In recent years, swordfish has become one of the essential fish in aquarium. Through artificial optimization, many new species have been cultivated, such as red sword, yellow sword, black fin white sword, mandarin duck sword, white sword, black fin red sword, etc. There are also changes in the shape of the fins. For example, the upper and lower leaves of the caudal fins are lengthened like swords, and the dorsal fins and caudal fins are grown up. For example, the high fin red sword is the best in the sword.
Red arrow tail with high fin
The fish is about 10 cm long. It is the same as swordfish in shape. Its body color and fin shape have changed. Its whole body is bright red. There are also dark red ones, like a broad red carpet. The purple and red stripes in the middle of the body side are not obvious, especially the high dorsal fin. When it is still, it looks like an accordion to be pulled, folded and neat skirt pleats. When it is swimming, the Qin curtains slowly open, soft and elegant, just like a red hunting flag, fluttering in the wind. The red swordtail with high fins is as gorgeous as red velvet. You can enjoy the bright red color no matter when you watch it in bright or dark conditions or against the light. The species with red eyes are even rarer, which are rare in this kind of fish.

Sagittarius is distributed in Mexico. The original Sagittarius is 7-8cm long and grows after being raised artificially, about 10cm-12cm. Swordtail is an indispensable species in aquarium. The body of Sagittarius is like a spindle, similar to that of moonfish, but the tail handle is long, the dorsal fin is in the middle, and the ventral fin is in the abdomen. The prominent sign is that the lower leaf of the tail fin of male fish extends like a sword, and some of them are longer than the body length, hence the name.
Red arrow fish has a strong adaptability and is easy to raise. Generally raised in 24-26 degree water, it is difficult for fish to survive in weak acid, neutral or slightly alkaline water at the same time, but red arrow fish is an exception, it can grow and reproduce. On the other hand, Sagittarius has a certain cold resistance, and can endure 5 ℃ low temperature in a short period of time.
Although the red arrow fish has the name of "arrow", it is thought to be a belligerent fish by its name. In fact, on the contrary, red arrow fish are not belligerent. They are gentle and kind. They never bully the weak or different kinds of people. They can be mixed with other tropical fish. Red arrow fish like to jump, especially when they are pleasantly surprised, their jumping ability is stronger, and their jumping ability is very strong, so they usually add a cover plate on the top of the aquarium.

For example, there are more males in swordtail, which is not surprising.
