You just need to let them all acclimate.... And when you wanna put them together just go out and buy a 55-75 gallon rubbermaid and convert it. I'm through with buying cages, rubbermaids work equally as well... You could buy two rubbermaids....and stack them. 55 gallons each! I'm buying radiant heat panels and hooking them up when I make the switch. A heat pad on the bottom, and the heat panel up top. Perfect for humidity, perfect fr function. And one hell of a home.
