Jubb's Nothobranch, (Nothobranchius jubbi - jubbi) - Killifish for Sale UK

Overview

The Jubb's Nothobranch (Nothobranchius jubbi) is a tiny, brilliantly patterned annual killifish native to Northeastern Africa, especially Kenya, Somalia, and Ethiopia, where it is found in temporary pools, ditches, marshes, and rain pans. Reaching 3.5cm in length, this peaceful species is prized for its fascinating breeding behavior and vivid color. As an annual killifish adapted to temporary habitats that dry seasonally, Nothobranchius jubbi has a compressed life cycle and unique reproductive biology. Available for sale UK from Tropical Fish Co, this rare species rewards experienced keepers with captivating displays and unique behaviour.

Appearance and Coloration

Jubb's Nothobranch displays stunning colouration with a compact, robust body adorned in vivid blues, reds, and yellows with intricate patterning that creates a jewel-like effect. Males are intensely coloured with pronounced finnage and a bold presence, especially during courtship. The scales shimmer with metallic iridescence under subdued lighting. Females are smaller, plumper, and more subdued in colour with shorter finnage. In a planted tank with dark substrate, the colours become even more vibrant and eye-catching.

Natural Habitat

Nothobranchius jubbi occurs in north eastern Africa in Kenya, Somalia and Ethiopia in temporary pools, ditches, marshes and rain pans, normally ones without any connections to rivers. These temporary water bodies fill with water during the wet season and dry completely during the dry season. The water is typically soft, slightly acidic to neutral, and well-vegetated, with a substrate of mud and organic debris. During the wet season, adults spawn rapidly; as pools dry, adults perish while eggs remain dormant in dried substrate, hatching when rains return months later.

Aquarium Setup

A minimum 40-litre aquarium is recommended for a pair or small group of Jubb's Nothobranch. Use a fine sand or soft peat substrate to replicate the natural spawning medium. Include live plants such as Cryptocoryne, Java moss, and floating species like Salvinia or Limnobium. Provide spawning mops or peat moss for egg deposition. Lighting should be subdued, and filtration gentle to avoid strong currents. A secure, tight-fitting lid is essential, as these small fish are strong jumpers. Maintain excellent water quality.

Feeding and Diet

As a carnivore, Nothobranchius jubbi requires a varied, protein-rich diet to maintain health and colour. Offer small live and frozen foods such as daphnia, brine shrimp, mosquito larvae, grindal worms, and other tiny invertebrates daily. High-quality prepared foods may be accepted but should not be the sole diet. Feed small portions twice daily, removing uneaten food promptly to maintain pristine water quality. Variety and freshness are critical for optimal health and vibrant colouration.

Behaviour and Temperament

Jubb's Nothobranch is a peaceful species that spends most of its time exploring the lower and middle water column. Males may display to each other during courtship with flared fins and vibrant colour displays, but serious aggression is rare. These fish have a naturally short lifespan of typically 6-12 months, reflecting their annual biology. They appreciate a dimly lit aquarium with plenty of cover. They are not competitive feeders, so avoid housing them with boisterous or fast-moving species.

Suitable Tank Mates

A species-only setup is recommended for Nothobranchius jubbi. Possibly very small, peaceful tankmates only in a larger tank may be suitable, but this is not generally recommended. Avoid large fish, aggressive fish, fast boisterous species, fin-nippers, and species that will outcompete them for food. A calm, quiet environment is essential for this delicate annual killifish to thrive.

Breeding

This annual killifish lays eggs in the substrate. Condition a pair or small group with high-quality live foods, then provide spawning media such as peat moss or fine sand. Eggs usually require a drying/incubation period before hatching. Use a spawning mop or peat/sand spawning medium and separate adults from eggs to prevent predation. Collect eggs carefully and store in slightly damp peat in a sealed container. Fry hatch when the peat is re-flooded and require infusoria or newly hatched brine shrimp. Breeding success depends on careful egg management and providing soft substrate or spawning medium with gentle filtration.
