I am currently keeping my newts in a spare bedroom, and it is a little hard to keep them cool in this hot weather, but I find that putting de-chlorinated ice-cubes on the screen and letting them melt and drip into the terrarium is a very good idea, I saw the idea on a website before I bought my newts. I decided to try it, and it brought the water temp down at least 4 degrees! I also have a 10 gallon with a betta, and hopefully two dwarf frogs soon, and then a 30 gallon with Cichlids both in the living room, and then a 20 gallon with more cichlids in our open den area. I am hoping to buy a VERY large (around 100 gallons) for one of my cichlid tanks, they are still babies but getting bigger, but not sure where it will fit! I am most likely going to make my basement like a jungle, as I plan on getting more types of newts, and hopefully some poison Dart frogs!!
