Pineapple fish is currently a relatively common ornamental fish species, but most people don’t know what types of pineapple fish there are? Below I have shared the types of pineapple fish with you, let’s take a look! < /p>

Types of pineapple fish

According to their different colors, pineapple fish can be divided into golden pineapple fish, colorful pineapple fish, purple pineapple fish and other types.

The color of the golden pineapple fish is as light as that of a krait, and is covered with small red dots, gradually transforming into gold, which is very bright and festive.

Colorful Pineapple Fish: The back, dorsal fin, and tail fin are bright blue, and the abdomen is brownish-red.

Purple Pineapple Fish: The body color is lavender. Knowledge on raising pineapple fish

The body length of pineapple fish can reach 18-20cm. Oval shape, golden body color, red pattern on the head. The eyes are large, the mouth is small, and the irises are golden red. There is a vertical black stripe between the ends of the dorsal fin. The male fish has vertical stripes composed of small red dots on its side, arranged in a pineapple pattern; the female fish is slightly smaller than the male fish and is slightly pale white in color. Pineapple fish does not have very strict requirements on water quality. It is most suitable to grow when the water temperature is 20-25 degrees Celsius and PH7-7.2. Loves bottom activity in aquariums. They are usually quiet and gentle in temperament, but become violent and aggressive during estrus and when they are extremely hungry. Likes to eat red worms and water worms. Adult fish are best fed with blood worms or water worms. If only small fish and insects such as water fleas are fed, they will be malnourished, stunted, and become stiff fish. Therefore, once it grows to more than 4cm, it must be fed with large fish and insects.

The sexual maturity of pineapple fish broodstock is generally about 6 months, depending on its development. Generally speaking, as long as the young fish are fed normally, they can become parent fish when they are six months old.

Pineapple fish belongs to the family Liidae, so if you want to choose, it is best to start feeding them in batches when they are young. Generally, ten to twenty fish that are one to two months old are selected. When they become adults, they will automatically pair up. If you forcefully insert a pair, it will succeed, but the yield will not be very high. Pineapple fish is an oviparous fish, and the optimal water temperature for reproduction is around 26 degrees Celsius. When you see two pineapple fish licking the flower pot together, you can keep them separately. Place a long-waisted flowerpot in a 40-30 cm aquarium. The water quality is slightly acidic and appears as neutral soft water. At this time, the feeding of the broodstock should be increased. When fish lay eggs, the female first cleans the nest bed used for laying eggs, and then lays eggs. The male then follows up and ejaculates. Fertilized eggs are sticky. The egg-laying time lasts about 30 minutes, and after it is over, the parents will protect the eggs. After 24 hours, the broodstock can be removed and artificial incubation can be carried out. Because if the water quality is not right, the broodstock may eat up all the eggs. After removal, a small air pump can be used to add oxygen to the breeding tank. Let the water flow slightly to replace the parent fish. Mature broodstock will lay fewer eggs for the first time, about 100-200. After 10 to 15 days, the broodstock will lay eggs for the second time, and then every 10-15 days. However, it should be noted that after a pair of broodstock spawns three to four times in a row, the parents can be separated and raised separately for two weeks to enhance the physique of the broodstock and supplement nutrition.

When fish eggs are exposed to a water temperature of 28 degrees, the young fish can be seen shaking their tails in about 60 hours. After 3 to 4 days, the young fish begin to swim. At this time, you can feed small fish and insects, eat less and feed more. The water cannot be changed at this time. When it grows into a fish shape, you can change a small amount of new water. How to raise pineapple fish

1. Water quality: Pineapple fish has strong adaptability to water quality and is not as demanding as parrots. However, you must also pay attention to maintaining the water quality it likes to raise yellow-colored fish. . If you prefer weakly acidic soft water, never use alkaline or hard water to grow pineapples, otherwise the color of the pineapples will turn white instead of yellow.

2. Water temperature: The water temperature required by pineapple fish is not as high as that of young fish, and it can grow well from 22 to 30°C. But if you want pineapples to grow faster, it is better to keep them above 26°C.

3. Feed: Pineapple fish are not as picky about feed requirements as small pineapples. They are willing to eat artificial pellet feed, blood worms, fish eggs, shrimps, mealworms, chicken and duck livers, etc., and often eat well. Very full and can eat a lot. But the big pineapple fish loves mealworms the most and grows the fastest when eating mealworms.

4. Hair color: When the pineapple grows to 6 centimeters, you should start paying attention to the hair color. Don’t wait until the pineapple grows to more than ten centimeters before it is too late.

The color of pineapple is both reddish and yellowish. The main coloring feeds can be fish eggs (yellowing), river shrimp (reddening and brightening), and artificial coloring feeds (such as Bao Zenghong). Pineapples that have been fed with fish eggs for a long time are yellower than ordinary pineapples, and river shrimps have a strong effect on brightening the red circles under the pineapple's eyes and the red markings on its body.

5. Polyculture: Pineapples are docile large fish. Be careful not to coculture them with some overly ferocious large fish (such as Arhat and Red Devil), otherwise the fins of the pineapple will be torn repeatedly and cannot be restored. , greatly reducing the ornamental value. How to select pineapple fish

1. The yellower the pineapple fish juveniles are, the better. Do not select those juvenile fish with whitish bodies. It is best to turn off the lights and select under natural light, so that it is accurate. .

2. For young pineapple fish, you should choose pineapples with short and round bodies, not long ones. Round ones will look good when they grow up, while long ones will not.
