Sea slug?

[Deadlocked]

Found this little creature making its way around. Anyone know what it is?

Thanks in advance.

Definitely looks like a nudibranch. No idea what kind. They are very specialized feeders, so unless what it eats is in your tank it will be gone.

I agree, a nudibranch, and too fuzzy and dark to identify, but might just be a Berghia Nudibranch.
