The Chinese name of the electric mermaid should be called thin-lipped rainbow silver han fish, belonging to the rainbow silver han fish family, although the number of ornamental fish in this family is not very large, but most of them are relatively easy to raise and the body color is very bright, so we gave them a louder name, called rainbow fish, we know a lot of mermaid species are among them.

In fact, we should also see that in addition to ornamental fish such as ovoviviparous guppies and cold-water goldfish, most oviparous tropical ornamental fish that prefer weak alkaline water quality are relatively easy to raise ornamental fish.
Electric mermaid is also an omnivoreous ornamental fish, the body length is about six centimeters, the staple food should also be small fish insects, bloodworms and other foods, but they can also eat artificial feed well, for food is not picky, their personality is more docile, and more lively and active, can be mixed with other small ornamental fish, the only thing to pay attention to is that the water quality should not be too acidic.
Second, the stone mermaid
Stone mermaids are native to New Guinea, also known as Burd's rainbow fish, although they are rainbow fish in the color is not bright, but their body color is more characteristic, because their front body blue and back body orange with more beautiful, so they are also very popular with ornamental fish lovers, and their body color will change with the change of the environment, in heat there is a marriage color, their body color is also many ornamental fish can not compare.

The ancestors of these mermaids mentioned above come from the seashore, so they are more suitable for weak alkaline water quality, but they are not unable to live in weak acid water quality, which is also due to years of artificial domestication, but if the water quality is too acidic, they will be life-threatening, so they can actually be mixed with many other small ornamental fish.
