I use cocobrick for the tarantula, blue tongues and waterdragon, playsand for the beardies, aspen for all the snakes except the rainbows and royals who get rainforest substrate!
Never really been a fan of astroturf.
I use newspaper for quarentine vivs, if any of my beasts get ill and when I put the blue tongues together for breeding.
I think calcisand is fine but reptisand is less dusty. I'm a big fan of savannah beech chips but aspen is cheaper so I tend to go with that as my vivs are many!
I hate astroturf.
Never really had a problem with any, though coco can be a bit sticky for frogs and the like.
Bam- Your froggy probably would find the sand to drying!
