Looking for a stunning addition to your aquarium? Look no further than Blackburn's Butterflyfish (Chaetodon blackburni) With its vibrant colors and graceful appearance, this species is a popular choice for marine enthusiasts. Growing up to 6 inches in size, Blackburn's Butterflyfish requires a minimum tank size of 100 US gallons (208 L) and a peaceful community tank setup. Feeding on crustaceans, worms, and soft coral polyps, this species may require live foods like black worms and brine shrimp to induce feeding in captivity. However, its specialized diet makes it unsuitable for reef tanks, as it may consume soft coral polyps. Captive care for Blackburn's Butterflyfish includes providing a variety of foods and well-established live rock infested with crustaceans, along with ample hiding places. Only one Blackburn's Butterflyfish should be kept per tank, unless a proven pair can be obtained, and careful attention should be given to its diet to ensure optimal health.
