A few weeks ago I lost my lovely Pacman frog Waka. I didn't realize how cold she was getting, one morning when I woke up ... he/She just didn't

I am really debating trying again. I am so afraid to kill another. I don't know how to go about keeping the little one warm. My turtle experience is really not helping me here since if I set up a basking bulb it would make the humidity plummet.

Please help ... both with deciding if I should try again and if I do, How to keep the little one warm.
