This guy had this out yesterday before I moved him over 2 inches. It was gone almost instantly, I figured the current took it away. I'm looking again today and I see it coming from the same head. It's much finer than a normal tentacle. Almost like it's a few pieces of hair held together with some gelatinous substance.
