Is it okay to put the fish tank on the windowsill and look directly at the door?

The fish tank can be placed on the balcony, due to the effect of light, the color of the fish will be very good, but the water will grow green algae or brown algae, and the algae will consume the oxygen in the water, so it should be cleaned up in time. It is better to add a scavenger (which can reduce the trouble of wiping the jar). Note that the temperature difference between the morning and evening balcony will be very large, which is not good for the fish, and the water should be kept at a constant temperature (buy a constant temperature heating rod).
