What kind of fish is this? What's its name?

Alias: piggy fish, tail star fish

Map fish is produced in Amazon River and Guyana in South America, with a body length of 350mm and an optimum temperature of 25℃, which is fierce and easy to raise. Map fish is not strict with water quality, and can live normally in weakly acidic, neutral and slightly alkaline water. Dissolved oxygen in water is relatively high. It is a fierce carnivorous fish and can't be mixed with small fish. Map fish 1 year old, about 1 cm long, sexually mature, spawning 1 10,000 boxes, breeding water temperature 28℃, fertilized eggs hatch into larvae in 2-3 days. Male fish is not as fat as female fish, with slightly higher head, bright body color, bright spots and long fins. The female fish is light in color, large in abdomen and wide in body.

Breeding: the water environment is as wide as possible, the water temperature is about 30 degrees, and it is neutral and soft. Put a smooth stone or slate at the bottom of the jar. This kind of fish lays a lot of eggs, but the hatching rate is not high. After 48 hours, take out the parent fish immediately. Maps are "poisonous" and your children will eat them! In a week, the small fish will start to feed. Just try it. I believe you will succeed!

Map fish is very interesting, psychic. After you have kept it for several years, it will swim to your side every time it is fed, shaking its head and tail to show intimacy.
