Meatball its half pebbles from my old set up and half coconut fiber. I will be covering the pebbles with coconut fiber next trip to the store. There in a 40 gallon breeder where i put in a 6in piece of plexi glass so they have like a 5 gallon pond. But i put the crickets on the fiber to feed them no worries i did my research
