Tank Bred and Raised
Hippocampus erectus, commonly known as the Lined Seahorse, is one of the most iconic and captivating species of the Western Atlantic. Recognized by its elegant, upright posture and distinct network of fine, dark lines tracing its body, this species displays a remarkable range of coloration — from golden yellow and chestnut brown to deep black and even reddish hues depending on mood and environment. Graceful and deliberate in movement, the Lined Seahorse embodies the tranquil beauty of seagrass meadows and coastal reefs where it naturally occurs.
