General Description
The Crowned seahorse (Hippocampus coronatus) belongs to the Syngnathidae family and is native to Japan. With a maximum size of 11.0cm, this species thrives best when kept in pairs or small groups in a dedicated tank due to their unique appearance and specific care requirements.
Aquarium Suitability
Considered suitable for special aquarium setups, Crowned seahorses have average hardiness and a peaceful temperament, making them ideal for enthusiasts with the expertise to meet their demands. It's crucial to provide structures, like kelp or macroalgae, for them to latch onto with their tails, while avoiding corals and anemones that can harm them. The aquarium should have a gentle water current as they are not strong swimmers, and aggressive tankmates should be avoided to prevent damage or competition during feeding.
Demands, Care and Hardiness
Crowned seahorses require enriched food with omega-3 and vitamins to prevent malnourishment in captivity. They feed on small crustaceans and zooplankton, with live Mysis or Artemia being particularly well-suited. Maintaining water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C is paramount for their well-being.
Reef Suitability
They are always reef-safe, making them a compatible choice for reef aquariums that meet their specific care needs and tank requirements. However, caution is advised when selecting tankmates to ensure they are not aggressive towards the seahorses.
Aquarium Setup
Setting up a tank for Crowned seahorses involves providing them with suitable structures to latch onto, maintaining a gentle water current, and avoiding aggressive tankmates. A tank size of at least 100 liters is recommended for a pair or a small group, with a filtration system capable of handling their frequent frozen food feedings.
Behaviour
Crowned seahorses exhibit peaceful behavior in aquarium settings, preferring to move slowly and spend time latching onto structures with their tails. They are not particularly sensitive to water quality but require proper maintenance to thrive.
Feeding and Diet
Their diet consists of small crustaceans like Krill, Mysis, and Artemia, as well as zooplankton such as Cyclops and pods. They may require live food initially, but captive-bred specimens are known to adapt to frozen foods like Mysis more easily.
Habitat and Distribution
In the wild, Crowned seahorses are found in the waters of Japan. Due to their endangerment in the wild, they are bred in captivity in various locations, making captive-bred specimens more accessible and easier to feed. These seahorses have a life expectancy of 2-3 years and can be bred successfully in captivity with proper care.
