Care

Three-spot Seahorses require a specialized aquarium setup with calm water conditions and plenty of hitching posts, such as soft corals or macroalgae, where they can anchor themselves with their prehensile tails. They are slow feeders and prefer live foods like brine shrimp or copepods. It's crucial to ensure that they are not outcompeted for food by faster, more aggressive fish.

Reproduction

Like all seahorses, Hippocampus trimaculatus exhibits fascinating reproductive behavior. The males carry the fertilized eggs in a brood pouch until they hatch, releasing fully formed miniature seahorses into the water. Breeding them in captivity can be challenging but rewarding for experienced aquarists.

Habitat

Three-spot Seahorses are typically found in shallow coastal waters, among seagrasses and corals where they can camouflage and hunt for small crustaceans. They are native to the Indo-Pacific region, from the eastern coast of India to northern Australia and the central Pacific islands.
