Just spotted this guy on the glass this morning. I have not seen him before and I'm guessing he came in on the Tonga Bullseye mushrooms I added yesterday.

It looks kindof like a little yellow cucumber. Maybe not the species seen in stores, but id say thats a cucumber of some sort.

That does look like a very small Colochirus robustus, the yellow sea cucumber.
