Care

Caring for Fisher's Seahorses requires a dedicated and stable environment. They thrive in mature tanks with plenty of hitching posts like soft corals or gorgonians. Seahorses prefer a gentle current and need a diet of live or frozen mysis shrimp, enriched with vitamins to maintain their health.

Reproduction

Fisher's Seahorses are ovoviviparous, with males carrying the fertilized eggs in a brood pouch until they hatch. Breeding in captivity can be challenging but rewarding, with proper water quality and nutrition being crucial for success.

Symbiosis

While not symbiotic in the traditional sense, seahorses often form associations with sessile invertebrates like corals, which provide them with camouflage and a structure to anchor themselves.

Habitat

Native to the Central Pacific, Fisher's Seahorses are found in shallow waters, often among seagrasses and coral reefs where they can camouflage and hunt for small crustaceans. They are typically found at depths ranging from intertidal zones to about 100 feet.
