Also once i get my tank up im going to get a few fish. Am i better off with smaller fish because i would save some money doing so. Ty
If by this you mean buying smaller sizes compared to larger sizes of the same fish, such as a neon tetra, then I usually like to buy the smaller fish. No particular reason, except they are, as you say, less expensive due to the breeder/supplier/store having to feed them less compared to holding larger fish longer, and it is nice to watch them grow up together. On the down side, smaller fish sometimes adapt to different tanks/water conditions less well since they can be more sensitive, and you might lose a few with some species depending upon what you are getting.
The ammonia/nitrite/nitrate numbers indicate your tank is cycling but not done, as the info in the link will explain. How are you cycling? You need to maintain the steady supply of ammonia to keep the nitrification bacteria going.
