Help. Me and my husband are new to reefing, we started in January this year.

We have found this little guy in our tank a few weeks ago and have asked our local very knowledgeable reef shop what it is but it has stumped them. Any help would be great

It looks like a Nudibranch. The appendages on the front make me think it's a filter feeding variety but the color looks more algae to me...
