?fish, also known as manta rays, is similar to the sharks that appeared in the Jurassic period of the Mesozoic, and has the ability to hide in the sandy seabed habit. If aquarists want to raise fish, they should first understand the type of fish to be raised and the environment in which they are raised, in order to better raise this fish. Follow the pet editor to learn about it!

1. Fish (stingray) breeding environment

1. The size of the fish tank:

The size of the fish tank depends on the It depends on the size of the fish. It is generally believed that the fish likes stable water quality, so the bigger the fish tank, the better, but if the fish is small or young, the predation ability is usually poor. Feed them to help them hunt and thrive.

2. Filtration efficiency:

Fish are carnivorous big stomach kings, and the excretion volume is quite considerable. Only a filter system with powerful filtration efficiency can handle this pollution quantity. So we can use both upper and outer filters and use them to maintain long-term feeding. Bottom filtration will agitate the bottom sand so it is not suitable.

3. Water quality environment:

The pH of the fish tank should be maintained at 6.0~7.5, the nitrate content of the fish tank should be maintained at 100-300mg/L, and it must be soft water with a color of water. It is transparent water with high oxygen content.

4. Lighting equipment:

It is best to use plant lights for the lighting of the fish tank, and the number of lamps should not be too many. The lighting time is 8~9 hours. Sexual fish prefer dim lighting.

5. Water temperature control:

The water temperature of the fish tank is between 26 and 32 degrees Celsius, which is an acceptable range for most species. The fish may die suddenly. If the water temperature of the fish tank is too low, the resistance of the fish will be reduced and it will be easy to get sick.

6. Bottom sand suggestion:

The bottom sand is recommended to be placed in the initial stage, and the thickness of laying is about 0.5~1cm. The finer the particles, the better, and the texture is neutral sand The most suitable, one can stably reduce the oppression of new fish, and one can allow the fish to adapt to the environment early, but after about 2 months, it is best to remove it to facilitate water quality control.

7. Fish tank decoration:

Basically, there is no need for artificial decoration, and general natural decorations such as rocks, sinking wood and aquatic plants are actually redundant decorations. Suitable for fish.

2. Skills for raising fish (stingray)

1. Mixed fish species:

Will bite and lick the body surface of the fish , fish with hard thorns on their bodies, hard stab wounds and viscera after predation, fish that are naturally quiet and easy to be rioted by fish, and small and easy to be preyed on. They are not suitable for polyculture.

2. Types of bait:

The fish are completely carnivorous fish, such as goldfish, scallops and other small fish, or red worms, cut fish, etc. They are all eaten. Among them, their favorite is red worm, no matter what kind of fish they like to eat. The only thing to note is that individuals with a body disc diameter of more than 30cm rarely eat only red worms, so be careful.

3. Food intake control:

Generally speaking, if the fish body plate diameter is less than 15 cm, the amount of red worms in a day is about 10 grams. An individual with a body disc diameter of about 30 cm can eat 4-5 goldfish a day.

4. Fish diseases:

The main cause of fish diseases is almost always caused by rapid changes in water quality. The surface will grow a layer of obvious white mucous membrane. In this case, if it does not recover in a short time, so that its resistance becomes weak, the chance of death is great.

5. Frequency of water change:

It is recommended to change the water regularly, which is also the most convenient and effective way to slow down the pH drop and reduce the nitrate concentration. Because the nitrate concentration does not produce acute toxic reactions to fish, long-term exposure to an environment where the concentration is too high will cause stress to the fish and increase the risk of disease.
