Seahorses

< p style="text-indent:2em;">Seahorse is the collective name for several species of small warm-sea fish of the order Acanthosidae, family Hydrasaurus, and their body length is 5-30 cm. It is named because its head is almost at a right angle to the body. The head is horse-shaped and forms an angle with the body. The snout is long and tubular, the mouth is small, and there is one dorsal fin, which is composed of rays. The eyes can move independently.

Seahorses are not good at swimming, so they often use their tails to firmly outline the branches of corals and leaves of seaweed to fix their bodies so as not to swept away by the torrent. It is best not to keep seahorses mixed with invertebrates. They are easily stung by the stinging cells of corals and may be eaten by large anemones. When raising seahorses, the water flow should be slow and 10% of the water should be changed every week. Seahorses can conform to seawater areas without co-concentration. Their possible salinity range is 8‰-34‰, and the most suitable salinity is 25‰-26‰ (relative to density 1.015). Under normal circumstances, the water temperature for raising seahorses should be controlled at 20-26℃. If they want to grow, the temperature should be appropriately increased by 1-2℃ based on this temperature condition, with 28℃ as the upper limit, and it is best not to exceed 30℃. When the water temperature is above 30°C, seahorses will go into hunger strike, and when the water temperature reaches 32°C, they will begin to have shortness of breath and even die.



1. Little Seahorse



The body is usually brown or white, and may also appear yellow or yellow with black spots; some may also have white with small black spots. It is difficult to raise and requires a small single-species breeding tank, preferably more than four. If you are raising alone or two animals, a 20-liter tank is enough. If you are raising more than ten animals, a 50-liter tank is more suitable. Small tanks can be fed together with food. It may be mixed with conches, small resident crabs and sea dragons, but sea dragons often compete with it for food. It likes to use its tail to wrap around branch-like objects to stabilize its body. Live rocks and live sand may bring in some predators and threaten seahorses. If given more than 12 hours of light, baby seahorses may grow in the aquarium. Their growth behavior is very interesting. The male fish will shake his body, dance and change color in front of the female fish.. When the female fish gives birth, she will lay her eggs in the male's pouch. At 10 to 14 o'clock in the morning, the male fish will release the young fish. At this time, you can feed the newly hatched adult shrimp. Juveniles grow very quickly, doubling in size in 17 days, and become adults in three months. Feed newly hatched adult shrimp, copepods or other shrimp larvae.



2. Big Sea Horse





Big seahorse

Also called Golden Seahorse. Belongs to the huge seahorse. There are many colors, including yellow, orange, brown, and even black. In order to maintain the best appearance of this seahorse, the background of the aquarium should be close to the color of its body. It is difficult to raise, and individuals who grow in tanks are easier to raise. It is better to keep a single species in a 250-liter aquarium that provides branch-like objects that the seahorse can entangle with its tail. Seahorses eat relatively slowly. If they are mixed with other fish, seahorses generally will not grab food. The reaction is very slow and it is easily eaten by other fish. You can mix them with sea dragons, but sea dragons grab food faster than seahorses, so the breeders need to feed them a sufficient amount of food. Food includes a variety of shrimps and small crustaceans. Adult shrimps can also be harvested, but feeding is not recommended. You might also want to practice letting it deliver fresh bait.



3. Kiss the Seahorse





Kissing seahorses

Also called long-snouted seahorse, it mainly lives in the west of the Caribbean Sea. Might as well breed in an aquarium, body color will change with changes in the environment. They are best kept in pairs or small groups of a single species in an aquarium of 150 liters or more. The aquarium needs to be taller, at least 40 cm, and a good circulation system is very important. You may wish to mix it with some small and gentle fish, such as gobies, clowns, etc. But don't mix it with aggressive, lively fish. When in estrus, male seahorses will continuously change body color, display their abdominal pouches to attract the attention of female seahorses, and perform a very beautiful dance. If they mate with each other, they will entangle each other's tails and dance. The female seahorse will lay eggs in the male seahorse's bag, usually laying about 60 eggs. Over approximately 14 days, the male seahorse will hatch 50-400 baby seahorses. Aggressive fish will eat the food offered to the seahorses. When they first enter the tank, use live saltwater shrimp to lure them into opening their mouths. Seahorses bred in aquariums are well suited to eating frozen mysis shrimp, which is not the same as seahorses caught in the wild. It is also possible to eat amphipods and small crustaceans living on live rocks; adult shrimps rich in nutrients are also collected, but they cannot be used as main food. They eat slowly and carefully. It is best to feed frequently throughout the day. Seahorses spend most of their time attached to seaweed with their tails and have no interest in swimming. Raising seahorses is fun.
