Red-Spotted Spot-Finned Killie (Rachovia pyropunctata) — 2,5-3cm

Overview

Red-Spotted Spot-Finned Killie (Rachovia pyropunctata) is a tiny, brilliantly patterned South American killifish that captivates specialist keepers with its intricate red spotting and fascinating seasonal breeding behavior. Associated with the Orinoco basin region of Venezuela and nearby areas, this species inhabits temporary freshwater habitats and has evolved a complex life cycle adapted to fluctuating water levels. Now available for sale UK from Tropical Fish Co, this rare and challenging killifish is ideal for the experienced aquarist seeking to explore the unique biology of annual killifish.

Appearance

The Red-Spotted Spot-Finned Killie is extremely small, typically measuring between 2.5 and 3 cm in total length. Males display a stunning pattern of red or orange spots against a pale or golden background, with delicate, transparent fins often marked with additional spotting or edging. The overall effect is jewel-like, especially under subdued lighting. Females are smaller and less vividly colored, usually showing a more uniform pale gold or olive tone. Despite their diminutive size, healthy specimens are active and alert, with clear eyes and smooth, unblemished scales.

Natural Habitat

In the wild, Rachovia pyropunctata is associated with seasonal freshwater habitats in the Orinoco basin region of northern South America. These temporary pools and flooded grasslands fill during the rainy season and gradually dry out as the dry season progresses. The fish have adapted to this cycle by laying drought-resistant eggs that can survive months of desiccation in the substrate, hatching rapidly when rains return. The water is typically soft, warm, and rich in organic matter, with minimal current and dense aquatic vegetation.

Aquarium Setup

Due to its tiny size and specialized requirements, the Red-Spotted Spot-Finned Killie is best kept in a small species-only aquarium. A tank of at least 20 litres is recommended, though larger setups are always beneficial. Use a fine, dark substrate and incorporate plenty of fine-leaved plants such as Java moss, Cabomba, or spawning mops to provide cover and spawning sites. Subdued lighting, gentle filtration, and minimal water movement will help replicate the calm, shaded pools of their natural habitat. A tightly fitting lid is essential, as killifish are excellent jumpers.

Feeding

The Red-Spotted Spot-Finned Killie is likely a carnivore, requiring a diet rich in small live and frozen foods. Offer microworms, daphnia, baby brine shrimp, and other appropriately sized meaty foods daily. Dry foods are generally not recommended for such a small and specialized species. Feed small amounts twice daily to maintain excellent water quality and avoid overfeeding. A varied, protein-rich diet is essential for maintaining health, coloration, and breeding condition.

Behaviour

This killifish is peaceful and retiring, spending much of its time among plants and cover in the lower and middle levels of the aquarium. Males may engage in mild territorial displays during spawning, but serious aggression is rare. Due to their tiny size and delicate nature, they are easily stressed by fast-moving or boisterous tankmates. A small group with more females than males is recommended to spread out any territorial behavior and encourage natural spawning.

Tank Mates

The Red-Spotted Spot-Finned Killie is best kept in a species-only setup, where its specialized care requirements and delicate nature can be fully appreciated. Due to its tiny size and peaceful temperament, it is not suitable for community aquariums. Avoid any large, aggressive, or fast-moving fish, as well as fin-nippers and predatory species. Large invertebrates should also be excluded.

Breeding

Breeding the Red-Spotted Spot-Finned Killie is challenging and requires an understanding of annual killifish biology. This species is likely an annual or seasonal killifish, meaning that eggs are laid in soft substrate or peat and undergo a period of dormancy (diapause) before hatching. Provide soft, clean water, heavy conditioning with live foods, and a fine spawning medium such as peat moss. Eggs should be collected and stored in a moist medium for several weeks to months before being rehydrated to trigger hatching. Fry are tiny and require infusoria or liquid fry food initially, graduating to baby brine shrimp as they grow.
