Flag Cichlid Overview

The Flag Cichlid (Mesonauta festivus) is a striking and captivating species native to the freshwater rivers of South America, including the Amazon, Rio Negro, and Orinoco Rivers. Known for their peaceful nature towards their own species, they can be aggressive towards smaller fish, making careful selection of tank mates essential. These fish typically grow to sizes of 12 to 15 cm (4.72 to 5.91 inches) and thrive in well-maintained environments.

Tank Requirements

Flag Cichlids require a spacious aquarium with stable water conditions to thrive. A minimum tank size of 200 liters (53 gallons) is recommended for a small group. Maintain water temperatures between 22-28°C (71.6-82.4°F), with a pH range of 6.5 to 7.5 and a hardness level of 18 to 30°N (321.43 - 535.71 ppm). Provide plenty of hiding spots using rocks, driftwood, and suitable plants to create a comfortable environment for these fish.

Tank Setup

To create a suitable habitat for Flag Cichlids, consider the following plants that thrive in similar water conditions:

• Anubias: A hardy plant that can grow in low light and provides cover.
• Java Fern: Another low-light plant that can be attached to rocks or driftwood.
• Amazon Sword: Provides excellent hiding spots and is easy to care for.
• Cryptocoryne: Prefers stable conditions and adds a nice touch to the substrate area.

Incorporating these plants not only enhances the tank's aesthetics but also offers natural hiding places, which can help reduce stress for the fish.

Food and Feeding

Flag Cichlids are omnivores and have a varied diet that includes small fish, insects, and mosquito larvae. Occasionally, they will also consume vegetable matter as a source of roughage. A balanced diet should consist of high-quality flakes or pellets, along with protein-rich treats such as brine shrimp and other live foods. Feeding them a mix of these options will help ensure their overall health and vitality.

Sexing

Sexing Flag Cichlids can be challenging, as the differences between males and females are subtle. Males typically have slightly longer fins and may exhibit a longer snout than females, who tend to be smaller and rounder. However, these distinguishing features are not always reliable, and sexing may require observation of behavior, especially during breeding.

Breeding

Breeding Flag Cichlids can be a rewarding experience. The female will produce between 500-1000 eggs on a smooth, flat stone that the male has cleaned and prepared. Both parents will guard their eggs and fry diligently. The eggs usually hatch within 48 hours, and after another 72 hours, the fry will become free-swimming. At this stage, they can be fed finely crushed flake foods and newly hatched brine shrimp to support their growth.

Lifespan

With proper care, Flag Cichlids can live for 5-8 years. Providing stable water conditions, a balanced diet, and regular tank maintenance will contribute to their longevity and overall health.

Short Description

The Flag Cichlid (Mesonauta festivus) is a beautiful cichlid known for its relatively peaceful nature among its species, but they can be aggressive towards smaller fish, such as tetras. To create a comfortable habitat, it is important to provide a dimly lit environment with plenty of hiding places, as these fish can be somewhat timid. With proper care, Flag Cichlids make excellent additions to community tanks designed for similar-sized and temperament-compatible species.
