What is this black/white striped tentacle?

[ToddBell]

I've had a green mushroom colony for about 6 months. Today I notices these black and white striped tentacles sticking out between two of them. What are they?

Never had a hitchhiker like that before. That's cool. I wonder when it's going to come out of hiding.

Kinda like roaches or mice, if you see one, there's at least hundreds hiding out. Keep an eye open when you add food to the tank, if you look closely, chances are you'll see lots more arms waving.

Should I leave it or take it out

They are typically beneficial.

I apologize if my post left you worried about them. Like lockekeyy said, they're good guys.

BWAHAHAHA! I think it was the word "roaches" that did it! :lol2: I have millions in my tank! When I do water changes they all crawl out and spawn with everything else. I say they are good guys too..:thumbsup:
