Helicopter-type special-shaped fish
If the alien fish can be roughly divided, they can be divided into three major categories: alien, helicopter and elf. It includes more than 90 genera, more than 650 species that have been described, and nearly 400 new species that are continuously being discovered and have yet to be species. The heteromorphic fish is the most diverse freshwater fish species after Galacinidae, Cyprinidae, and Cyprinidae, accounting for one of the exceptions among all freshwater fish species.
1. Crown Helicopter
The genus Crown Helicopterus includes 14 known species. These Helicopterus fish species look very similar to each other. When they are young, the differences are not big, so it is difficult to distinguish, and the market The origin of some of the sales is unclear, so the types of helicopters are somewhat confused, and it almost doesn’t matter how they are distinguished. No matter which type of Crown helicopter they are, their bodies are exceptionally long and tall, with the nose and nose protruding forward to form a triangle. There is an irregular black pattern on both sides of the body from the snout to the top of the anal fin. This pattern spreads from the base of the dorsal fin to the tip of the dorsal fin. Moreover, the pectoral fins of the Crown Helicopter are very large in shape. The male's pectoral fins will eventually pull out beautiful fins when they reach adulthood, which contrast with the long fins of the tail fin.
The 14 known varieties of Crown helicopters can be divided into two groups in terms of survival behavior. Some species like to rest near the roots of fallen trees on the riverside and have a certain degree of climbing ability. The other part is a more complex species that likes to exercise on sand. Crown helicopters are omnivores, and they require both plant and animal food. Cucumbers, watermelon rinds, frozen bloodworms and other novel feeds are their favorite foods.
2. Spade Helicopter

Spade-type helicopter
Spade-type helicopter has a particularly flat shape The body shape and head shape look like a Lamborghini sports car from the side, and have a triangular shape when viewed from above, which is very distinctive. They live in rivers with fine sand at the bottom. They hide in the sand during the day and look around with only the two small eyes on their heads. At dusk, they crawl out of the sand and look for food. Among the known helicopter-type fish, the Yin-Yang helicopter, also known as the color-changing helicopter, is best known to those who are interested in special-shaped fish. They have reddish-brown spots. They are also known as Chameleon Helicopters. Mainly because the body color of the chameleon helicopter will change according to its own condition and light and shade. Sometimes it is clearly black and white, and sometimes it becomes completely black. The Yin Yang helicopter is produced in Ecuador and Peru and can reach a length of up to 18 centimeters. A few years ago, the Yin and Yang helicopter was still a dream species in the hearts of players, but in the past two years it has been able to be exported safely, mainly in two colors: reddish brown and black and white.
The maintenance method of Yin Yang helicopter is the same as that of other spade helicopters, and the bottom of the tank needs to be fully covered2-3cm of fine sand, you can see them hiding in the sand during the day with only their heads and tails showing. If you didn't examine it carefully, you would never find that it was a fish, more like a fragment of two pieces of dead wood. Their eyes are constantly changing to observe the surrounding environment, and the tentacles on their upper and lower jaws play the role of tasters. As long as there is prey, they will crawl out of the sand and eat with their tails shaking. Yin and Yang helicopters are more sensitive to changes in water quality. You need to be careful when crossing the water after buying them home. Try to use an infusion set, so that they can slowly and steadily adapt to the new environment. Quiet environment and pure water quality are the two principles that protect their health.
3. Branch Helicopter
< p style="text-indent:2em;">The dendritic helicopter belongs to the genus Acestridium and Farlowela. It is a kind of strange fish among the species of heteromorphic ginseng fish, and the genus Farolowela belongs to the genus. The branch-like helicopter branches are common, and players are no stranger to the alien fish collecting strange fish. The dendritic helicopters have evolved a long rod on the head, and the entire body looks like it has been extended widely, with a large number of branches Adults of helicopter-like species are more than ten centimeters long. At the same time, this special structure prevents them from swimming and escaping quickly, but they can hide on branches submerged in the water based on their body color and shape, making it difficult to be discovered by other species.
The dendritic helicopter type is different from the spade type helicopter type and has relatively high water quality requirements. It is best to use colorless Soft water, preferably with a pH close to neutral. The water should be pure and rich in dissolved oxygen. All fish tanks are best placed in an environment close to a stream. The bottom of the fish tank is covered with fine sand and some cunning pebbles are placed. In order to facilitate their rest, you may wish to place some split bamboo behind the fish tank according to the direction of the water flow. In this way, using a Yanglang water pump to create the effect of water flow can simulate a branch-like helicopter-like wilderness living environment.
4. Dragonfly Helicopter
Dragonfly Helicopter
The dragonfly helicopter fish is the most unique among the special-shaped fish species, and it is also the most unique among the helicopter fish. There is only one representative species. The dragonfly helicopter has a relatively rich body and is solidly developed, completely covering all bodies. . The burr-like teeth on the pectoral fins are shorter, the burrs on both sides of the face are long and concentrated, like brushes, and there are shorter burrs on the back. This burr quality distinguishes the genus Hemiloricaria from the dragonfly and hyena helicopters.
Red Dragonfly Helicopter also has no extravagant demands on water quality. Just use the method of raising common alien species. It should be noted that: do not use driftwood with holes or cracks, because they are easy to get stuck inside and cannot get out. Red Dragonfly helicopters can easily deliver all kinds of food. They are typical omnivores and can eat all kinds of artificial feed that sinks to the bottom, frozen bloodworms, and annual shrimps.Make them snacks.
