Pseudomugil cyanodorsalis

Pseudomugil cyanodorsalis, known for their striking blue dorsal hue, are popular in the aquarium trade due to their vibrant color and active nature. They prefer brackish water setups that mimic their natural habitats, with plenty of hiding spots using mangrove roots or similar decorations. Dietary needs include high-quality flake food, supplemented with live or frozen options like brine shrimp and daphnia to support their active lifestyle and coloration. They are peaceful and can be kept in community tanks with other similarly-sized peaceful species. However, they may sometimes display aggression within their own species, especially males, which show off during courtship by extending their colorful fins. Breeding: This species can be bred in captivity given the right conditions. They often lay eggs on aquatic plants or spawning mops, which can be removed after spawning to prevent predation by the adults. Conservation: While not currently listed as threatened, habitat conservation is vital due to their limited distribution in the wild.
