Imagine a fish that looks like it’s wearing a fancy dress, complete with vertical stripes and flowing fins. That’s the Flag Cichlid for you! Its Latin name, Mesonauta festivus, perfectly captures its festive look. “Mesonauta” means “middle sailor,” possibly referring to how it gracefully swims in the middle of the water column, while “festivus” means “festive” or “joyful”.
In the fish market, you might hear this beauty called by other names like Festivum Cichlid, Barred Cichlid, or Festive Cichlid. No matter what you call it, this fish is sure to bring a splash of color and personality to any tank.
In the wild, Flag Cichlids make their home in the slow-moving waters of South American rivers, including the Amazon and Paraná basins. They love to hang out near plants, using them for shelter and as hunting grounds. These omnivorous swimmers aren’t picky eaters, happily munching on small insects, crustaceans, and even some plant matter.
One of the most endearing traits of the Flag Cichlid is its relatively peaceful temperament. Unlike some of its more aggressive cichlid cousins, this fish can often get along well with other peaceful community fish. However, they can get a bit territorial during breeding time, so it’s best to give them plenty of space.
Speaking of breeding, Flag Cichlids have a fascinating reproductive behavior. They form monogamous pairs and work together to care for their young. The parents will clean a flat surface, often a leaf or stone, where the female lays her eggs. Both mom and dad then take turns fanning the eggs and protecting their babies from hungry tank mates.
Here’s a fun fact: Flag Cichlids are excellent parents, but they can be easily spooked. If startled, they might accidentally eat their own eggs or fry! That’s why it’s important to provide them with a calm, stress-free environment during breeding time.
The history of the Flag Cichlid in the aquarium trade is a testament to its enduring popularity. First described by Austrian zoologist Johann Jakob Heckel in 1840, these fish have been captivating aquarists for nearly two centuries.

Can Flag Cichlids change color?
Yes, Flag Cichlids can change their color intensity based on mood, stress levels, and breeding condition. They may become more vibrant during courtship or paler when stressed.
Do Flag Cichlids need a heater in their tank?
A heater is recommended for Flag Cichlids as they prefer stable, warm water temperatures between 75°F and 82°F. Fluctuations in temperature can stress the fish and make them more susceptible to diseases.
How can I tell if my Flag Cichlid is male or female?
Distinguishing between male and female Flag Cichlids can be challenging. Generally, males are larger and have more elongated dorsal and anal fins. During breeding season, females may develop a rounder belly.
Are Flag Cichlids fin nippers?
Flag Cichlids are generally not known for fin nipping. However, they may occasionally nip at long-finned fish if kept in overcrowded conditions or if they feel threatened.
How many Flag Cichlids should be kept together?
Flag Cichlids can be kept in pairs or small groups. For a community tank, a pair or trio (1 male, 2 females) works well. In larger tanks, you can keep multiple pairs, but ensure there’s enough space to prevent territorial disputes.
Can Flag Cichlids live in a planted aquarium?
Yes, Flag Cichlids do well in planted aquariums. They appreciate the cover and natural environment that plants provide. However, they may occasionally nibble on soft-leaved plants, so choose hardy plant species.
