I have 2 crested geckos and I have had them in a 20 gall fish tank with the reptile carpet. Recently I got them a much larger reptile tank that has the fake back and the front that opens and so the crickets can't climb out out the back I got the coconut substrate. They really pounce on the crickets and I am afraid they are going to digest the stuff. Am I worried over nothing or is there something better? The Geckos are about 6 inches long and the local pet shop recommended it but watching them in action is making me wonder?
