There is an aquarium in my boarding house. Some fishes live inside it, we also put some decoration like stones, synthetic plants, a small statue inside the aquarium. We clean it twice a month, and change the water too. It makes the fishes more healthy. The aquarium stands on the table in the living-room. So, we can always see the aquarium while we are watching the television. In short, we love our aquarium and will keep it as well as we can.
