RBTA question

[zenpytho]

so i was checking out my rbta today and noticed that one of tentacles is actually forked it splits about 1" down from tip also nitced another one is starting to fork didnt know if this is common or not also it has grown alot when i got it it was appr. 3" inches or so and now 2 months later its size of paper plate but it never has "bubbled" up

Not unusual for a BTA to have a forked tentacle.
