Lined Seahorse – Captive-Bred



The Lined Seahorse, Hippocampus erectus is a colorful and large fish that is thought by many enthusiasts to be the most attractive among seahorses. They live in a range of habitats within the Western Atlantic Ocean on the East coast of the United States. The colors of Captive-Bred seahorses vary from black shades from brown to gray. The color of their fur can change depending on the aquarium and is heavily dependent on the color of the environment. It's best in a pair or in a smaller group of its own in an aquarium that is exclusively for species that is 30 gallons or more. The higher the tank is, the better. At minimum 16 inches is ideal, since good circulation is crucial. It is able to get along with shy, small fish like gobies and firefish. But territorial, aggressive fish or swift-moving fish don't make great companions. If it is time to mate the male Lined Seahorse will be awestruck by the female through the dramatic changes in color and energetic pouch displays as well as lots of elegant dance. If it is receptive, the potential partner will tie the tails, dance, and deposit up to 600 eggs into female pouches.

They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium.
