In about two days, the temperatures will rise here over 30°C and I have 95 little axolotls, who are now almost 3 months old. I will be gone all day, so I can't keep an eye on them or cool the water if it gets to hot. Is it okay for such young axolotls to be put in the fridge? Ofcourse I won't be able to put all of them in there, but it would be something...
