Keeping Lined Seahorse in an aquarium requires the right conditions.

Aquarium Information

  • Care level: advanced
  • Temperament: peaceful
  • Diet: carnivore
  • Minimum tank size: 30 gallons (for a single pair)
  • Compatibility: Best kept in a species-specific tank or with very docile, slow-moving tank mates that will not outcompete them for food. Avoid aggressive or fast-moving fish, and invertebrates that may sting or prey on seahorses.
  • Special requirements: Requires a well-established aquarium with stable water parameters, excellent filtration, and plenty of hitching posts (e.g., artificial corals, macroalgae). A slow flow rate is crucial. Live or frozen Mysis shrimp are a staple diet, often requiring enrichment with vitamins. They are susceptible to various diseases if water quality is not maintained.
