Dwarf Seahorse, Hippocampus zosterae, are a common shallow water species of Seahorses found throughout coastal Florida and the Caribbean. They prefer sheltered bay waters or estuaries and are rarely found in open exposed areas. In an aquarium, they do quite well but require live food, so they are probably a more difficult critter to keep than most fish or invertebrates. The picture is very beautiful specimen but we don’t want to mislead anybody that all of the dwarf Seahorses are going to look like this. We can not take any color request but we will send you a nice variety. The most common live food used in captivity is newly hatched brine shrimp, but they will also eat copepods and other small “pods”. We recommend to keep 4 or more in tank. They are between 0.5 and 1.5 inches . Our Dwarf Seahorses that we sell are wild caught.
They should be kept in a smaller aquarium, with no other fish or shrimp present, and no anemones, corals, or mushrooms. Small hermit crabs, snails, sponges, and other nano critters can be mixed with them, but they are very weak swimmers and even things like starfish can catch and eat them, so are on the side of caution. Avoid power filters and strong aeration (use sponge filters). Corals and some organism on live rock can burn them. They really like hitching posts like gorgonians, sponges and stringy algae (Cheato, Caulerpa, etc). Dwarf seahorses will breed regularly in captivity and the babies are fairly easy to raise on baby brine shrimp.
