Hippocampus erectus

The Lined Seahorse is a peaceful, reef-safe species admired for its unique appearance and captivating behavior. Its elongated body features prominent vertical dark lines against a pale background, giving it the signature lined look. With a prehensile tail and upright posture, this seahorse can anchor itself to coral, seagrass, or macroalgae, adding both charm and movement to any reef aquarium. In the wild, Lined Seahorses are found in shallow coastal waters, including seagrass beds, mangroves, and coral reefs, at depths ranging from 0.5 to 30 meters. They are slow swimmers and rely on their coloration and texture to blend with their surroundings, making them intriguing, stealthy additions to a tank. In captivity, they thrive in well-established aquariums with plenty of live rock or macroalgae for shelter. They are generally peaceful and do best when kept singly or as a mated pair. Feeding requires small live or frozen foods such as mysis shrimp, copepods, and other microcrustaceans, offered frequently in small amounts to support health and coloration. Growing to about 7 inches (18 cm) in length, the Lined Seahorse is a fascinating and visually striking species that brings natural behavior and elegance to nano and reef aquariums.
