slug or not?

[AkainePSP]

We just aquired a 75 gallon salt tank that has been setup for about 3 years and very well established. In it it has a yellow tang, 4 striped damsel, tomato clown and 2 percula clowns. I would say there is a bout 50lbs of live rock and what appears to possibly be sponges and polyps. There are a couple of different species of feather dusters which I am extremely intrigued by but what has really gotten my attention is this thing that I am assuming is some type of slug. Its black with small tentacles, and a white stripe. Now there is not just one but I would say at least 6 or 7 and you only see them at night or when the blue lights are on making it appear like night. They don't seem to be bothering anyone was just curious about them. I have attached a picture.

Looks like some type of flatworm/nudibranch. I have no idea on species though. Here is a site that may help you.

*warning, the site has a huge amount of species to go through.

I actually saw that forum in another post and decided to inquiry there as well. This is the info I got.
