Identification:

  • Family: Syngnathidae (Seahorses, Pipefishes, and Leafy Seadragons)
  • Subfamily: Hippocampinae
  • Species: Hippocampus erectus (Perry, 1810) is the accepted name for this seahorse with many other synonyms.

Common Names:

Lined Seahorse, Atlantic Seahorse.

Distribution:

Western Atlantic, ranging from Nova Scotia, Canada and northern Gulf of Mexico to Panama and Venezuela.

Maximum Size:

To about six inches.

Characteristics and Compatibility:

One of the most common species in the aquarium trade, this seahorse will do well and reproduce regularly if it is offered a proper diet on a regular basis.

As with most seahorses, the Lined Seahorse does best in a quiet tank with little competition for food. Less aggressive fish such as Mandarins make good tank mates.

Seahorses require stationary perches to wrap their prehensile tails around. Since Seahorses are not strong swimmers, they do best in a tank with a low water flow.

Diet and Feeding:

Seahorses should be fed live or (if they will take it) vitamin enriched frozen or freeze-dried mysid shrimp. Seahorses should be fed several times per day with food available for 20 to 30 minutes per feeding. Wild caught Seahorses may be slow to accept frozen or freeze-dried mysid shrimp as food to begin with and may have to be fed live foods until they are weaned onto prepared foods. Tank raised Seahorses are normally trained to accept frozen or freeze-dried mysid shrimp at an early age and will make the transition to your tank much more easily than wild caught.
