Kapo they can die from eating gravel can't they? what are the first symptoms of her becoming ill,she ate 2 pcs but i saw her spit one back out, the other she swallowed, do they pass them out or do they get stuck in their bodies?. I am of to bunnings now to get the sand , i have my two axies in a large plastic container with their own tank water in it, how long before i can put them back in their tank?. Will they be ok in this container for 24 hours? Thank you!
