According to Guinness World Records 2009, Hippocampus zosterae (the dwarf seahorse) is the slowest moving fish, with a top speed of about 5 feet (150 cm) per hour. [21] They swim very poorly, rapidly fluttering a dorsal fin and using pectoral fins (located behind their eyes) to steer.
Fish in the order Gymnotiformes possess electric organs along the length of their bodies and swim by undulating an elongated anal fin while keeping the body still, presumably so as not to disturb the electric field that they generate. Many fish swim using combined behavior of their two pectoral fins or both their anal and dorsal fins.
The slowest-moving fish in the world is H. zosterae (the dwarf seahorse), with a top speed of about 1.5 m (5 ft) per hour. [20] Since they are poor swimmers, they are most likely to be found resting with their prehensile tail wound around a stationary object.
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy.

The seahorse fry can be kept in the same aquarium as the adults in a dwarf seahorse dedicated tank. The dwarf seahorse has a gestation period of 10–14 days and can live up to over 2 years in captivity. The water temperature in the aquarium must place between 20 and 28 °C (68 and 82 °F), with a pH ranging around 8–8.5. [12]

Ram ventilation [11] is the process in which at higher speeds, the remora uses the force of the water moving past it to create movement of fluid in the gills. At lower speeds, the remora will use a form of active ventilation, [11] in which the fish actively moves fluid through its gills. In order to use active ventilation, a fish must actively ...
