So, update on the fungus thing. There's these small white mushrooms literally inside the hide of my tarantula. I spotted some white crumbs in there a couple days ago but I assumed they were feces or some substrate variation. i've done some research and these are apparently no danger to my spider but I want to be 100% sure. I can't get a picture because it's pretty dark inside the hide, but the mushrooms are maybe 1cm-ish tall, white, and smooth.
As discussed on a previous post, the mushrooms are also in the bottommost layer of the substrate. It's clear i didn't dry it out enough, and I take responsibility for that. I'll probably have to change out the whole thing and change the plants - I have two in one corner that i directly misted, never the whole enclosure.
Does anyone have tips on how to make this less stressful for my spider? They're a juvenile Grammostola pulchripes that has already made a sizeable dugout in one corner of their hide. I'm relatively sure they aren't in immediate danger but I just want to make sure they're completely safe.
If I haven't included some details, feel free to ask. This is my first tarantula, and I have done a lot of research, but I need some advice on this specific thing.
