Nudibranch Species?

[Sammydog]

Just went down to the LFS to pick up some snails and other supplies and came back with this Nudibranch.

The shop advised it was an algae eater, but I now have a sinking feeling that I have done a bad thing. Anyone able to identify it, and then tell me if I have done bad?

Looks like buying that guy was a really bad idea. :(

thanks guys, I actually found the species, and went straight back to the shop.

Swapped it for some snails and a coral.

Much happier now, and lesson learnt. Research first, not later.
