General information

The Pacific Seahorse, scientifically known as Hippocampus ingens, is one of the larger seahorse species and is quite popular in the marine aquarium trade. This species is known for its impressive size and can be identified by its long snout and distinct coronet on the head. They exhibit a range of colors, often matching their surroundings to camouflage themselves from predators.

Care

Pacific Seahorses require a specialized aquarium setup with calm water conditions and plenty of hitching posts, such as seagrass or artificial decorations, where they can anchor themselves with their prehensile tails. They are not strong swimmers, so strong currents should be avoided. Seahorses feed on live or frozen mysis shrimp, and it's essential to ensure they are eating well in captivity.

Reproduction

Seahorses are notable for their unique reproductive behavior where the males carry the fertilized eggs in a brood pouch until they hatch. The Pacific Seahorse's breeding in captivity can be challenging, but with the right conditions, they can successfully reproduce. The male gives birth to fully formed, miniature seahorses after a gestation period.

Habitat

Pacific Seahorses are found in the Eastern Pacific, from California to Peru, including the Galapagos Islands. They inhabit shallow coastal waters, often associating with gorgonians, mangroves, and seagrasses, where they can blend in and hunt for small crustaceans.
