Red Terror (Festa's Cichlid)

The Red Terror (Festa's Cichlid), scientifically known as Mesoheros festae, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 40 cm and have a compressed body shape with a moderate growth rate. Classified as highly aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a extreme level of biological waste.

To thrive, the Red Terror (Festa's Cichlid) requires a freshwater only aquarium with a minimum volume of 450 litres and a tank length of at least 150 cm. Water temperature should be maintained between 25°C and 29°C, with a pH range of 6.5–8 and a general hardness of 4–18 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Red Terror (Festa's Cichlid) is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Male, Female, and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Red Terror (Festa's Cichlid), a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Classified as highly aggressive, the Red Terror (Festa's Cichlid) is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, conspecific aggression can be intense, especially in smaller tanks, and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.
