What is this on my Spiny Astrea Snail

[Madmandan90]

I've had my Spiny Astrea Snails for around 6 months and noticed this worm looking thing since I've had it. However, it was only when zooming in with my camera that I noticed it was actually 2 antenna of another creature. Any idea what it is? Looks cool!

Looks like a type of amphipod antenna

Nice clean zoom in!
