Hi,
Have you a test kit for the water? They are a real neccesity at this crucial stage. They shouldnt be considered a luxury when buying a tank, its better to factor them into the cost. To get you started you really need ammonia, nitrite and if possible PH kits or you wont know how safe your tank is for the fish or how the cycling process is going.
I can guarantee you your fish would prefer a test kit to that super cool sunken ship!
