May be a scavenger

In large shopping malls, there are always several fish tanks at the entrance and exit for decoration. The red, green and green fish play between the plants, and the dragonfly is beautiful. However, I don't know if you noticed it. It is the ugliest fish that is attached to the cylinder wall. It is called a scavenger.

Compared with other fish, blood parrots, heads, silver, and other beautiful goldfish, the scavenger is really ugly: the stupid body, the scales are large; the small tail is not as charming as other fish; The bad thing is that it doesn't eat anything all day long, eating some dirty things, people can't help but feel a bit disgusted. Before I really understood it, I wanted to vomit as soon as I saw it.

Later, the family raised a few fish, including a yellow small scavenger. It and a lot of beautiful fish in a big tank, always look so ugly, so nondescript, I hate it the most, don't want to see it every time.

But since I raised it, I found that my father never changed the water in the tank. Curious, I ran to the side of the fish tank and watched it carefully. Hey, it turns out that the scavenger is cleaning up the water! I saw it with a mouth - say a mouth, in fact, a small suction cup with a translucent color - sucking a water grass, and swallowing the dirty things in a short time, the water grass is clean. After doing this, it swayed its tail and sucked it onto the cylinder wall. I have to be awesome to it.

In the two months after the incident, the goldfish died one by one, and only the scavenger was left. It grows very fast, it is already a big fish, and has a group of children. I put them in a bigger tank and went to see it every day. The scavenger led a group of babies, happily doing the work, and rubbing the water transparent as glass.

I am ashamed. At the same time, I also think: grow up to be a person like a scavenger, beauty in the heart, not in appearance, do not care about success or failure, silently serve others.
