I was just looking at the Fluckers liquid calcium and it says to add 1/2 a teaspoon to every 8 oz's of water. If you think this may be to much because hes just small still cut the calcium amount in half. I imagine even if you cant get this brand the others would be roughly around same. Seems like the Fluckers one and Exo Terra have some really good reviews. I have never had to use it so i cant give a first hand opinion on which one is better. Maybe someone else that has had to use it in the past may see the thread and give there opinion. And your right all and all he looks round and healthy and he does look like hes eaten something, and if hes pooping that's clear indicator hes eaten. Its just getting the little bugger to eat them before they wipe the vitamins off. And yes some can be very stressfull to get eaten, comfortable etc where as others are good right from the get go.
