Nice Bells mate. But as mentioned pebbles/rocks are not a great substrate. I had 1 of my big boys ingest about 4 or 5, 5 cent coin sized rocks a few years back. And there was only a tiny amout of pebbles around his pond. He nearly had to have surgery to remove them but the vet gave me paraffin oil (it causes everything in the bowels to be expelled very quickly) to inject into his pre items. Luckily it worked a treat and he passed them all himself. Welcome to the awesome world of laceys. Be prepared for some fun times ahead. Haha
