Common name: White's seahorse

General information

White's Seahorse, scientifically known as Hippocampus whitei, is a captivating marine fish species belonging to the Syngnathidae family. This seahorse is named after John White, Surgeon General to the First Fleet of British ships at Sydney Cove and is endemic to the waters of Australia, particularly around Sydney. It is characterized by its unique horse-like head, prehensile tail, and the ability to change color to blend with its surroundings.

Care

White's Seahorse requires a specialized aquarium setup that mimics its natural habitat. They thrive in a tank with plenty of hitching posts, such as seagrass or artificial decorations, which they use for anchoring themselves. Seahorses are not strong swimmers; therefore, a low-flow environment is essential to prevent exhaustion. They feed on live or frozen mysis shrimp and should be fed at least twice a day.

Reproduction

Seahorses are known for their unique reproductive behavior, where the males carry the fertilized eggs in a brood pouch until they hatch. White's Seahorse males can be seen with swollen pouches during the breeding season, indicating they are carrying eggs. The gestation period lasts about 21 days, after which the male gives birth to fully formed miniature seahorses.

Habitat

White's Seahorse is typically found in shallow, inshore waters, clinging to sponges, seagrasses, or man-made structures like nets and jetties. They prefer habitats with calm waters and are often observed at depths ranging from the intertidal zone down to about 25 meters. Conservation efforts are crucial for this species as it faces threats from habitat degradation and collection for the aquarium trade.
