Black/gold Nudibranch

[theatrus]

Ok, no picture since he decided to hide by the time I fished out the camera.

About 3/4" long, black with gold stripes, with a white rim around him. One protrusion near the back. Couldn't find any IDs. DIdn't buy him, so he either came on the LR and I just noticed him, or somehow was attached to the new anemone (Sebae, false percs. took right to it ).

Any ideas?

There are many nudibranchs that fit very close to that description. Many are varied in their color patterns as well. Get a photo when you can. For the most part, nudibranchs are notorious coral eaters, so watch it and watch any coral you have. Granted there are many nudibranchs that don't eat coral and just eat algae. However, the majority of them seem to be not reef tank friendly. Beautiful yeah, but can degrade coral livestock.
