i have them in the bath but the mac i did in an ice cream container
generally i keep it above room temp ( warm but not hot )
but i have found that if you put some branches and other stuff in the water that floats they stay in alot longer
and just throw them in if they dont want to dont force it i have a little girl jungle who wont go, hates going by herself but is fine in a group of 3 or even 2 she even goes under
