What does seahorse mean in English?
In Japanese, it has a cool Japanese name of tatsunootoshigo (dragon spawn), but in English it is called "sea horse".
It seems that the origin of the name is different between Japanese and English. I have.
On the other hand, even in English, there is a "leafy sea dragon" that is familiar to aquariums as a closely related species of seahorses, so the appearance of seahorses seems to be associated with horses and dragons.
Unique breeding ecology of seahorses!
Seahorses have very interesting ecology not found in other fish. Males give birth to babies.In the case of ordinary fish, the reproductive ecology is such that the eggs laid by the female are fertilized by the male, but seahorses are completely different.
First, a pair of seahorses swims with their tails entwined and mates. At this time, the female lays her eggs in the male's brood pouch. Eggs are fertilized in the brood pouch and hatch in 2-3 weeks.
After hatching, the male gives birth to juveniles when the juveniles reach a size of about 5 mm. Not only the appearance but also the ecology of the fish is not so different.
Can seahorses be domesticated?
Seahorses are relatively easy to keep if you pay attention to a few things. First of all, the best bait is live mysid shrimp. Individuals farmed for pets can eat frozen food, but if you catch and raise wild seahorses, be careful as it is difficult to feed them.
Next, regarding the water flow, since seahorses are not good at swimming and their tails are tied to aquatic plants to stabilize their posture, it is better to use a weaker water flow. The water temperature varies depending on the species, but if you keep it around 22 degrees, you should be fine.
The water quality is basically the same as a normal marine aquarium, so if you are interested, why not give it a try?
