French Angelfish are beautiful marine fish renowned for their striking colours and graceful swimming style. Native to the warm tropical waters of the Atlantic Ocean, these captivating creatures can grow quite large, often reaching up to 15 inches. Their distinctive black body adorned with bright yellow edges makes them a favourite amongst marine aquarium enthusiasts. Unlike many marine fish, French Angelfish exhibit fascinating social behaviours, often forming pairs that last their lifetime. Their impressive lifespan, typically around 15 years in captivity, means you’ll have plenty of time to appreciate their beauty. 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 French Angel fish thriving, from tank setup to feeding and health tips.

Setting Up the Perfect Tank
Creating an optimal environment is essential for the wellbeing of your French Angelfish. A spacious tank, ideally at least 125 gallons (475 litre), is recommended due to their size and activity level. Maintain the water temperature between 24°C to 28°C to replicate their natural tropical habitat together with a suggested gravity range of 1.018 to 1.021. Ensure a moderate flow rate, enough to simulate gentle ocean currents but not overwhelming for the fish. Providing plenty of hiding spaces and swim-throughs with live rock or coral structures helps replicate their natural reef environment. Consistently monitoring and maintaining water quality—keeping nitrate, ammonia, and nitrite levels minimal—is crucial in addition to keeping the pH levels between 8.1 to 8.4.

Feeding Your French Angel Fish
French Angelfish have hearty appetites and thrive on a varied diet. Include a mix of marine algae, spirulina, mysis shrimp, brine shrimp, and high-quality angelfish preparations. Providing occasional fresh seafood such as squid and clams can greatly enhance their diet. Feed your angelfish small portions twice daily, ensuring they consume everything within a few minutes to avoid waste that deteriorates water quality. Varied nutrition supports their vibrant colouration and robust health.
Health and Maintenance
While French Angelfish are generally hardy, maintaining excellent water quality is crucial to prevent common marine diseases such as marine ich and velvet disease. Regularly inspect your fish for signs of illness including white spots, cloudy eyes, or irregular swimming patterns. Quarantining new tank mates and maintaining consistent water parameters greatly reduce disease risks. If symptoms occur, promptly seek advice and appropriate medication from aquatic specialists. Routine tank maintenance, including regular water changes and filtration checks, significantly contributes to their overall health and longevity.
Caring for a French Angelfish takes some effort at times, but the payoff is immense. With the right tank setup, a tasty and varied diet, and a bit of TLC, you’ll have a gorgeous centrepiece for your aquarium. Got any questions or your own angel tales?
