Orange nudibranch on bottom of frag plug

Good or no? Came off some KP live rock from the FL keys. Pics below:

Huge guess:

​

Berthellina quadridens

Reported that these may eat sponges, anemones, and some corals (tubeastrea). I would put it in a jar with an aiptasia and if it eats that let us know!
Good luck

Good guess! Unfortunately doesn't seem like it's that species. Doesn't have the 2 tubes coming out of the front.

No aiptasia in my tank to speak of fortunately so I wouldn't be able to experiment...

Also, seems to be just going after the cyano on the plug and frag rack. Had an outbreak here recently after vacuuming too much of the sand and he popped up literally out of no where. Thought it was a sponge at first until it started moving.

If it's eating cyano. Don't chuck it.

Oh heck no, it's staying. Just wanted to know more about it if anyone had any insight.

Usually there isn't on the uncommon ones. Nice guy you got though
