It is not easy to raise red-bellied piranha. They are tropical freshwater fish and have some requirements for water quality and water temperature. Weak acid soft water has the best quality, and the water temperature cannot exceed 30 degrees Celsius.
This kind of fish is very fertile. You can breed many times a year, and the breeding cycle is very short, but you need to take care of it in time during the breeding process, otherwise you will eat eggs.
At the same time, because this kind of fish is carnivorous, it has special requirements for bait. Sharp teeth, bad temper, unfriendly to other fish, so you need to avoid raising with other fish. They are not very friendly to the same kind and ecological environment and cannot be released directly. Novices are advised not to breed as much as possible.
How to raise red-bellied piranha
1. Inlet water quality: weak acid soft water is preferred.
2. Inlet water temperature: 22 ~ 28℃.
3. Stocking form: monoculture, not mixed with other fish.
4, breeding difficulty: strong physique, easy to raise, pay attention to hurting people.
5. Aquaculture water temperature: Aquaculture water temperature is about 26℃.
6, breeding methods:
① Before breeding, the red-bellied piranha can spread a layer of Hypericum japonicum or palm silk on the bottom of the tank, and put the parent fish in the ratio of 1: 1. After chasing for a day, you can lay eggs, which is the egg palm.
② After spawning, the parent fish should be fished out in time to avoid eating eggs by mistake. Each parent fish lays 300 ~ 600 eggs at a time, the fertilized eggs can hatch after 48 hours, and the larvae can swim and eat after 48 hours.
(3) Young fish reach sexual maturity in about1August, and can reproduce many times a year. Male fish have the habit of protecting their eggs, so they can stay and look after their eggs. It takes about four days for fertilized eggs to hatch larvae, and males can be fished out when larvae swim.
Matters needing attention in breeding red-bellied piranha
1, the water temperature of the fish tank must be kept between 22-28 degrees Celsius and not more than 30 degrees Celsius. To keep the water weakly acidic, it is best to have a constant temperature heating device to filter the incoming water. You can't change too much water at a time, otherwise the unstable water quality conditions will lead to some violence.
2. In the feeding process, it should be noted that the bait should not be too big, and live animals with blood should not be fed. Otherwise, the water quality will get worse and be full of food scraps, which will make them irritable. It is best to choose smaller fish and shrimp to feed, which can not only maintain the water quality, but also prevent them from killing each other because of grabbing food.
3. some equipment such as wires in the fish tank need to be protected, otherwise they will be bitten by their sharp teeth.
