Scavenger is a multi-winged Silurus asotus, whose scientific name is "King Alien". It is native to Latin America, also known as sucker fish, trash fish fish and anglerfish. It has a large body and a developed mouth like a sucker, so it is named because it feeds on all kinds of underwater garbage and is often mixed with various fish.

Adult scavengers have a huge appetite. In addition to algae such as moss, they also feed on the eggs of other fish. They can eat 3,000 to 5,000 eggs a day and swallow fry. In the aquarium, it is often adsorbed on stones and glass to stabilize the body and suck algae and moss.

In addition, if the fish get sick, they will stick to their bodies at night and bite their wounds. The garbage collector has a lot of excrement, which is not clean, but will make the situation worse.

Feeding management

Due to the residual bait, debris and fish feces in the scavenger's staple food pond, the feed is mainly put into consideration for the growth needs of koi fish. If scavengers are kept in fish ponds in koi fish, they will start eating in the middle and late April, once a day, according to the changes of weather and water temperature;

The daily feeding amount is controlled at about 2%, and the feeding amount reaches 3% ~ 4% from June, and the feed is placed on one side of the fish pond, that is, on the south or north ridge of the fish pond;

If conditions permit, a feeding machine can be installed to expand the feeding area, which is conducive to the uniform feeding of fish and meet the requirements of neat market specifications. If scavengers are interplanted in fish ponds in koi fish, they should be fed once a day on the second day of stocking in koi fish, and the daily feeding amount should be controlled at 2% ~ 5%.
