Common name: Thorny seahorse

General information

The Spiny Seahorse, scientifically known as Hippocampus histrix, is a distinctive species of seahorse characterized by its long, slender snout and the presence of sharp spines on its body. These spines serve as a form of protection against predators. The coloration of H. histrix can vary widely, often matching their surroundings to camouflage effectively. This species is a fascinating addition to the marine aquarium due to its unique appearance and behavior.

Care

Spiny Seahorses require a specialized aquarium setup that mimics their natural environment. They are poor swimmers and need structures like seagrass or artificial holdfasts to cling to with their prehensile tails. A gentle water flow is essential to prevent them from becoming exhausted. Seahorses are carnivorous and prefer live foods such as brine shrimp, mysis shrimp, and copepods. It's crucial to maintain excellent water quality, as seahorses are sensitive to changes in water parameters.

Reproduction

Seahorses have a unique reproductive strategy where the males carry the fertilized eggs in a specialized brood pouch until they hatch. The male Hippocampus histrix undergoes a pregnancy, after which he gives birth to fully formed, miniature seahorses. Breeding seahorses in captivity can be challenging but rewarding for experienced aquarists.

Habitat

The Spiny Seahorse is found in a range of habitats including seagrass beds, coral reefs, and mangroves. They are typically located in shallow waters but can be found at depths up to 70 meters. Their geographical distribution spans across the Indo-Pacific region, from the eastern coast of Africa to the waters of the Western Pacific.
