The Lipstick Barb, scientifically known as Pethia erythromycter, is a colorful and charming species of freshwater fish native to the streams and rivers of Sri Lanka. This relatively new species to the aquarium trade is gaining popularity due to its striking appearance and sociable nature.

The Lipstick Barb is characterized by its vivid coloration. Males are particularly striking with a bright red color around their lips, which gives the species its common name "Lipstick." The body is typically golden to orange with a darker, sometimes almost black, longitudinal stripe running from the head to the tail. Females and juveniles tend to be less colorful but still maintain a subtle beauty with lighter shades of the body colors.

In terms of aquarium care, Lipstick Barbs thrive in well-planted tanks that provide plenty of hiding spaces and room for swimming. They are active and social fish that do best in groups; keeping them in schools of at least five to six individuals helps to promote natural behaviors and reduces stress. The presence of robust, fast-growing plants not only adds aesthetic value but also helps to replicate their natural habitat, providing shade and additional oxygen to the water.

The water conditions for Lipstick Barbs should be kept clean and stable. They prefer slightly acidic to neutral pH and moderate water hardness. Regular maintenance, including water changes and monitoring of water quality, is crucial to keep these fish healthy. They are adaptable to a range of temperatures typical of tropical freshwater fish.

Lipstick Barbs are omnivorous and require a varied diet to stay healthy. A good base of high-quality flake or pellet food supplemented with fresh vegetables and occasional live or frozen foods like daphnia, brine shrimp, and bloodworms will ensure they receive all the necessary nutrients. This varied diet also helps in enhancing their coloration.

Breeding Lipstick Barbs can be a rewarding experience. They are egg scatterers, spawning among the substrate or plants. To encourage breeding, the water should be soft and clean, and the fish should be conditioned with high-quality live foods. After spawning, it is advisable to remove the adults from the breeding tank to prevent them from eating the eggs.

Conservation considerations are important as the natural habitats of Lipstick Barbs can be threatened by environmental changes and pollution. Sustainable practices in the aquarium trade are essential to ensure the survival of this delightful species in both wild and captive environments.

Overall, the Lipstick Barb is an excellent choice for aquarists looking for a vibrant, active fish that can add a splash of color and life to a community aquarium. Their relatively easy care and sociable nature make them suitable for both novice and experienced fish keepers.
