I have finally decided that I am going to sell all my fish and my tank so I can get a different size when I move house, as I haven't got the money to get another on whist I still I have the one I have but I think it will be the best desion to do 
+1 I'd also keep the tank. Save the money you have and then look at your options later on.I would just keep the tank you have, save and transfer your current fish once you've got enough money for a new tank.
