Sorry for the late reply. I’ve managed to take a photo under white light, my blue cheek goby just brushed past them so they’re not out completely Hope this helps.
Very close to a morph commonly sold under the name Armor of Gods. Yours have a nice bright bit on the tentacles which suggest they could color up into a really nice morph like WWC's "balrog".
The names are stupid. I just call them 'orange', 'red', etc.
