Welcome and congrats on the new frog! I feel your pain about the heating situation. I can't put a very large heating pad on my temporary quarantine tank so I've also kept mine in the bathroom for a while, checking on them in the night. Eventually I found that a heat lamp with a100 watt ceramic heat emitter suspended over the tank (combined with a small space heater nearby) worked well. It does dry out slightly more easily, but at the same rate it would with just about any heat source. I spray down the tanks before I go to bed and they're still at an acceptable level in the morning. Maybe an extra-large water bowl would help keep up humidity a bit. Do you have any kind of substrate in there to hold moisture right now? I hate to suggest spanum moss because it's an impaction risk, but if you feed from a bowl the frog is less likely to accidentally ingest the stuff. Edit: Okay, I'm not battling Alberta level cold- apparently the solution I gave you is what you're already doing without success.It's late and things have stopped making sense All I can really suggest for heat is maybe a slightly higher wattage lightbulb?
