Ok, you definitely need those tests down the line anyway. If your tank is totally cycled you should get the following readings
Ammonia = 0 ppm
Nitrites = 0 ppm
Nitrates = 50 ppm
Ammonia and Nitrites are both really bad for fish. Here's how the nitrogen cycle works....
Ammonia is converted to nitrite by one species of bacteria. Then nitrites are converted to nitrates by another species of bacteria. Nitrates are usually removed by water changes which you should be doing every 1-2 weeks. Change out about 20% of your water. You can probably do a ten gallon water change.
When you test, if you find any ammonia or nitrites I would do a large water change, maybe 20 gallons or so.
