WTF is creeping around in the soil of my Alocasia cuprea Red Secret?
My cousin bought this alocasia for me 3 weeks ago. It was meant as a rescue because it looked so sad and damaged in the store (big plant center).
Today I wanted to water it and saw a tiny dark grey-ish worm crawling in the soil (on the right of the stem). I can also see (spider) webs in the holes in the uneven soil. WTF even is this? It's not even crawling like a worm but more like sliding up and down on a thread of the spider web.
It has lost 3 leaves since he bought it for me and now left with two. Kind of regretting trying to rescue it now.
Does anyone know what is it and how I get rid of it? Do It repot immediately? How do I protect my other plants? Will quarantining be enough?
First picture is of the soil now with the small grey worm thing (that looks like a little stick/branch of wood). Last picture is the alocasia when I first got it.
I'm a new plant mom and first time I see anything crawling in/on one of my plants so I'm freaking out.
P.S. English is not my native language so sorry if something isn't clear.
