Nudibranch ID

[JamieC]

Howdy all, my friend found this nudibranch in his tank. It's about 1.25 inches in length. He pulled it out and some of its appendages fell off, but it's still moving around. Any ideas if it's good or bad? It's kind of cool looking.

Any idea where it was found? The only good nudi I can readily identify is the Berghia. That is not one of those. They typically look "fluffy", for lack of a better word. Here's a video I took of berghia I purchased for comparison.



The only bad nudi I can identify is a Monti eating nudi. Their appendages look more like snowflakes and seem rigid. I do not think this is a picture of that. So, not super helpful, but can rule those two out at least.

Yeah not Berghia. Too big to be a montipora eating nudi. I've never seen a zoanthid eating nudi like that...and it's not taking on any colors. I know there are a lot of types of nudibranchs...just not sure about this guy.

What soft corals do you have? Those cerata make me think of a soft coral muncher, something like clavularia or similar.

In his tank...he mostly has mushrooms and zoas

Dump it. Only two beneficial kinds of nudi in reef tanks. Bergia and the blue/black kind that eat flat worms.
