Berghia Nudibranch hitchhiker?

[Orion9]

Just found on the glass of my aquarium, I've not added any nudibranch but wanted to ask if anyone could confirm its a berghia?
Thanks,

I’m by no means an expert, but I’m fairly certain that there are at least several nudibranch that look very similar to berghia. In fact there are multiple species under the genus berghia.
