Hello everyone! My 20 gallon (tall) tank has been set up with 4 zebra danios for two weeks and one day. I've done one 15% water change during that time because of an accidental fish food spill. Other than that I have left the tank alone and fed the fish a small amount once a day. I test the water every day or every couple of days. I did a full test today with no changes:
High ph: 7.8
Ammonia: 0 (maybe
a bit above zero it's hard to tell, but nowhere near .25)
The fish tank basically tests exactly like my tap water. Are these results normal after the fish have been in there for two weeks? My stocking goal, once things are done, will include 6 zebra danios. I'm wondering if 2 more danios added to the mix would be okay for cycling or if that could make the tank go crazy.
So far the fish are doing great. They all look healthy, are eating well, and swimming around the tank like a bunch of fools. The water is also very clear. Thanks for the help!
