matty-two: help for leafcutter ants (29. Jul 2016 20:29)

Hi guys I'm eighteen years old I'm french and I'm new in this forum
For one year and a half, I was looking in diferents website informations about leafcutter ants... But I always have some interrogation about theirs breeding.
In first: Is it a good idee to put the foragment area in an aquarium with water (anti évasion) in the case of I'll be in hollydays...? I know that some ants will die but does it represent a lot of ants or is it "admissible"?
For the humidification does a drinking trough or balls clay are more than enough?
The A****re nest have 27mm holes. Is it too small?
And the last one, what is the better system for keep the grad to 22-27°C ?
