The fish is spindle-shaped, slightly flat, with a fan-shaped tail fin and a straight dorsal fin. The body color is light gray-blue, and the young fish have patterns. When mature, the whole body is covered with bright blue spots, especially the head, which shines in the light, very beautiful and strong, and the body length can reach more than 20 cm. Big fish, with bulging heads and rough temperament, are not suitable for raising in the same box as small fish. I like earthworms, but I don't eat live fish and shrimp.
Feeding characteristics of 1:
Easy to maintain, low in water quality requirements, like weak acid or neutral water, the water temperature is above 20℃; Like to eat animal bait.
2 Reproductive characteristics:
It is easier to lay eggs and reproduce. Male and female are easy to distinguish. The dorsal fin and anal fin of male fish are long without tips, and the abdomen of female fish is swollen when sexually mature. The most suitable breeding temperature is about 25℃, and a thick layer of bottom sand can be laid in the tank before breeding. After the incubator, the male fish will dig sand into the nest with his mouth to lure the female fish into the nest to lay eggs. After fertilization, the parent fish will soon include the eggs in the population. The young fish hatch in 2 ~ 3 days and stay in the mouth of the parent fish. After about 7 days, it swims out of the parent fish for food, reaches maturity in 12 months, and can reproduce many times a year. The fish is oval, with a big head and a big mouth. According to body color, there are red flowers and white pictures. The main color of safflower is dark brown, with irregular orange spots and red stripes on the body surface, and circular spots with orange edges on the tail handle; The main color of the white picture is light yellow, with red patches and stripes on the body surface. Fierce temperament, can only be raised by one person. When full or in a crowded and harsh environment, it will lie lazily on its side at the bottom of the water, but it is very popular because of its fast swimming speed, quick response and flexible predation. The sexual maturity age of parent fish is 10~ 12 months old. You can usually choose a spouse. The male fish is not as fat as the female fish, with a slightly higher head, bright colored lines on the body surface, bright yellow spots on the gill cover, bright spots on the tail star, and long tips on the dorsal fin and anal fin. The female fish is slightly lighter in body color, with enlarged abdomen and wider body width. The aquaculture water temperature is 26~28 degrees, and the water quality is neutral and soft. Put a smooth marble slab (20cm x 20cm x 2cm) at the bottom of an aquarium with 80cm x 50cm x 45cm, and put the parent fish in it. The female fish approaches the ovary before giving birth, while the male fish swims around the female fish. Female fish lay 500~ 1000 eggs at a time, and the eggs are larger than ordinary fish and arranged in an irregular straight line. After 48 hours, the eggs hatch into brown larvae, after 7 days, the larvae swim and start feeding after one week. Parent fish have the habit of swallowing eggs. After laying eggs, the ovaries should be taken out and put into an incubator for artificial aeration incubation.

African cichlid, the young fish is bright yellow, and two black stripes extend from the snout to the caudal fin on the upper part of the body.
There is also a black stripe on the dorsal fin. Adult females still keep this color, while males turn dark blue, and there is a light blue stripe with metallic light from the rear edge of gill cover to the side of tail stalk end.
This fish has a strong sense of territory. Young fish can be mixed, and males often fight, so mixed culture requires larger aquariums and more hidden places such as water plants and rocks to hide vulnerable fish. Adult fish should be raised separately.
This kind of fish is artificially hatched. So reproduction is simple. The sexual maturity age of the parent fish is 6 months, and the male fish has a mating color, the body color changes to gray-black, the dorsal fin is yellow, and the side is black with light blue; The female fish has a swollen abdomen and a slightly lighter body color. The aquaculture water temperature is 27~29, and the water quality is weakly alkaline or neutral. You can choose a 50X30X35 cm fish tank to put the parent fish. After the female fish lays eggs, she puts the fertilized eggs in her mouth, and then she is attracted by the fake eggs on the anal fin of the male fish, and her mouth is close to the anal fin of the male fish, thus fertilizing the eggs in her mouth. The eggs hatch for about three days. During the incubation period, the female fish can't eat, so she constantly encourages her gills to increase the oxygen in her mouth. When the young fish swim, if there is danger, the female fish will immediately free the young fish from their mouths. 1~2 weeks later, when the larvae grow up, the females can be fished out. Female fish lay 30~60 eggs at a time.

