After discovering that there is oil film in the fish tank, the first thing to do is to change the water in time. Whatever the composition of the oil film, it will affect the healthy growth of fish, so we need to collect the oil film on the surface of the water body into a cup, then pour it out, and then add water to it. Water must be added to the drying water, the new water is easy to stimulate the fish body.
There are many reasons for the formation of oil film, but most of the time, oil film comes from fish feed. The main component of oil film is protein, and fish feed itself is rich in a large amount of protein, if the content is too high, resulting in fish can not be completely digested after eating, it will be excreted. By replacing the feed with a slightly lower protein content, the possibility of oil film formation can be reduced.
In addition to changing the feed, we should also pay attention to reducing feeding. If too much feeding produces residual bait, it will gradually form an oil film on the surface of the water body. Usually can increase the feeding interval, a few days or a week to feed once also does not matter, the fish itself is more hungry. Each feeding should be finished within one minute, and there should be no residual bait.
Not only the bait can produce oil film, but also the filter, but this situation is not common, only when the filter material is particularly dirty, oil film will appear. At this time, the oil film should be sucked out of the water outlet with oil absorption paper, and the filter barrel should be cleaned at the same time. It should be noted that the filter material should not be removed and cleaned, which can easily lead to the death of fish.
