Hi,
i'm using a mix of soil and sand, which is quite light. It is however a bit compact, which might make digging hard.
The substrate is about 5 cm deep (2 inches), so there is a possibility that i have missed the eggs.
Hopefully I've just missed them, a fertility problem would really suck...
I'm moving them to a new cage within the next couple of days, so that i can clean sweep the old one... guess i should re-think what substrate I'm going to use.
