What is it?
This is an aquarium with tropical freshwater fish. The fish are probably from warm rivers and lakes in places like South America or Southeast Asia. They might be cichlids, a family of fish known for their bright colors and interesting behaviors. The aquarium has water, plants, and maybe rocks to make the fish feel at home.
How old?
Aquariums have been around for a long time. People started keeping fish in glass tanks in the 1800s. But the fish in this tank are alive today, so this is a modern exhibit.
What was it like?
The fish swim in clean, warm water. They have space to move and hide. The tank might have a filter to keep the water clean and a heater to keep it warm. The fish eat special food and live together in a group.

This aquarium shows us the beauty of freshwater life. It helps us learn about biodiversity—the many different kinds of fish and other creatures that live in rivers and lakes. It also reminds us to take care of our water and protect the environment.
