Scavengers are fish that everyone should be familiar with. It was long black, strange, and often lay in inconspicuous places. Many people think that it can clean up the fish's feces and raise it, which is a misunderstanding: the scavenger is not interested in the fish's feces, the biggest role of the scavenger is to clean the algae on the glass of the fish tank, without the scavenger's fish tank often appears on the inside of the glass long "rust", yellow-brown, attached to the glass, pipe or ornament, this is the brown algae - the scavenger's favorite. The scavenger nibbled on the brown algae and also removed the green algae moss by the way. Therefore, any fish tank with a scavenger basically does not grow algae, and it does not need to be cleaned frequently. I once did an experiment: in a fish tank covered with brown algae, put two scavengers, and the next day it was immediate, and the fish tank was clean.
Some people say: Scavengers are not good to raise! In fact, the scavenger is the best to raise, precisely because it is too easy to raise, so in the fishing grounds can not get good care, always be rough, dense, wounds and diseases are commonplace. As a result, often the scavengers we buy come with injuries and sicknesses. How to avoid this situation? There is a tip: the merchant's fish tank will also grow algae, they will also put a few scavengers to clear the tank, these scavengers are often farmed by the merchant for a long time, absolutely healthy, we choose scavengers in these fish tanks, rather than buying in the scavenger's special tank.
In addition, scavengers are particularly sensitive to fish medicine and salt for sterilization and insecticide, so this situation is often this situation: salt and medicine are sprinkled in the fish tank, the fish disease has not been cured, and the scavenger has returned to his place first.
Some aquarists always like to sprinkle salt on the inside of the fish tank, which is also a misunderstanding, ornamental fish do not use salt without disease, there are disadvantages and no benefits, the most obvious is that they cannot feed the scavengers.
Some people say that scavengers love to chase fish, and when fish are sick, the secretions on the surface of the body will increase, and then the scavengers love to chase the sick fish in order to lick its secretions. Healthy fish don't need to worry about that.
Scavengers with a length of more than 30 centimeters will compete with ornamental fish for fish food, at which point it loses its role in cleaning the fish tank. Therefore, try not to buy an individual scavenger, 15-25 cm is preferred. Scavengers who eat fish food love to swim around dragging long excrement.
The scavenger is a nocturnal fish, so, during the day, we often see it hiding motionless in the corner of the fish tank.
Many customers reported that the scavenger was bitten by the fish, eaten, and only the skeleton was left... I've never seen a fish nibble on a scavenger. But I have seen the scavenger die, automatically decompose within 24 hours, and when salvaged, the flesh and bones are separated with a light touch, and even the internal organs are dissolved, leaving only a skeleton. The scavenger had almost no flesh, and a layer of hard leather wrapped around the skeleton, which was wrapped in a little bit of internal organs. The dead scavengers in the fish tank will not cause the water quality to deteriorate even if they are not salvaged. As nature's cleaner, it seems to consciously solve pollution without bringing pollution.
Don't buy a scavenger in the new fish tank, and then buy it before it is too late to buy brown algae on the glass of the fish tank.
When buying a scavenger, look mainly at its eyes and abdomen, which must be full. Especially the eyes, after the scavenger is sick, the eyes are first sunken inward, and the scavengers whose eyes are sunken are difficult to feed.
Generally speaking, there are two kinds of scavengers, one is black and the other is yellow, and black scavengers are better than yellow scavenger skins.
Many ladies don't like scavengers, hate it for being ugly, and insist on not raising scavengers. As a result, the fish tank glass will be very dirty for a month.
