Koi and what kind of fish are raised together, the master teaches you how to choose an aquarium

1. Selection of aquarium

(1) in terms of materials, domestic aquarium materials are usually made of glass and acrylic, the former is of heavy quality and poor resistance, but the price is cheap, while the latter has relatively light quality, good light transmittance and resistance, but the price is expensive.

(2) in terms of specifications, the aquarium for breeding koi is relatively large, and the specifications available on the market are usually 90cmx45cmx45cm, 120cmx45cmx45cm, etc., and can also be customized according to the requirements of buyers.

two。 Configuration of Aquarium equipment

A complete aquarium needs to have life support systems such as aquatic animals and plants, including filtration system, lighting system, temperature control system, oxygen enrichment system, disinfection system and so on. The most important of these is the filtering system.

There are three main filtration methods in the aquarium: biological filtration, mechanical filtration and chemical filtration.

Filter materials: filter cotton, activated carbon, sand and gravel, biofilter ball, etc.

3. Selection of koi and stocking of healthy and lively individuals

As follows

(1) from the fish body surface, the fish body is clean, there is no thick mucus attachment, the fins and scales are intact, and the eyes are bright.

(2) from the perspective of swimming posture: swimming freely, the fish body is coordinated, showing a lively swimming posture, can quickly hide or escape when stimulated by the outside, and the stress is high.

(3) from the point of view of bait, it is quick to grab food, flexible and strong appetite.

4. Daily management

(1) bait and feeding method

① natural bait or artificial compound bait with natural brightening substance added.

② is twice a day, once in the morning and once in the afternoon.

(2) Water exchange and cleaning

Change the water regularly according to the specific conditions of the aquarium. In general, the water should be changed every 15 ℃ 20 days, and the total amount of water should be changed every 15 minutes. The difference is no more than 1.5 mol. Adequate aeration and filtration should be ensured before new water is injected.

(3) Lighting

Light is an important environmental factor for koi to keep its color bright and grow healthily. Secondly, light is very important for the transformation and regulation of water quality. It is best to reach 3m / m / d for 4h.

(4) other management measures

Maintenance of aquarium filtration system: the filtration system with sponge and activated carbon as the main filter material needs to be cleaned or replaced from time to time. Usually, activated carbon 2muri is changed once every 3 months.

Summer management of aquarium culture: the temperature is higher in summer. In general, when the water temperature of the aquarium exceeds 30 ℃, there will be "heatstroke" phenomenon, and the water temperature is high, and the fish will speed up the deterioration of water quality, so the frequency of changing water and absorbing pollution should be increased appropriately in summer.

5. Aquarium set

Mainly fish, stone, grass and so on.

(1): lay the bottom sand, after the aquarium is cleaned, spread the cleaned sand at the bottom of the aquarium, about 4-5cm thick.

(2): put rocks and decorations, choose a well-shaped rock as the main stone, close to the position of the main stone can put a few small rocks as a foil, at the same time with some small decorations.

(3): when planting aquatic plants, you can directly insert them with a small shovel or hand-dug hole, then bury them in sand, or plant them in a small pot, and then put the flowerpot into the aquarium.
