Firemouth cichlid - Thorichthys meeki

Firemouth Cichlid (Thorichthys meeki)

The Firemouth Cichlid is a stunning Central American species known for its vibrant red coloration along the underside of its body. It’s a relatively peaceful cichlid but can become territorial, especially during breeding. When confronted, it has a unique intimidation display—flaring its gills and puffing up to appear larger, which often resolves disputes without actual fighting.

These cichlids thrive in well-maintained aquariums with plenty of swimming space and hiding spots like rocks, driftwood, or caves. They typically stay near the lower levels of the tank and do well with similarly sized, semi-aggressive tankmates.

Tank & Water Requirements:

• Size: 12 - 15 cm (4.7 - 5.9 inches)
• pH Range: 6.6 - 8.5
• Water Hardness: 4 - 30° dGH
• Temperature: 24 - 28°C (75.2 - 82.4°F)

Diet & Feeding:

Firemouth Cichlids are omnivores and will eat a variety of foods. A well-balanced diet should include high-quality flakes or pellets, algae-based foods, and occasional protein-rich treats like dried krill, tubifex worms, bloodworms, or brine shrimp. Providing variety helps maintain their health and vibrant coloration.

Male vs. Female:

Both males and females display the characteristic red coloration that gives them their name. However, males tend to have brighter colors, longer and more pointed fins, and are generally larger than females.

Breeding Behavior:

Firemouth Cichlids are substrate spawners, with females laying up to 300 eggs on a flat surface. The male fertilizes the eggs, and both parents take on protective roles—fanning the eggs and guarding against threats. The eggs hatch within 2-3 days, and the fry become free-swimming after about 4 more days. Parents continue to care for their young until they are strong enough to survive on their own.

Lifespan & Origin:

• Lifespan: Up to 15 years (or longer with excellent care)
• Native to: Central America – found in Belize, Guatemala, and the Yucatán Peninsula

Why Keep a Firemouth Cichlid?

• Beautiful red coloration
• Generally peaceful for a cichlid but can hold its own in a community tank
• Engaging behavior, especially its unique defensive display
• Can be bred in captivity with dedicated care

With their striking appearance and manageable temperament, Firemouth Cichlids are a great choice for cichlid enthusiasts looking for a vibrant and active addition to their tank!
