The aquarium

📖 In short

An aquarium is a place where we keep fish and water animals to watch and enjoy. It can be a small glass tank in your room, or a huge building with enormous tanks where sharks and turtles swim.

🤩 Did you know?

  • A tank of 38 to 76 liters is good for beginners.
  • Most tropical fish need water between 22 and 27 degrees.
  • Part of the tank water should be changed regularly to keep it clean.
  • Don't put too many fish in a small tank.

🌟 A little home underwater

A tank needs clean water, gravel on the bottom, water plants, a filter to clean the water, a little pump to add air, and a lamp to light it.

🔍 The right temperature

Some fish like cold water, like goldfish, while others need warm water, like colorful tropical fish, so we give them a little heater.

💡 Don't overfeed them!

We give fish a little food once or twice a day. Extra food stays in the water and spoils it, and the fish can get ill.

🎯 Big aquariums

Big cities have huge public aquariums where you sometimes walk through a glass tunnel, with fish and sharks swimming over your head!
