Bubble in Torch Tentacle

[king_reem23]

Has anyone ever had a bubble (or two) appear within tentacles of a torch? The torch (and the two others I have) otherwise looks happy. The bubble seems to look bigger in the evenings (which is when I took this picture; and why the tentacles look a bit more retracted than usual) and it's grown a bit (see earlier photo). It doesnt look like it's at the base, it's literally just within a single tentacle - and now happening to a second one. I haven't been able to find anyone dealing with a similar situation and would love some help. I'm still relatively new to the hobby - i'm at about 6 months maturity here.

Is the the head and around the mouth? Usually that means it’s either starting to split or in process of splitting

It’s not part of the head, it’s literally within a single tentacle
