How to deal with the fish tank after throwing the roe of koi? How to deal with the roe thrown out?

If there is no male fish, then the koi should clean and disinfect the fish tank after throwing the seeds, and then open the tank again. Because the roe is thrown to the bottom of the tank, it is easy to cause water quality deterioration, and the female fish is weak after spawning, if not handled in time, it is easy to be life-threatening. If there is a male fish, the female fish should be fished out first, and the semen produced by the male fish should be put in, so that the fertilized eggs can be formed. Then the fertilized eggs can be directly fished out and hatched in a new container.

1. How to deal with the fish tank

after throwing the seeds of the koi 1. Fish out and change the water: If the koi is not paired, it is necessary to fish out and throw away the seeds as soon as possible after spawning. Because only female fish can not form fertilized eggs, it will not only pollute the water quality over time, but also easily breed bacteria. If you can fish out all the fish roe, you don't need to clean the fish tank, just change the water frequently.

2. Brush the tank: If the fish roe sticks to the bottom or wall of the tank, it is necessary to brush the tank for cleaning. You can first change the koi into a new container, then pour out all the water, brush off all the roe, and finally disinfect it with potassium permanganate solution. After cleaning, the water will be re-maintained. When changing the container for Koi, it is better to choose the same water quality and temperature as the original tank. Because the koi is weak at this time, it is easy to feel uncomfortable when the environment changes too much.

If there is a male fish, you can try artificial ejaculation, gently press the abdomen of the male fish with your thumb, squeeze the semen into the fish tank, and let the roe form fertilized eggs.
2. If there is no male fish, you need to fish it out and throw it away or feed it to the snails and shrimps, because shrimps and snails prefer to eat fish eggs. You can also leave some for Koi to eat by themselves. Be careful not to leave too much. It is easy to pollute the water quality if you can't finish it.
