Maroon clownfish are one of the largest species of clownfish, capable of growing up to 6 inches (15cm) in length. What truly sets them apart is their deep red or maroon colouring, which is paired with either crisp white or rich gold stripes depending on the variety. These fish are particularly striking and become a real centrepiece in any tank. One notable feature is the size and dominance of the female, which is significantly larger and more assertive than the male. This species is known for being feisty and territorial, especially when protecting their space or a potential mate. Unlike many other clownfish that display peaceful community behaviour, maroon clownfish can be aggressive and are best kept alone or as part of a bonded pair. However, their confident, bold nature makes them fascinating to observe and interact with. For reef keepers looking for a fish with personality, the maroon clown is hard to beat.
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 maroon clown fish thriving, from tank setup to feeding and health tips.

Setting Up the Perfect Tank
Creating the right environment for a maroon clownfish starts with providing a suitable tank size. A single maroon clown will need a minimum of 30 gallons (114 litres), although a larger tank—such as 55 gallons or more—is recommended if you’re planning to keep a pair or include other tank mates. Water temperature should remain stable between 24 and 27 degrees Celsius (75–81°F), with a specific gravity range of 1.020 to 1.025 and a pH between 8.1 and 8.4. Maroon clownfish do well with moderate water flow. Too much flow can cause stress, while insufficient flow can lead to stagnant areas and poor oxygenation. Include plenty of live rock to create hiding spaces and natural boundaries, which help reduce aggression. If you’re experienced and your lighting setup allows, you can also introduce a host anemone such as Entacmaea quadricolor (bubble-tip anemone), though this is optional as maroon clownfish do not rely on anemones for survival in captivity. Keep in mind that their territorial nature can make them poor tank mates for delicate or passive fish, so plan the community carefully.
Feeding Your Maroon Clown Fish
A well-fed maroon clownfish is a healthy maroon clownfish. These fish benefit from a varied diet that includes high-quality marine pellets or flakes as a base, along with frozen foods such as mysis shrimp, brine shrimp, and finely chopped seafood. They also enjoy the occasional treat of live food, which provides stimulation and enrichment. Feeding should take place once or twice daily, offering only as much food as they can consume in a couple of minutes to prevent overfeeding and waste buildup in the tank. Maroon clownfish are usually enthusiastic eaters, but it’s still important to watch their intake and avoid excess. To support their immune system, you can occasionally supplement their diet with vitamin-enriched or garlic-based foods, which can help prevent common illnesses.
Health and Maintenance
Although maroon clownfish are considered hardy, they’re not immune to disease—especially in tanks with unstable parameters or poor maintenance. The most common issue you might encounter is marine ich (Cryptocaryon irritans), which appears as white spots and causes the fish to scratch against rocks or decorations. Another risk is Brooklynella, often referred to as clownfish disease, which can lead to excessive mucus, lethargy, and heavy breathing. Fin rot is also a concern, especially if your fish are in conflict with tank mates or suffer injuries. To keep your maroon clownfish healthy, it’s important to carry out regular water tests and perform weekly water changes of 10 to 20 percent. Make a habit of observing your fish daily to spot any unusual behaviour or physical changes early. Always quarantine new additions before introducing them to the main display to reduce the risk of introducing parasites or infections. If a fish does fall ill, isolating it in a hospital tank and treating it with appropriate medication—such as copper-based treatments or reef-safe alternatives—is the best course of action.
Caring for a maroon clown fish takes some effort, 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 maroon tales? Drop them in the comments—I’d love to hear from you!
