It's my first time breeding so take it easy on me! I've never heard/come across a topic like this before so I thought I would ask

I've paired my spider to my pastel twice so far and I noticed lots of tail wagging and scent gland expression.

What ends up happening is (I think the girl) is excreting small urate deposits all over the tubs along with some liquid. By the morning, the whole tub is completely soaked. Just need some clarification as to if this is normal behaviour and maybe why they do it?

Thanks!!
