I have 4 dumpy tree frogs in an Exo terra 18 x 18 x 24 terrarium I feed them 30 crickets a week by dumping them in their cage and letting them roam. Yes I feed the crickets a day before I feed them to my frog. i usually put flukers orange cube stuff in for the crickets to eat. Or I will put carrots and blueberries or what ever I can find in their feeder tank. I dust them and throw them in the frog tank. My problem is the calcium keeps coming off their bodies after awhile. They also like hiding in my frog tree log so it takes my frogs awhile to see them . By the time

they see them. The crickets have either lost the calcium dust or are all mostly hiding away. I throw cricket food in the frog tank also so they don't chew my 3d background up and kill my frogs due to frogs eating digested styrofoam. Is there a better way to give my frogs calcium? If I only had one or two frogs i would hand feed them and it wouldn't be a problem but that sadly isn't an option because there are so many of them.
