Pastel Cichlid Care Guide Summary
The Pastel Cichlid, scientifically known as Cribroheros alfari, belongs to the Cichlids - Central American family group. Adults reach a maximum size of approximately 22 cm and have a compressed body shape with a moderate growth rate. Classified as aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.
To thrive, the Pastel Cichlid requires a freshwater only aquarium with a minimum volume of 250 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 30°C, with a pH range of 6.5–8 and a general hardness of 5–20 dGH. A moderate water flow is preferred.
Due to its specialist needs, the Pastel Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Adult (Standard) 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.
Pastel Cichlid Habitat Setup
When setting up an aquarium for the Pastel 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.
Pastel Cichlid Compatibility Notes
Classified as aggressive, the Pastel Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, 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.

Fish Similar to Pastel Cichlid
Blue Sifter
Cribroheros robertsoni
A stunning Central American cichlid known for its iridescent turquoise speckling and unique earth-eating behavior. It constantly sifts substrate through its gills to forage, making soft sand absolutely mandatory to prevent gill damage. While mildly tempered compared to many Central American cichlids, it becomes highly territorial when breeding.
Macaw Cichlid
Hypsophrys nicaraguensis
A robust and stunning Central American cichlid. Uniquely among many cichlids, the females are actually more vibrantly colored than the males. They are notorious diggers and cave-spawners that will rearrange substrate. Best kept with other similarly sized, robust Central American cichlids in a large tank.
Cutteri Cichlid
Amatitlania cutteri
A stunning, robust Central American cichlid known for its striking blue eyes, vertical barring, and metallic sheen. While generally considered less aggressive than its close cousin the Convict Cichlid, it is highly territorial during breeding. They form monogamous pairs and are excellent, albeit fierce, parents that will actively dig out spawning pits.
Firemouth Cichlid
Thorichthys meeki
A popular Central American cichlid famous for the bright red coloration on its throat and belly, which it flares to intimidate rivals. They are earth-eaters, constantly sifting sand for food. While territorial, especially during breeding, they are relatively peaceful for a cichlid of their size compared to larger Central American counterparts.
Honduran Red Point
Amatitlania sp. 'Honduran Red Point'
A beautiful, smaller relative of the Convict Cichlid. They boast an iridescent blue and purple body with red or orange fins.
