I am the type of person who likes to make a cool setting and have a pet live in it. I made a huge rain forest setting for my frilled dragon, and its fascinating. I have a 40G long tank that I want to set up with a few colorful newts that are compatible. When I look at the care sheets, they all say that I need a hood on the top, but my 40g has a screen top. So my question is... does it really matter that much? Secondly... anyone know of some neat looking newts that are compatible?
