sea hare/sea slug

[Mappelbaum37]

It looks like the green (more brownish then green) hair algae is subsiding. I've been battling the hair algae for a good 4 months now. I have done every single thing on the list in order to kill off the algae. (it was also a mix of diatoms). The diatoms have completely vanished. Supplies wise, I've done my part. I was thinking of getting a sea slug or nudibranch to contribute. I heard something about CUC's or some type of slug being poisinous or venomous. It would still be safe to get right? If it dies will it release toxins? If so, is the tank going to be destroyed?

* In the near future I want to add some sea stars, serpeants, shrimp and I currently have hermits, crabs, and snails. The slug will be fine with these right?

Thanks

I had a sea slug, he didn't last very long. Later I found out that most only live for about 1 year.

Did he damage anything in the tank when he died? for the time you had him, did it help out with algae?
