Hippocampus elongatus, commonly known as the large temperate water seahorse, is a captivating addition to any specialised marine aquarium. Native to temperate coastal waters, this species is prized for its elongated body and delicate movements.
Care Level: Moderate to advanced. Seahorses require stable water parameters and specific dietary needs.
Temperament: Generally peaceful and slow-moving, Hippocampus elongatus is best kept with non-aggressive tank mates to avoid stress and competition.
Diet: Carnivorous, feeding primarily on live or frozen small crustaceans such as mysis shrimp. Regular feeding multiple times daily is recommended due to their high metabolism.
Minimum Tank Size: A minimum of 75 litres (approximately 20 gallons) is advised to provide adequate swimming space and stable water conditions.
Water Parameters: Maintain temperate conditions with temperatures between 18-22°C, salinity of 1.020-1.025 SG, and stable pH around 8.1-8.4.
Lighting & Flow: Moderate lighting is sufficient. Water flow should be gentle to moderate, mimicking natural coastal currents without causing stress.
Placement: Provide plenty of hitching posts such as macroalgae, artificial seagrass, or coral branches to allow the seahorse to anchor itself comfortably.
Compatibility: Avoid aggressive or fast-moving fish species. Ideal tank mates include small, peaceful fish and invertebrates that do not outcompete for food.
Origin: Temperate coastal waters (specific origin not provided).
Maximum Size: Up to 15 cm in length.
With attentive care and a suitable environment, Hippocampus elongatus can thrive and become a fascinating focal point in your marine aquarium.
