If the bubbles in the fish tank are difficult to disperse, you need to improve the filtration of the fish tank first, clean the filter cotton, and pay attention to changing the water at the same time, so that the bubbles will gradually dissipate.The reason why there are bubbles on the water surface is due to eutrophication of the water body, or because the water quality is unstable, which leads to this situation, because there is more feed in peacetime, so controlling feeding is the best solution.
1. Too many fish: The number of fish should generally match the size of the fish tank. If the fish tank is not large, there are many fish. In this way, excrement and body surface secretions will pollute the water quality, resulting in a large number of bubbles in the water body.Therefore, it is necessary to keep fewer fish or change to a larger tank.
2. Large amount of feed: As mentioned above, too much feed is the main cause of bubbles on the water surface of the fish tank, so it is necessary to control the amount of food.Usually, it is better to eat it within 5-10 minutes after feeding, if there is feed sinking to the bottom of the water, it needs to be cleaned up as soon as possible, so as to prevent bad water.
3. Female fish spawning: When the female fish reaches the breeding period, even if it does not mate with the male fish, it can still spawn. However, this kind of fish eggs will not hatch and will only slowly decay in the water. In this way, the water quality will be affected.Therefore, after discovering the big belly of fish, it is better to put a few false aquatic plants, wait until there are fish eggs attached, take them out and clean them up.
