Hi could you mail me please because I really wanna start a salt water tank but am to scared because every one says how hard and scary it is I have a 20 gallon tank.
A fish only tank isn't much different than a freshwater tank imho. You just have to pay closer attention to nitrates and phosphates not to mention the cost difference. A reef tank can be quite a bit more difficult however.
