Jumping Danios?

[eybic]

I recently got a 58L Aquarium which is unheated (around 20 degrees) with some White Cloud Mountain Minnows. I want to get some Danios but am worried about their reputation for being jumpers.

To do any maintenance other than feeding, I need to remove the hood. Does anyone have experience with Danios? How justified is their reputation? I'd probably have 6 or 7 in the tank.

Thank you
