There are many fish tanks in the market now, but they are round and square. Generally speaking, it is better to put the fish tank in a round shape on the desk. Remember that the fish tank is not too big. After all, your desk is only that big. If the shape of the fish tank placed on your desk is too weird, it will lose its function of making money.
Many people are very casual when choosing the number of goldfish in the fish tank, and the number of goldfish in the fish tank is also particular. Generally speaking, the fish tanks placed on the desk are not large, so the number of fish tanks is not much.
