Looking into getting a pacman for my twenty gallon long. I don't have much experience with frogs. I did have a couple green tree frogs about 10-12 years ago. My main question is about lighting /heating. There are allot of varying opinions on the subject. Is a heat mat on the side of the tank or wrapped around a corner of the tank ok as a lone source of heart? Some say it is as they do not require any specific lighting and the heat put off from the lighting can dry them out. I'd like to gather your guys and gals experiences and preferences so I can make the best decision for myself. If it helps, I live in eastern Pennsylvania and in my house the temps range from 66 in winter to 74 in summer... Thanks in advance for your help!
