Well, I'm planning to buy some Axolotls soon but there's 1 thing stopping me, the temps. I live in a tropical area, so I can only keep the temps at 66F at night when the air conditioner is on. But, what can I do during the day??? I already know keeping the tank on the floor will keep it cooler for a few extra hours, but what about in the afternoon? Buying a chiller is probably my last resort, but can I use some kind of homemade undertank chiller??? Like putting some bags of ice under the tank?(Outside the tank, not the inside). Any ideas?
