Nope, it's a arminid nudibranch. They feed on soft corals. Check your polyps for more.

Yes, arminid, almost kinda more like Dermatobranchus but like I said that I am not sure.
Go to seaslugforum.com to have a closer look at them. Look at these and see they match
Dermatobranchus semistriatus
or all
Dermatobranchus
