The conditions for polyculture are as follows:
1, dragons must be bigger than pig-nosed turtles. Because the pig-nosed turtle will bite the red dragon's tail at some time, it will be more dangerous if the red dragon is smaller than the pig-nosed turtle.
2, the pig-nosed turtle must be fed. Pig-nosed turtles have the habit of nocturnal activities, and will chase and bite arowana when they are not full.
3. The skin of tortoiseshell should be scrubbed regularly, otherwise it will not only cause diseases such as rotten skin and nails, but also pollute the water quality and food.
Extended data:
Pig-nosed turtle is a kind of highly aquatic freshwater turtle, which lives in water all the year round except laying eggs, so its limbs are specialized into flippers like turtles. Limbs are specialized into fins to adapt to aquatic life, and cannot be shrunk into shells. There are two obvious claw nails near the midpoint of each forelimb, which is also one of its characteristics.
Living habits
Besides laying eggs, the pig-nosed turtle lives in the water all the year round, belonging to a highly aquatic reptile and omnivore, but the young turtle is a carnivore with a large appetite and aggressive nature. The tail of adult male turtle is bigger, and the position of vent hole is also relatively backward; The tail of the mother turtle is shorter and smaller.
habitat
Pig-nosed turtles are distributed in northern Australia, southern Irian Jaya and southern New Guinea, with narrow distribution and remote location. Typical habitats include rivers, estuaries, lagoons, lakes, swamps and ponds.
Predatory behavior
Pig-nosed turtles eat a lot, and their food habits are very complicated, but they are all carnivorous. Small fish and shrimps, aquatic insects, aquatic plants, and fruits and branches falling from trees are almost omnivorous.
Arowana is native to Indonesia. The main body is cylindrical. Body length is 50~ 100 cm. The body color is pink or crimson. The scales are large, reflecting a charming ruby luster, and the gill cover has a strong red color. There are a pair of short beards at the corners of the mouth. The back is smooth, and the back of dorsal fin moves above the caudal stalk, corresponding to the distance of gluteal fin. It belongs to the primitive fish on the earth and is called "living fossil".
In general, the color of arowana gradually changes from yellow to orange, then from orange to light red, and finally to deep red. The whole body glows, showing its unique charm.
Arowana likes eat small fish, shrimp, shellfish, water worms, red worms and bread worms. Easy to raise and grow rapidly.
Feed water temperature:
At 24~28℃, the water quality is neutral or slightly acidic soft water. Don't mix with small fish.
Arowana needs a lot of water for oral incubation and reproduction. Each pair of parent fish lays 40~ 150 eggs each time. The male fish will put the eggs in his mouth, which can contain 30~80 eggs at a time until the hatching is completed. When the young fish hatch, they will gather near the male fish. At night, the male fish opens his mouth and puts all the young fish in his mouth to complete this oral incubation and protect the young fish.
