I've had tropical fish all my life (litrally) but have never actually experimented having anything but silly little fish. When I last went to the fish shop to buy a new pump they had a stingray for sale in the marine section and I just wished I could have something more interesting and exiting then fish for once. I know I wont be able to get a marine tank because they take a lot of work so is there anything interesting that I could have in a tropical fish tank?
