1. Water quality: pineapple fish has a strong adaptability to water quality, which is not as high as parrots' requirements, but we should also pay attention to keeping its favorite water quality in order to produce yellow-coloured fish. Like weak acid soft water, do not use alkaline or hard water to raise pineapple, otherwise the color of pineapple will be white, not yellow.

2. Water temperature: the water temperature required by pineapple fish is not as high as that of juvenile fish, and can grow well from 22 to 30 ℃. But if you want the pineapple to grow faster, it's better to keep it above 26 ℃.

3, feed: the feed requirements of pineapple fish are not as picky as small pineapple, artificial pellet feed, blood worms, fish eggs, shrimp, bread worms, chicken and duck liver are willing to eat, and often eat very full, can eat a lot. But big pineapple fish love bread worms best, and bread worms grow the fastest.

4. Hair color: when the pineapple is raised to 6 centimeters, you should begin to pay attention to the hair color. Don't wait for the pineapple to grow to more than ten centimeters before it is too late. Pineapple hair color is not only red, but also yellow, hair color feed can mainly use fish eggs (yellow), river shrimp (red and gorgeous), artificial color feed (such as Baozenghong). The pineapple that has been fed fish eggs for a long time is more yellow than the general pineapple, while the river shrimp has a strong brightening effect on the red circles under the pineapple's eyes and the red markings on the body.

5, mixed culture: pineapple is a docile large fish, be careful not to mix with some too fierce large fish (such as Luohan, red devil), otherwise the fins of the pineapple will be torn repeatedly and can not be restored, greatly reducing the ornamental value.
