I have an eclipse 5 gallon tank that I just got. I was wondering what type of setup I should have for Dwarf Puffers.. I know already that they require a lot of hiding spots, but I don't want to get plants as they are high maintenence... Also if I'm living in Arizona and my house temperature is low humitity 80 degrees, do I need to heat the tank or cool it, and will I have high evaporation levels?
