well i think i started a bad habbit i gave him a super worm with no Calci dust on it and now he will not eat it? what do i do offer him nothing but Cali dusted worms till he takes it?
Try lightly dusting it, instead of caking it on there. Put a small amount in a dish and shake the superworm around in it. When they are covered in it and it is falling off of them, I imagine it is not very palatable.
In general, if you have a gecko that won't eat the supplement, you can dip your finger in water, dip it in the supplement and rub it off on the gecko's mouth. It will lick it off and get supplemented.
