Well Happy Halloween to you too, Mrs. Vampire!
But yeah, does depend on the Danios. Usually if they are in a big enough tank, with a big enough school they'll be okay. Up to you if you want to risk getting a devil bunch.

Muhahaha! I think chaning the clocks back the other night has really screwed me up. I keep attempting to eat random people... Not good on the bus.
Will Zebra Danio and Fancy (male) guppies be OK together?
Also, how mature should the tank be before adding the guppies?
