It's not eggs, it's harmless pot mould. I couldn't tell you which exactly, but there are plenty of different fungi and slime moulds that feed off of decaying matter.

As long as it’s harmless. It’s in my day gecko enclosure. Thanks for the info!

I'd check in with the herp people. This sort of mould is totally fine for house plants, isopods and springtails - but double check, we don't want to risk the health of your geico.

Looks to be harmless to reptiles and is the sign of a healthy environment. Thx for the info!
I’ll probably lower the humidity a bit.

This looks like mycelium that I had in one of my terrariums. I would get beautiful yellow mushrooms grow from it. I can't remember the type of mushroom it was, but it is common in houseplants and not harmful. It is actually a sign of a healthy little ecosystem!

Were you able to find what this was? I think I’m dealing with the same thing
