100 Degree Ambient Temp? Fatal or not?

[kitedemon]

You should be fine. There are a boat load of people that own balls with unregulated UTH's and heat lamps that keep hot spots over 100 all day, every day. Balls are quite sturdy animals and a lot of people tend to freak out when we stress their optimal husbandry.

Ambient and Hs temps are 100% different game. Keep an eye on them and allow temps to return to normal. Naturally don't try to shock them down. As Jen said make sure there is enough fresh water for them and keep an eye on them for any issues. Hopefully they will be ok. they can manage higher than optimal temps for short periods so they my be ok. Did the hot spot shut down (tstat that is)?
