Small Chinese aquarium in our house

Assalamu Alaikum. How are you all Alhamdulillah I am fine.

We have a small aquarium at home. The aquarium is a Chinese aquarium. This aquarium is not very big. Seven to eight small fish can be kept in this aquarium. Two to three large fish can be kept. But if you keep more fish, the fish will die. I kept a lot of fish a few days ago. Many of my fish died then. I went to the fish shop and talked. That's why my fish are dying. Then they told me that according to the size of your aquarium you keep enough fish. Then your fish found will not die.

According to the shop owner I currently have eight small fish in my aquarium. I have three species of fish here. The fishes are small and medium in size I bought fish food for one year. Fish do not need much food. People decorate the aquarium with different plants and rocks. But my aquarium is arranged in a normal way I put some white stones inside the aquarium and put plastic plants. And I have a filter in my aquarium. Sometimes I do filtering. Sometimes I clean my aquarium. Uncle's aquarium is cleaned once to twice a month. Iron accumulates if not cleaned. Then the aquarium looks bad

It is nice to have an aquarium at home. I like to see the movement of the fish. It looks very beautiful from a distance when the lights are turned on at night. It's been three to four years since I got this aquarium. So far there have been no problems with the aquarium. But so far I have bought many fishes. In fact, fish do not live long in the confined space of the aquarium.