Large South American cichlids, adult fish length: 30 cm. It is also a very popular variety. It is a popular edible fish in the country of origin. He is huge, and his stripes are more like leopards than tigers. So it is also called leopard stone fish. Huahu has a strong sense of territory, and they usually don't like other fish to disturb their cleaning work. Plus their huge bodies. So it's best not to mix the same kind of fish. After all, they are strong killer fish. Feeding water quality: no special requirements. As long as it is water, it can survive. Gender discrimination: not easy. It can only be barely distinguished by comparing the length differences of the dorsal muscles of the gluteal fins. Their reproduction is somewhat similar to that of map fish. Open propagation on smooth stones. Need more breeding waters. Therefore, it is difficult to breed successfully under the general family aquarium culture conditions. Feeding habits: carnivorous, fishy; Active water layer: common in the middle and lower layers, and can also be found in the upper waters; Temperament: rough; Have a territorial concept.
Note: Huahu likes to bite other fish, so the fish mixed with him is obviously bigger than him. Also known as longevity head and lucky fish. Lycopodiaceae South America, Costa Rica and Nicaragua.

The upper body is cyan, and the lower body is lux from chin to abdomen. Adult fish are more colorful and dazzling. Strong posture, charming dorsal fin luster, is a fierce fish, generally raised in bare tanks. Animal-loving bait can survive in any water quality, and the water temperature is above 20 degrees, so rocks are an ideal place to live. Archerfish, scientific name: Taxotes Jacob, English name: Archerfish.
Adult fish is 25 cm long, and its origin: alkaline rivers are distributed in the coastal areas from East Africa to Australia.
Meat-eating, big bait-eating, water-loving insects, gentle.
Hard alkaline water with pH 7-8 and DH 10- 12 can be cultivated. Besides, this kind of fish usually lives in estuaries. So in fact, archerfish is a kind of brackish water fish. The aquarium needs salt.
Fishing is a very interesting thing. As we all know, this guy will spray a stream of water from his tubular jaw, knocking insects on dead branches and grass leaves into the water and eating them. This special habit is unique in the aquarium world. In fact, this fish will jump out of the water and swallow the worm directly into its stomach. So pay attention to stamp when feeding.
The water column ejected by the water jet fish can reach the range of 1 m, and it almost hits the target. When it jumps out of the water, it can jump to a height of 30 cm. Therefore, attention should be paid to avoid losses when feeding shooting fish. It can be seen from their huge mouths that they need big food. Although they don't choose bait, it must be palatable.
It is difficult to identify the male and female of water-shooting fish, and it is also difficult to breed in artificial breeding environment. Now we know that their eggs are floating eggs, and archery fish will eat their own eggs. Scientific name: Cichlasoma festivum,
English name: Festive Cichlid
The length of adult fish is 15 cm, and its origin is from Amazon basin to the area with dense aquatic plants in western Guyana.
Can adapt to a variety of water quality, but if you want to raise it well, it is best to give it weak acidic soft water with PH6.5 and DH5. And because this fish is produced in natural waters with dense aquatic plants, when it is raised. You also need to plant aquatic plants intensively. Planting aquatic plants requires strong and lush, such as: water orchid, twisted leaf orchid, pepper grass, crown grass and so on. This kind of fish is similar to pineapple fish in appearance. A black line on the eye is the reason why it is named thrush. The artificial eye on the tail stalk is their defense strategy. Because it is a cichlid species in the Amazon River. It has all the habits and characteristics of cichlids in the Amazon of South America. Thrush has a strong territorial concept, but unlike other cichlids, they have a good relationship with aquatic plants. So it is generally not destroyed. They are timid fish. Extreme fear. It is not convenient to identify the sex of this fish. The identification method is basically the same as that of fairy fish and colorful fish, and it is identified from the length of fins and the shape of excretory holes of paired fish. Generally speaking, male fish have longer fins and longer excretory pore ratio. Female fish have shorter flippers. The drain hole is round and blunt. Tao Tao did not find the corresponding information about its specific reproductive process. It is said that they are cichlids that breed openly on smooth stones.
