A wide variety of fish can be found at an Aquarium; such as squid, octopus, jellyfish, penguins, polar bears and etc.They each live in a confining "fish tank". They are given enough food and always kept in the proper temperature.Also, there is no worry of being attacked by predators.If they get sick,they can get immediate medical attention.However,since they are in a confined apace, they can't live without human's treatment.The sonfining "fish tank" also plays a role in some kind of showcase at the aquarium.Bright lights and explanation panels are attached to complete the "living exhibition".

We can seldom see them in their natural state.How do they feel living there? It makes me wonder how moral it is to force animals to live in a man-made world like the aquarium.
