Feed water temperature

Because the original habitat is semi-salty and semi-fresh water, salt should be infiltrated into the sink when raising, and the concentration is 10 liter of water, and 10 gram of salt should be added. Suitable for weak alkaline water, the optimum water temperature is 22 ~ 26℃, and it is good at jumping. In order to prevent it from jumping out of the water tank, a top cover must be added.

Feeding and breeding

When breeding, put the parent fish in an aquarium with aquatic plants and let the fertilized eggs attach to the roots of the aquatic plants. A female fish can lay about 100 eggs. The fertilized eggs hatch in about 9 days, and the larvae can be fed with Daphnia or Artemia.
