Clown Killifish

This species is extremely peaceful and easily intimidated. Tank mates must be small, calm, and non-aggressive. Boisterous or fast-swimming fish should always be avoided.

Suitable companions include small rasboras and tiny tetras. Other peaceful killifish species can work in larger setups. All tank mates should share similar water parameter needs.

Dwarf shrimp and snails are generally safe companions. The fish rarely show interest in anything below the surface. Providing space reduces accidental stress interactions.

Avoid fin-nippers and surface-dominant competitors. Community harmony depends on low stocking density. Peaceful environments allow natural schooling behavior.

Clown Killifish thrive in small, calm aquariums with gentle water movement. They prefer heavily planted tanks that provide shade and surface cover. Floating plants help them feel secure and encourage natural behavior.

Water should be clean, stable, and slightly acidic to neutral in reaction. Soft water conditions closely resemble their natural West African habitats. Regular small water changes are better than large, infrequent ones.

Lighting should be moderate, avoiding overly bright setups. Dark substrate and natural décor reduce stress and enhance coloration. Lids are essential, as this species can jump when startled.

Despite their size, stability is more important than volume. A mature, cycled aquarium prevents sudden parameter swings. Consistency in care leads to long-term health and activity.

Clown Killifish are surface-oriented micro-predators by nature. They instinctively hunt small insects and larvae at the water surface. This behavior should guide their feeding routine in captivity.

Live and frozen foods such as daphnia and mosquito larvae are ideal. These foods stimulate natural hunting responses and improve coloration. High-quality micro pellets can be accepted with gradual training.

Food should be offered in small portions once or twice daily. Uneaten food must be avoided to maintain water quality. Surface feeding rings help ensure food stays accessible.

A varied diet prevents nutritional deficiencies over time. Consistency matters more than quantity when feeding this species. Well-fed fish display stronger immunity and more vivid patterns.

Clown Killifish are relatively easy to breed in captivity. Spawning often occurs naturally in well-maintained aquariums. Dense floating plants act as preferred egg-laying sites.

Males display vivid colors to attract receptive females. Eggs are deposited individually rather than in large clusters. Adults typically ignore the eggs after spawning.

For higher survival rates, eggs can be moved to a separate tank. Incubation usually lasts around 10 to 14 days. Water quality stability is critical during development. Fry are very small and require infusoria initially. Gradually introduce larger foods as they grow. Calm conditions support steady and healthy growth.
