Killifish – Austrolebias Nigripinnis Molino 2-3cm – MALE

Austrolebias Nigripinnis Molino Male – Short-Lived South American Gem That Hooks Killifish Fans Instantly

Austrolebias Nigripinnis Molino Male attracts attention with its deep black fins and distinctive patterning that develops quickly in temporary pool conditions. Hobbyists select this annual killifish to follow an entire life cycle that races from hatch to breeding in weeks. Males show bolder markings than females, which helps identify pairs easily. Their adaptation to seasonal drying creates a compelling reason for dedicated keepers to maintain breeding lines. This guide outlines key care points so you achieve healthy results.

Size and Lifespan

Males typically grow to 6–7 cm, while females reach slightly less. Lifespan usually spans 9–14 months in aquariums, though optimal setups sometimes extend it closer to 18 months. Breeders therefore plan successive generations to continue the line without gaps.

Ideal Tank Setup

Choose soft, acidic water with low mineral content and maintain steady temperatures around 26–28 °C. Install gentle filtration plus a dark bottom layer that accepts peat or coir. To replicate its natural habitat, position a weighted spawning container filled with prepared peat moss and cover the aquarium tightly to prevent jumping.

Compatible Tank Mates

Avoid housing with nippy or much larger fish since territorial behaviour appears during breeding periods. Stress rises quickly in overcrowded or mismatched groups. Suitable tank mates remain limited; most keepers house Austrolebias Nigripinnis Molino males in pairs or trios within a dedicated species tank for best outcomes.

Diet and Feeding

Supply live or frozen protein sources regularly to support rapid growth and condition. Newly hatched brine shrimp suit fry immediately, while adults take chopped bloodworms, daphnia, and tubifex readily. Add small amounts of quality dry food as variety, but rely mainly on meaty options fed twice daily.

Breeding and Behaviour of Austrolebias Nigripinnis Molino Male

Males dive into substrate alongside females during spawning dives, so prepare deep peat-filled containers in advance—condition pairs with live foods beforehand to boost egg production. Remove peat after a week, squeeze gently, dry to a moist consistency, seal for 3–6 months depending on temperature, then test-hatch small portions to release fry that accept infusoria or baby brine shrimp at once.
