The Dwarf Seahorse (Hippocampus zosterae) can be found off the eastern coast of the United States. They hide among seagrass beds and reefs with gentle currents where they wait for small invertebrates and crustaceans. They reach a maximum size of 2 inches and should not be housed with aggressive corals, as they can harm seahorses. Seahorses should be fed 3-4 times a day and may require live food, such as brine shrimp or mysis. They are sensitive to major and sudden fluctuations in water parameters, so stability is a must when housing these animals.
