They are smaller than other species of killifish, with males reaching up to 2.5 inches (6.5 cm) in size, while females tend to be a bit smaller.
In their natural habitat, the Nematolebias whitei is typically found in shallow, slow-moving waters with rich vegetation along the riverbanks. These habitats are often characterized by warm, slightly acidic waters with plenty of hiding spots provided by submerged plants and other organic material. Nematolebias whitei has adapted to this environment by spawning its eggs in the soft substrate, where they are protected from predators.
In the aquarium, this species is relatively easy to maintain, as long as the correct environmental conditions are provided. A minimum tank size of 10 gallons (38 liters) is sufficient for a small group of Nematolebias whitei, although larger tanks may be required if multiple pairs or other species are kept. The water should be kept slightly acidic, with a pH of 6.5-7.5 and a temperature range of 75-80°F (24-27°C). The water hardness should be between 8-12 dGH, and a slight salinity of 1.005-1.015 is recommended. These fish prefer clean, well-maintained water, so filtration is essential for maintaining water quality.
As carnivores, Nematolebias whitei thrives on a diet rich in live foods such as brine shrimp, bloodworms, and daphnia. High-quality pellets and flakes can be offered as supplementary foods, but live foods should be the primary component of their diet to ensure their health and vibrant coloration. It is also important to offer the fish a balanced diet to support their breeding behaviors and overall vitality.
Breeding Nematolebias whitei in captivity is relatively straightforward. These killifish are egg-layers, and females will typically deposit their eggs in soft substrates, such as fine sand or gravel, during spawning. The eggs will hatch in around two to three weeks, and the fry grow quickly. Nematolebias whitei has a lifespan of 1-2 years, making them a short-term addition to your aquarium, but one that can bring color and life to any tank.
