What do fish symbolize in a dream? Fish in an aquarium to be exact.?

I have an aquarium with fish. I often dream about the aquarium, but the dreams alwalys have one thing in common. While there are fish swimming in the aquarium, there are also fish always floating or swimming in the air above the aquarium. And in my dream I am trying to catch them to put them back into the water before they die. The fish are all different types and colors. Ive had these dreams at least 3 times. Anyone know what it could signify?
