Man this sucks.
Noticed a bit of mold in one of the C elegans pill vials. Pinched it out with the small forceps and noticed it was attached to something. Inspected it under magnification and noticed a tiny exuviae.
Searched through the substrate three times one granule at a time and couldn't find the <0.5cm spider. Searched again and still couldn't find it.
I have never noticed mold growing on molts, and escape is highly improbable, so I am assuming the spider died during a molt.
The other similar sized Cyrocosmus sp I have under exactly the same conditions are doing well so I don't know how I could have prevented this.
Rip little buddy.
Dammit.
I'm not impossible. I'm being improbable.
