The Red Terror Cichlid (Mesoheros festae) is a strikingly beautiful and highly sought-after freshwater fish known for its vibrant red and orange coloration, bold black markings, and commanding presence in the aquarium. Native to the rivers and lakes of Ecuador and northern Peru, this species thrives in warm, slow-moving waters with plenty of hiding spots among submerged roots and rocks.
‎
A Name That Matches Its Attitude
The Red Terror Cichlid earns its name due to its highly territorial and aggressive nature. This is not a fish for the faint of heart—it demands respect and is best suited for experienced aquarists who can accommodate its needs. While juveniles may seem relatively peaceful, they become far more aggressive as they mature, especially during breeding.
‎
Impressive Growth and Tank Requirements
Red Terror Cichlids can grow quite large, with males reaching up to 18 inches and females slightly smaller at around 12 inches. Due to their size and temperament, they require a minimum tank size of 125 gallons, with larger tanks (150+ gallons) recommended for a pair or community setup with other robust tankmates. A well-decorated aquarium with plenty of caves, driftwood, and rock formations helps create territories and minimize aggression.
‎
Care and Water Parameters
These cichlids thrive in temperatures between 76-82°F with a pH range of 6.5-7.5 and moderate to hard water conditions. Regular water changes and powerful filtration are essential to maintain water quality, as they are messy eaters and produce a significant bioload.
‎
Diet and Feeding
The Red Terror is a carnivorous predator with a hearty appetite. In the wild, they primarily feed on small fish, crustaceans, and insects. In captivity, they should be offered a varied diet consisting of high-quality pellets, frozen foods such as shrimp and krill, and occasional live foods to keep them healthy and enhance their coloration.
‎
Unique Behaviors
One of the most fascinating aspects of Red Terror Cichlids is their intelligence and interactive behavior. They quickly recognize their owners and may even beg for food. During breeding, they display impressive parental care, with both the male and female fiercely guarding their eggs and fry.
