Lined Seahorse

Scientific Name: Hippocampus erectus
Family: Syngnathidae

About the Lined Seahorse

Species Type: Saltwater Fish
Category: Sea Horses, Pipefish, & Tasselfish

Care Level: Very Difficult. Healthy specimens are nearly impossible to find. Ships and acclimates poorly to captivity. Often refuses all foods and starves to death quickly. May have special dietary requirements that can not be met in captivity. Otherwise healthy specimens often die overnight, for no apparent reason. Not recommended for any home aquarium, best left in the ocean.
Origin: Atlantic Ocean
Compatibility/Temperament: 1


This is a common seahorse in the saltwater trade. They vary from gold to light yellow. Seahorses are not difficult to keep with the proper care and attention, but will waste away in unhealthy systems. They need to be housed in a tank of no less than 20 gallons with other passive or calm fish. They require a small but steady flow and a protein skimmer is needed to keep unwanted levels from harming seahorses. Seahorses need plenty of places to perch with their curvy tails and stay solitary. If properly cared for, seahorses readily breed in private aquaria.

Lined Seahorse Diet

Live foods only. Live brine or mysis shrimp will be accepted. Feed frequently with live foods to pray 20-30 minutes no less than 3 times a day.



Minimum Tank Suggestion

30 gallons

Ideal water parameters for Lined Seahorse

Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
