Well - the Japanese Leopard/Banded Houndshark is one of best hound sharks and active swimming sharks to keep in my opinion. As they are smaller and much more sub-tropical (in water temps) than the California cousins.
Still the 560-gallon aquarium will make for a nice grow out tank for the Brown banded Bamboos and the Japanese Leopard, for the next 24-30 months. Then you will need to have a large saltwater pond - at least 2,500-3,000 gallons (12 feet diameter). Keep in mind Brown-banded Bamboos average about 42 inches (106 cm) long - and can max out at 52-54" (132-137 cm). While Japanese Leopard/Banded Houndshark - average about 48" (122 cm) and max out at about 60" (152 cm).
