Sea slug?

[ecko1211]

Found this guy today and was wondering what he is and if he's safe for my tank? I believe he was in the chaeto I got a couple weeks ago so I figure he's a type of sea slug? Keep or not to keep? Thanks guys.

basically in the same family of a sea cucumber. I found one in my macro algea a month or so as well, however mine was much smaller and more clear. they are great detritus cleaners however I decided to remove mine due to the fact that many of them when injured or die they can wipe out a tank due to toxins they can expel. I just didn't want to risk it hitting a pump or powerhead and trashing a tank. you may want to do some research on your own and make the decision on what to do with it. If you can keep it contained to your fuge its a cool critter.
