Originally, the dormitory was forbidden, pets were not allowed, and even small animals that everyone liked were not allowed to be brought into the dormitory. Some people may keep some animals that will not attack people actively, such as snakes. These animals are enough to make people feel scared. If we want to keep small animals such as turtles or goldfish, and these things are allowed in the dormitory, I think we should ask for your advice.
You can think about it from another angle. If someone keeps an animal that you are afraid of but not aggressive, you may not want to. Dormitory is a place where everyone lives and rests. Pets are just personal hobbies, but they can't be willful. I remember when I was in primary school, one of my deskmates brought a small snake to school. Although the snake is in the bottle, it still makes people feel very scared.
Put these things in the dormitory, and if someone cares, they will feel very uncomfortable. So these animals can be raised by themselves, but it is best not to bring them in the dormitory. If you can, you'd better ask other people in the dormitory for advice.
