Common name: Hedgehog seahorse

General information

The Hedgehog Seahorse, scientifically known as Hippocampus spinosissimus, is a captivating species admired for its unique appearance and behavior. This seahorse is characterized by its numerous spines and striking color variations, which can range from yellow, brown, to reddish hues, often with multiple spots or blotches. They are relatively larger than many other seahorse species, reaching up to 17 centimeters in length.

Care

Hedgehog Seahorses require a specialized aquarium setup that mimics their natural environment. They thrive in a mature, stable tank with plenty of hitching posts like soft corals or macroalgae. These seahorses are not strong swimmers, so a gentle water flow is essential. They feed on small, live foods such as copepods, mysis shrimp, and brine shrimp, and they benefit from multiple feedings per day.

Reproduction

Like all seahorses, the Hedgehog Seahorse exhibits fascinating reproductive behavior. The males carry the fertilized eggs in a brood pouch until they hatch. Courtship involves intricate dances and color changes. Breeding them in captivity can be challenging but rewarding for experienced aquarists.

Habitat

Hippocampus spinosissimus is found in the Indo-Pacific region, from the eastern coast of India to northern Australia and Japan. They inhabit shallow waters, often among seagrasses, mangroves, and coral reefs where they can camouflage and anchor themselves effectively.
