How to care The Blue Striped Rivulus Killifish
The Blue Striped Rivulus Killifish (Rivulus cylindraceus) is a stunning species native to the freshwater streams and seasonal pools in South America, particularly in Brazil. Known for its striking blue stripes running along its body, it is a relatively small species, with males reaching up to 2.5 inches (6.5 cm) in length. The females are typically smaller and more subdued in color. The blue stripes are more vivid during the breeding season, and this coloration is one of the key features that make this species highly sought after by aquarists.
This species is typically found in slow-moving streams, floodplains, and pools, where they thrive in stable, slightly acidic to neutral water conditions. These habitats are often temporary, and the fish's eggs are adapted to survive desiccation, allowing them to hatch when the seasonal pools refill. This adaptation is a hallmark of many killifish species that occupy ephemeral environments.
As a carnivorous species, the Blue Striped Rivulus Killifish requires a diet rich in live foods such as brine shrimp, daphnia, and bloodworms. They will also accept high-quality pellets and flakes, though live food should be provided for their health and vibrant coloration. In terms of care, they are moderately easy to maintain in a well-maintained tank, provided that water conditions are stable. A minimum tank size of 10 gallons (38 liters) is suitable for a small group, though a larger tank would be needed for mixed-species setups or multiple pairs. They prefer a temperature range between 75-80°F (24-27°C) and a moderate water hardness of 8-15 dGH.
These fish are not particularly difficult to breed in captivity, and males will display elaborate courtship displays to attract females. However, the species has a relatively short lifespan of about 1-2 years, so breeding early in their life cycle is recommended to maximize their potential.
While not commonly found in pet stores, the Blue Striped Rivulus Killifish can be obtained through specialized breeders or online sources. Due to their stunning appearance and interesting behaviors, they make an excellent choice for experienced aquarists looking for a beautiful and rewarding species.
