leave him in there or get him out?

Any help is greatly appreciated, Thanks in Advance.

PS Sorry about the size of the attachment..... Its kind of a spot him if you can photo!

Obviously an invertebrate. Take a look at the description of this forum. For invert questions, you'll want to post in the Reef Forum.

Although a snail in appearance, this is not a snail. These guys spread pretty quickly, but that is all I know.

hi Rogerreef here, I have exactly the same type of snail in my tank, He only comes out in the evening and grazes on the rock. I think he is harmless so enjoy having him as a clean up crew
