Common name: Three-spot Seahorse
General Information
The Three-spot Seahorse, scientifically known as Hippocampus trimaculatus, is a unique and captivating species within the aquarium trade. Known for its distinct appearance, this seahorse is characterized by three prominent dark spots along its body, which serve as its namesake. This species is a fascinating addition to any aquarium due to its unusual shape and gentle demeanor.
In the wild, the Three-spot Seahorse is found in shallow coastal waters, often among seagrasses and mangroves. Its importance in the hobbyist community is notable, particularly for those interested in seahorse-specific aquariums. However, due to its specific care requirements, it is more suited for experienced aquarists dedicated to meeting its needs.

Care
Caring for a Three-spot Seahorse requires a well-maintained aquarium that mimics its natural habitat. Seahorses are best kept in species-specific tanks to prevent competition for food and to ensure their unique swimming needs are met. A tank with a gentle water flow, plenty of hitching posts like artificial corals or seagrass, and a sandy substrate will provide an ideal environment.
Seahorses are sensitive to water quality, so regular monitoring and maintenance of water parameters are crucial. They thrive in tanks with stable temperatures and salinity levels, mimicking their natural environments.
Diet and Feeding
Three-spot Seahorses are carnivorous and primarily feed on small crustaceans in the wild. In captivity, they should be provided with a diet of live or frozen mysis shrimp, enriched brine shrimp, and other small crustaceans. Feeding should occur multiple times a day, as seahorses have small stomachs and require frequent meals to maintain their energy levels.
Behavior and Compatibility
Seahorses are known for their peaceful nature and can be kept with other non-aggressive species that do not compete for food. However, they are best housed with other seahorses or invertebrates like snails and shrimp that do not pose a threat. Their slow swimming and unique feeding habits make them incompatible with fast-moving or aggressive tank mates.
Reproduction
Three-spot Seahorses exhibit a fascinating reproductive behavior where males become pregnant. After a courtship dance, the female deposits eggs into the male's brood pouch, where he fertilizes and carries them until they hatch. Breeding in captivity can be challenging due to the specific conditions required for the fry's survival, including specialized feeding and rearing environments.
Health and Common Issues
Seahorses are susceptible to stress and water quality issues, which can lead to health problems like bacterial infections. Ensuring a clean, stable environment and a proper diet are key to maintaining their health. Regular observation for signs of illness, such as changes in color or behavior, is important for early intervention.
Habitat
The Three-spot Seahorse is native to the Indo-Pacific region, including the waters around India, Thailand, and the Philippines. They inhabit shallow coastal areas, often among seagrasses and coral reefs, where they can find ample food and protection. Their natural habitat is characterized by warm, tropical waters with abundant vegetation.
Conservation Status
Hippocampus trimaculatus is listed under CITES Appendix II, indicating that trade must be controlled to avoid utilization incompatible with their survival. Conservation efforts focus on habitat protection and sustainable trade practices to ensure the species' longevity in the wild. Ethical considerations for pet keeping include sourcing captive-bred individuals to reduce pressure on wild populations.
