These beautiful fish are best left to large public aquariums or in the ocean. They simply do not live in captivity and no one is really sure why. I hope you have not already purchased this fish before doing some research. If so, let us know about your system, tank mates and water parameters so we can help you out. If you have not purchased this fish please don't. We need to keep the demand low to discourage coollection. Best of luck...Lando
