Dwarf seahorse and young seahorses will eat copepods, Amphipods and juvenile grass shrimp or even live brine shrimp (decapsulated), etc.

Seahorses prefer to have at least one other fellow seahorse in the tank for company. They like to swim in pairs with their tails linked to each other.


The seahorse likes to mimic things like macro algae or saltwater plants by laying still and swaying slightly in the water.


Another interesting habit displayed by the seahorse is that they can change color to match their surroundings. Seahorses will attach to sea sponges of all colors and shapes while they turn the color of the sponge. They exhibit this ability with macro algae of all colors.


Seahorses swim by fluttering a small fin like a fairy wing on their back. They can flutter this specialized fin up to 40 times per second. They also use 2 pectoral fins on the back of the head to steer.


The seahorse is able to move each eye independently so they can easily spot prey on a 360 degree. They lay still and wait to ambush prey while attached to sponges and sea weed.


A rare trait that distinguishes the seahorse from every other animal on earth is male pregnancy. In the mating process the female seahorse deposits her eggs in a special pouch on the male (her husband) and the male seahorse incubates the eggs and eventually gives birth to the young baby seahorses.


Mated seahorses engage in a complex mating ritual dance in which the pair swims while hooked to each other, change colors to show off for each other, and constantly swimming side by side with each other excluding all others. Mating can last a full day.


The Male carries the eggs and the babies in his pouch and eventually when he feels they are able to swim he releases fully formed baby seahorses.


Eggs and embryos are nurtured in the brood pouch. The male seahorse body provides all the necessary nutrients such as milk (prolactin) the hormone that mammals produce for their young. In the pouch developing seahorses are provided with energy rich lipids and calcium for their bones.


The gestation or pregnancy lasts between 2-4 weeks during which time his mate/ mommy visits him every morning to say hi before she goes out on her daily foraging.
