Also called the Long Snout Seahorse, the Hippocampus Reidi Seahorse is one of the most beautiful of all seahorse species, displaying almost unnatural shades of yellow, orange, and red.Tank Bred in Sri Lanka , their coloration may change in the aquarium and is highly dependent on the colors of its environment. They are a slender, narrow bodied slow growing sea horse that can reach in an aquarium lengths of 51/2 - 6 inches long and may live 5 to 7 years with proper care. Rated the most popular, exotic and colorful sea horse in the world by hobbyists everywhere, they are native to the waters of Brazil. They best when kept as either a mated pair, or with a small group of its own kind in a species-only aquarium of 20 gallons or larger. The taller the aquarium, the better, at least 12 inches high is best, as good circulation is most important. It will get along well with small, shy fish such as gobies, ocellaris and percula clowns, and firefish. But aggressive, territorial fish, or fast-moving fish do not make good companions. When ready to mate, the male Brazilian Reidi Seahorse will impress the female with its dramatic color changes, energetic pouch displays, and lots of graceful dancing. If receptive, the future mate will entwine tails, dance, and promenade with it, and then deposit as many as 600 eggs in the male pouch. About 14 days later, the male will give birth between 50-400 perfect miniature replicas of the pair.
