Chaytor's Killie (Roloffia chaytori) — 3-4cm

Overview

Chaytor's Killie (Roloffia chaytori) is a small, elegantly patterned West African killifish that brings vivid personality and color to the specialised aquarium. Endemic to freshwater habitats in Ghana, this species is prized among killifish enthusiasts for its delicate finnage, peaceful demeanor, and fascinating natural behaviors. Now available for sale UK from Tropical Fish Co, this rare killie rewards patient keepers with unique breeding opportunities and the chance to maintain a beautifully planted, calm environment that mirrors its wild forest-stream origins.

Appearance

Chaytor's Killie typically reaches around 3.5 cm in total length, making it one of the smaller members of the killifish family. Males display vivid coloration, often showing intricate patterns of red, gold, and blue markings across their flanks and fins, while females tend to be more subdued in tone. The elongated body and delicate, flowing fins give this species an elegant silhouette, and under subdued lighting the colors can appear remarkably intense. Healthy specimens exhibit clear eyes, smooth scales, and fins free from damage or clamping.

Natural Habitat

In the wild, Roloffia chaytori inhabits shallow, slow-moving forest streams and seasonal pools in Ghana. These waters are typically soft, slightly acidic, and rich in organic matter, with dense riparian vegetation providing shade and cover. The substrate is often covered in leaf litter, and the water is stained tea-brown with tannins. During the dry season, water levels can drop significantly, and killifish populations concentrate in isolated pools, which has shaped their life history and breeding strategies.

Aquarium Setup

A small, well-planted aquarium of at least 60 litres is ideal for Chaytor's Killie. Use a fine, dark substrate and provide plenty of cover in the form of live plants such as Java moss, Java fern, Cryptocoryne species, and floating plants to diffuse lighting. Include driftwood, dried almond leaves, or similar tannin-releasing materials to replicate the tea-stained waters of their natural habitat. Ensure the tank has a tightly fitted lid, as killifish are exceptional jumpers and can easily escape through small gaps. Subdued lighting and minimal water movement will make the fish feel secure and encourage natural behaviors.

Feeding

Chaytor's Killie is a carnivore and requires a protein-rich diet to thrive. Offer small live and frozen foods such as daphnia, brine shrimp, mosquito larvae, and bloodworms daily. Supplement with quality micro-pellets or finely crushed flakes if accepted, but live and frozen foods should form the bulk of the diet. Feed twice daily in small amounts to maintain excellent water quality and prevent overfeeding. Varied nutrition will enhance coloration and support breeding condition.

Behaviour

This killifish is peaceful and relatively shy, spending much of its time exploring the lower and middle levels of the aquarium among plants and cover. Males may engage in mild territorial displays, spreading fins and showing off to one another, but serious aggression is rare. They are best observed in a quiet environment where they feel secure, and when well-settled they will venture into open areas to feed. A group of one male to two or three females is recommended to spread out any territorial behavior and encourage natural spawning.

Tank Mates

Chaytor's Killie is best kept in a species-only aquarium, where its delicate nature and specialised care requirements can be fully appreciated. If tankmates are desired, choose only very small, peaceful, non-competitive species such as small snails or microrasboras in a larger setup. Avoid any fast-moving or boisterous fish, as well as large predatory species and fin-nipping tankmates. Large predatory invertebrates should also be avoided, and shrimp may be eaten or harassed.

Breeding

Breeding Chaytor's Killie in captivity is achievable with careful preparation. Provide a spawning mop or fine-leaved plants such as Java moss where eggs can be deposited. Eggs are usually laid among vegetation or in the substrate, and it is advisable to remove them to a separate container for incubation to protect them from being eaten by adults. Fry are tiny and require infusoria or liquid fry food as a first meal, graduating to baby brine shrimp as they grow. Maintain soft, clean water and stable temperatures throughout the breeding process.
