I would check those nitrates just to be certain. 20ppm is the safe max for most all the fish we keep [I know, people will say up to 40ppm, some even higher, but this is just not safe] and below 10ppm is best. Some floating plants will help with this, they are easy, unless you have nitrate in the tap water. That requires a different solution.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
