Care
Bullneck Seahorses require a specialized environment to thrive in captivity. They need a mature, stable aquarium with plenty of hitching posts such as soft corals or macroalgae. These seahorses are slow, deliberate feeders and prefer live foods like brine shrimp, copepods, and other small crustaceans. Consistent water quality with low flow rates is essential to prevent stress and maintain their health.
Reproduction
Like other seahorses, Hippocampus minotaur exhibits fascinating reproductive behavior. The males carry the fertilized eggs in a brood pouch until they hatch. The courtship display is intricate and involves synchronized swimming and color changes. Breeding them in captivity is challenging and typically only attempted by experienced hobbyists or professionals.
Habitat
The Bullneck Seahorse is native to the deep waters off the southern coast of Australia. They are typically found at depths ranging from 80 to 100 meters, where they inhabit rocky reefs and seagrass beds. Due to their deep-water habitat, they are not often encountered by divers, adding to their mystique and rarity.
