I know this topic has been brought up before but none of them sounded like the turtle was actually taking chomps out of the sand. My little guy is new to his tank since yesterday so he's still exploring. One other thing...his other tank was bare on the bottom, no substrate. At what point should I start to worry about him eating too much sand? Or can he eat too much sand? I'd like to keep the sand since he's just started to kind of dig in it (cute!). But obviously if this is a danger I will not hesitate to take the sand out.
Also, he is eating his actual food normally.
Thanks for any help/advice!
