The Flame Angelfish (Centropyge loricula) is a striking addition to any marine aquarium. With its vivid orange-red body, electric blue edging on the fins, and bold vertical black stripes, it truly lives up to its name. Native to the reefs of the Pacific Ocean, particularly around the Marshall and Christmas Islands, this dwarf angelfish brings movement and colour to the mid-to-lower areas of your tank. What makes them unique, aside from their beauty, is their curious personality. They’re known for darting in and out of rockwork and can sometimes show a bit of sass towards other tank mates—especially those with similar colours or shapes. While generally considered reef-safe, they may nip at corals, so caution is advised in coral-heavy setups.
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 flame angel fish thriving, from tank setup to feeding and health tips.

Setting Up the Perfect Tank
Creating the ideal environment for a Flame Angel starts with selecting a suitable tank. Although they are small, these fish are active swimmers and need space to explore, so a tank of at least 70 litres is the absolute minimum, though 100 litres or more is preferable. They appreciate an aquascape with plenty of live rock, which provides both grazing surfaces and hiding spots. The rockwork should include caves and crevices where the fish can retreat when it feels threatened or needs to rest.
Water quality is a major factor in their wellbeing. The temperature should be kept between 24 and 26 degrees Celsius, with a stable pH between 8.1 and 8.4. Salinity should remain within a range of 1.020 to 1.025 specific gravity. Flame Angels prefer moderate flow—too little and the tank may stagnate, too much and the fish may become stressed. Using a wave maker or directional powerhead to mimic reef-like flow patterns can help. Consistency is key, and any rapid changes in water parameters can lead to stress or illness, so regular testing and maintenance are essential.
Feeding Your Flame Angel Fish
Flame Angels are omnivores and require a varied diet to stay healthy and display their best colours. In their natural environment, they graze on algae and small invertebrates throughout the day. In a home aquarium, it’s important to mimic this by providing regular meals that combine plant- and protein-based foods. A good daily routine might include marine algae and spirulina-based flakes or pellets in the morning, followed by a portion of frozen mysis or brine shrimp in the afternoon or evening. Supplementing with angelfish-specific foods that include sponge material can be beneficial for their digestion and long-term vitality.
Feeding two to three times per day in small portions tends to yield the best results. This approach not only supports their nutritional needs but also keeps them active and less prone to aggression, as hunger can make them more territorial. Uneaten food should be removed promptly to prevent water quality issues. Overfeeding should be avoided, as it can lead to obesity and excess waste in the system, both of which are harmful to marine fish health.
Health and Maintenance
In general, Flame Angel Fish are considered moderately hardy, but like many marine species, they are sensitive to stress and water quality issues. Common health problems include marine ich, flukes, and bacterial infections, which can occur if the fish is introduced too quickly to a new tank, kept in poor water conditions, or bullied by tank mates. Symptoms of illness may include the appearance of white spots, erratic swimming, flashing against rocks, clamped fins, or a sudden loss of appetite. Early detection is key to successful treatment. If you notice any of these symptoms, it’s best to move the fish to a quarantine tank where treatment can be administered without affecting the rest of the tank inhabitants. Copper-based treatments can be effective against ich but should only be used in a dedicated hospital tank, as copper is toxic to invertebrates and live rock. Regular water changes, good filtration, and a stress-free environment can go a long way in keeping Flame Angels healthy. As part of routine care, monitor water parameters weekly and look for behavioural changes, which are often the first signs that something might be wrong.
Caring for a flame angel fish is no easy task, 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 angel tales? Drop them in the comments—I’d love to hear from you!
