I wholeheartedly second that - fishless cycling is the best way to go. You'll get several advantages:
- no stressing fish out
- no dead fish (happens sometimes during fishy cycles)
- you'll build up the maximum possible bacterial population, enabling you to put in all the fish at once when the cycle's done
- when friends come over and ask why there are no fish in the tank, you can look at them kinda funny and say 'what do you mean? There are ten or twelve fish in there - you can't see them?'
I just cycled a tank with bio-spira. It costs a little bit, but well worth it. Fishless Cycle and Fish Cycling both take patience, patience I don't have.
I'm pretty sure two danios in a 65g would do nothing anyways.
