Welcome.

The tank isn't cycled at all unless you set it up with substrate or filtration that came directly out of a long established tank.

Read up on nitrogen cycle here. You can run with what you got, by keeping some zebra danios in there like you are. Feed very lightly and keep up on regular/often water changes. Do you have something to test water parameters with? What dechlorinator are you using?

Tank will be not cycled in 3 days, tank cycling will take up to 6 ish weeks.
What are your readings for ammonia, nitrite and nitrate?
Do a 75% water change.
