The dwarf seahorse only reaches 2 inches (51 mm) because it is not an aggressive feeder. Because of its short digestive tract, food must be available to this seahorse all day.

Despite the appearance of speed here, according to Guinness World Records, this is the slowest moving fish, with a top speed of about five feet per hour (152 cm per hour).

Unlike most marine fish, the dwarf seahorse can be readily bred in an aquarium.
