Care
Pot-bellied Seahorses require a specialized aquarium setup that mimics their natural environment. They need a peaceful tank with slow-moving water and plenty of hitching posts like seagrass or artificial decorations. These seahorses feed on small crustaceans, so a diet of live or frozen mysis shrimp is essential for their health. They are sensitive to water quality, so regular water changes and a stable, mature aquarium are crucial.
Reproduction
Like all seahorses, the Pot-bellied Seahorse exhibits a unique reproductive behavior where the male carries the fertilized eggs in a brood pouch until they hatch. This species can give birth to dozens or even hundreds of fry at a time. Breeding them in captivity can be challenging due to the need for pristine water conditions and the difficulty in raising the tiny offspring.
Habitat
The natural habitat of the Pot-bellied Seahorse includes seagrass beds, sponge gardens, and macroalgae in temperate waters. They are found in the coastal waters of New Zealand and southern Australia, often at depths ranging from shallow bays to about 100 meters.
