There are new fish in the fish tank.

I went back to my hometown these two days. There is a wooden basin at the door with fish in it, which grandpa caught from the river with a net. The fish in the basin are all small miscellaneous fish in the river. The biggest one is a "tiger shark" with black patterns all over it. This is the biggest tiger shark I have ever seen. There are also a few small rays and bream, their tails and yellow ribbons, which are very beautiful. I immediately thought of the fish tank in my city, which kept my pet fish. Five of them are gold and koi fish, which I bought online. So far, I have kept it for more than half a year. Every morning, as soon as I walked into the fish tank, five koi fish suddenly came in. Pushing and shoving each other, my mouth opened and asked me what I wanted to eat. Except for five koi fish, all the others are small miscellaneous fish caught from their hometown river. Among the small miscellaneous fish, there is a tiger shark, but it is not as big as this one that grandpa caught today. The others are all wheat ear fish. There are also two crayfish and a big river shrimp.

I think if I put these fish into my fish tank today, my fish tank will be richer. So I found a bucket and poured all the small miscellaneous fish into it. The biggest tiger shark looks fierce and bumps around. Scared other small fish to run around. I added some more water to the bucket and took it back in the afternoon. As soon as I got home, I immediately poured all the fish and water in the bucket into my fish tank. At this time, my fish tank is richer. After careful counting, there are more than ten fish, large and small. One of them just fell into the fish tank today, and its tail was a little injured. I don't know whether he will recover. Soon, the newly added fish and the original fish in the fish tank came together. The bigger fish in the original fish tank would still bully the new fish. Only the biggest tiger shark has entered the fish tank without fear, so he found a branch to lie down and didn't move much, and no small fish dared to approach it.

When I went to see it again in the evening, the injured small-eared fish had disappeared. Look at two more tiger sharks. The smaller tiger shark, which was originally in the fish tank, has a bulging stomach and a half-injured fish tail in its mouth. The culprit was found and eaten by it. However, the wheat-ear fish is still a little big for it, which may be taken advantage of by it because of injury and can't be swallowed at once. The world of fish is so cruel, big fish eat small fish. All the fish are greedy. They don't feel full. Every time I walk into the fish tank, those cheeky fish are squeezing me, and I am squeezing you, and my mouth is trying to open, as if to say, "I want to eat, I want to eat." "The fish in the aquarium desperately want to eat more and grow bigger. If it grows very small, it will soon disappear and must be buried in the fish's stomach. Some fish are very big, but some are new, some are honest and easy to be bullied by other fish. People often see them scarred. However, every time a new fish comes in, they forget that they have been bullied and bully the new fish instead. Fish cannot have compassion.

I think only the human world will have compassion, although, like eat small fish and the big fish, old groups will bully new companions, and this phenomenon also happens from time to time in the human world. However, people are emotional animals, always encouraging and helping those aspiring newcomers who try to integrate into new groups, and always helping those who suffer disasters. I think this is also the reason why human society has made such rapid progress. Everyone's life is getting more and more prosperous.
