I tore down my planted tank and dirted it today, what's the over/under on adding the fish back?

It's a 20 long. I have 10 white cloud minnows, a few celestial danios and three pygmy cories currently at summer camp in a bucket with a sponge filter. I am trying to decide if I should leave them there and replace a gallon a day or chuck them back in the tank and watch ammonia like a hawk. I have a RO filter so water changes are no problem but I just can't decide which approach is best.

And yes, I know this could have all been prevented with better planning. Let's just stipulate that that ship has sailed.
