Pest or growth?

[tidefanjam]

Is this a worm growing on my bonsai? It’s growing longer, and the purple of the bonsai is growing with it, but it has small threads coming out the end of it, hard to see in the pic but they are there.

Spionid worms. I get them at the base of a lot of my acros. Seem to be harmless

Thats a vermetid snail that the coral has encrusted over. They can irritate the coral over time. If you superglue over the tip of the snail the coral will be able to smother it and continue growing normally there.

I superglued them to play it safe, whichever they are

Vermatids cast a slime net that does irritate corals
Spionid worms have little tiny antennas sticking out.

My vermetids cast slime nets and also have these antenna. Didn’t know that these spionid worms existed, learn something new everyday
