:OT: good job on trying to get your tank to cycle. i assume that youre a newbie to this hobby. many newbs(such as me a while back) would have just went out set up the tank and plop all their fishes in. make sure to keep up with the water changes and watch the water params to keep the danios at minimal stress
good luck and happy fish keeping
On that note, If you use the Cycle bacteria, which seeds the good bacteria, the ammonia wont spike near as high, keeping the stress levels for the fish down.
