be added? As long as the feeding density of the fish tank does not reach the upper limit, new fish can continue to be added. However, it should be noted that not all fish can be raised together, and it is better to understand the rules of polyculture before putting in new fish. Generally, only fish of similar size can be chosen for polyculture, and the requirements for water quality and temperature are the same. If big fish and small fish are raised together, small fish are likely to be eaten.
to the fish tank 1. Disinfection: If you add new fish to the fish tank, you must first disinfect it. If the new fish carries harmful bacteria, it will soon have a negative impact on the old fish in the tank, and may even lead to its death. Therefore, it is necessary to prepare some potassium permanganate solution, and then put the fish in it and soak it for a period of time to kill the bacteria on the body surface.
2. Overheating: Fish are poikilothermic animals and are extremely sensitive to temperature changes. Therefore, new fish often need to be overheated before entering the tank. The method of overheating is very simple, just put the fish bag into the fish tank, the heat of the water will be transferred across the bag, so that the water temperature in the tank and the bag is gradually consistent.
3, water: After the completion of the temperature, but also to the fish water. Scoop out one tenth of the water from the bag, pour it into the tank, and then scoop out the same amount of water from the fish tank and pour it back into the bag, so that the fish in the bag can gradually adapt to the change of water quality, exchange every ten minutes, usually after five times, the bag can be taken away.
