An aquarium is a container of any size where aquatic plants and animals are displayed. It can range in size from a fishbowl to a whole building. In a dream, an aquarium could represent a safe, yet separated environment for you to observe. Consider your emotions, actions, and the fish or other animals when dreaming of an aquarium.
Positive: Dreaming of fish in an aquarium could represent you being a fisher of men and preserving souls for the Kingdom of God. If you catch fish and place them into an aquarium, it could symbolize that you are saving souls from the world. If you are in an aquarium in a dream it could represent that God is keeping you safe under a covering from your enemies and you should not let anything move you.
Negative: Dreaming of an aquarium that is dirty or dead could represent that you are being confined or not being used to your full potential. It could represent laziness or disobedience.
