I had one about 2 years. He actually was under the sand so I thought for about 3 months. I finally saw the tank just before lights on one day and saw the ornate leopard I had was trying to kill him. Got the ornate out and he was quickly back to normal. But he died somewhere about 2 year mark. Never found a body he just went missing. Favorite leopard for sure. Only have one male bipartitus now.
