When choosing the perfect location for your fish tank, you need to consider both the type of fish you have and the size and weight of the tank itself. The shape of the aquarium and the size of your room are also essential considerations as you want to place it where it can be easily viewed and accessed without getting in the way. And if you have heaters or filters, the tank needs to be in easy reach of any electrical sockets you may need. However, be cautious about placing your tank near to a window or heat source, such as a radiator, especially if you need to keep a consistent water temperature inside your fish aquarium. And too much direct sun can encourage algae to grow inside the tank, which will eventually murk up your aquarium water.
