I know they can be underwater safely for a while but how long? Also my hornet sometimes gapes while underwater but I feel like it's just his spider gene at work since he does a lot of weird things while taking a bath. He also has some loose skin just at his neck he went through shed but he didn't do it all in one piece it like started at his belly then after awhile he finally started to shed above his belly. His humidity is 60% he has a waterdish that's always full. I know I could rise it, but it doesn't seem like shedding and I've even given him 3 baths but his loose skin is still there on his neck.
