Care
Whipfin Fairy Wrasses are relatively hardy and adaptable to aquarium life, but they do require a well-established tank with plenty of live rock for hiding and foraging. They are peaceful fish that can be kept with a variety of tank mates, but they should not be housed with aggressive species that may bully or outcompete them for food. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, supplemented with high-quality marine pellets or flakes, will help maintain their health and coloration.
Reproduction
In the wild, Whipfin Fairy Wrasses are protogynous hermaphrodites, meaning they are born female and have the ability to change to male if the dominant male is removed from the group. In the aquarium, breeding is less common, but with a group consisting of one male and several females, it is possible to observe courtship displays and spawning behavior.
Habitat
Pteragogus cryptus is found in the Indo-Pacific region, particularly around coral reefs and rocky substrates. They prefer areas with moderate to strong water flow and are typically found at depths ranging from shallow waters to about 60 meters. In the aquarium, providing a similar environment with ample rockwork and good water movement will help mimic their natural habitat and support their well-being.
