The Majestic Angelfish, also known as the Blue Girdled Angelfish, is prized for its stunning appearance. Adults display a vibrant mix of royal blue, yellow, and black with curved lines and a bright yellow patch mid-body. Native to Indo-Pacific reefs, this fish can grow up to 10 inches (25 cm), making it a standout in larger aquariums. What makes them unique is their transition in appearance from juvenile to adult; juveniles look entirely different, usually showing dark blue with white curved lines, almost like an entirely different species. They are semi-aggressive and require a spacious, mature tank to thrive. I’ll never forget the first time I spotted one in my local aquarium shop—its vibrant colours instantly hooked me, sparking my journey into understanding its care needs. In this beginner-friendly guide, we’ll cover everything you need to know to keep your majestic angel fish thriving, from tank setup to feeding and health tips.

Setting Up the Perfect Tank
Majestic Angelfish need a well-established saltwater aquarium of at least 180 litres (around 50 gallons), though larger is better. These fish enjoy moderate to strong water flow and require plenty of live rock for grazing and hiding. Water temperature should be kept between 24°C and 27°C (75°F to 81°F). pH should be stable between 8.1 and 8.4, with salinity levels around 1.020 to 1.025. Regular maintenance, including water changes and monitoring ammonia, nitrate, and nitrite levels, is essential. Because Majestic Angelfish can be territorial, provide plenty of swimming space and visual barriers to help manage aggression.
Feeding Your Majestic Angel Fish
These angelfish are omnivores and require a varied diet to remain healthy. Offer a mix of high-quality marine flakes or pellets, along with frozen foods like mysis shrimp, brine shrimp, and finely chopped seafood. It’s also essential to supplement their diet with marine algae or seaweed sheets to support their digestive health. Feed them 2-3 times per day, but ensure you’re not overfeeding. Uneaten food can quickly degrade water quality. Over time, many Majestic Angelfish can also be trained to eat from your hand, which adds to their charm.
Health and Maintenance
Majestic Angelfish are relatively hardy but can be prone to common marine illnesses like marine ich (white spot disease) and HLLE (Head and Lateral Line Erosion). Signs of illness include loss of colour, scratching against rocks, laboured breathing, or reduced appetite. Maintaining pristine water quality is your best defence. Quarantining new fish before introducing them to the display tank is highly recommended. If illness does strike, early treatment in a hospital tank with copper-based medication or reef-safe treatments can be effective. Regular observation and quick action are key to keeping your angelfish in top health.
Caring for a Majestic Angel fish takes some effort and work, but the payoff is immense. With the right tank setup, a tasty and varied diet, and a bit of TLC, you’ll have a dazzling centrepiece for your aquarium. Got any questions or your own majestic tales?
