We were in a big store, Costco maybe, and there was a fish tank that already had 2 little fish in it, and some how a SHARK, the shark was not harming the fish, but would attack us.  The whole dream, we were trying to add another little fish, but the temp had to be just right, not only for the fishes survival but also for the shark not to attack our fingers.  Finally, my husband was able to cool the tank down enough for me to put the little fish in.  But, I lost the fish, I looked everywhere for it, and remembered, I put it in my shirt pocket, I put the fish in the tank and it jumped up with joy and swam around.  

That was the end of my dream....

Right after I woke up, I remembered the movie, Soul Food, where Big Mama said, dreaming of fish means someone in the family is pregnant..
