They eat frozen mysidacea (crustaceans) that are readily available from aquarium stores, [53] and do not experience the stress of moving out of the wild. Although captive-bred seahorses are more expensive, they take no toll on wild populations. Seahorses should be kept in an aquarium with low flow and placid tank mates.
On average, the adult seahorse will eat roughly between 30 and 50 tiny shrimp a day. Hippocampus hippocampus are known to be ambush predators whom feed on live, moving food. They will remain still until a small animal passes within reach and then grab it. [9]
The lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse, is a species of fish that belongs to the family Syngnathidae. [3] [4] H. erectus is a diurnal species with an approximate length of 15 cm (5.9 inches) and lifespan of one to four years.
Seahorses need to eat approximately 4–5 times daily. Many aquarists who have kept H. kuda cultivate their own brine shrimp and rotifers. Daphnia is eaten when other foods are unavailable. [3] Seahorses spend most of their time anchoring to coral reefs and branches with their tails because they are poor swimmers.
When mating, the female seahorse deposits up to 1,500 (average of 100 to 1,000) eggs in the male's pouch, located on the ventral abdomen at the base of the tail. Male juveniles develop pouches when they are 5–7 months old. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small.
Adult seahorses eat 30 to 50 times a day if food is available; due to their slow consumption they must feed constantly to survive. [20] Big-belly seahorses do not have a stomach or teeth, so they feed by sucking small invertebrates in through their bony tubular snouts with a flick of their head. Their snouts can expand if the prey is larger ...
Pygmy seahorses are 14–27 millimetres (0.55–1.06 in) long from the tip of the tail to the end of the snout, so that their vertical height while swimming is still smaller. [5] An adult may be as small as 13 millimetres (0.51 in) long. [6] True pygmy seahorses have distinctive morphological markers. [5]
It is expected to feed on small crustaceans, similar to other seahorses. This species is ovoviviparous , with males carrying eggs in a brood pouch before giving birth to live young. [ 1 ] Individuals reach sexual maturity at 11 centimetres (4.3 in). [ 3 ]
