The size of filter will depend on the size tank you get. Once you decide what size tank you are going to get, post a new question on here.....or do a google search for the correct filter size.

Your fish would be fine with rocks, artificial plants (silver dollars will eat real plants), and sand. The sand might end up being a little trouble when cleaning you tank. Rock substrate is easier to maintain.

they get huge! lol
