I soaked mine when she had a problem shed, her's was coming off in pieces and she ended up with a retained eye cap. Luke warm water, half an inch - inch deep supervised soakingOr you could let him run through a damp towel in your hands. If he looks to be having difficulty I would assist although more experienced keepers may tell you to wait a little while.
I offer food as scheduled whether they are shedding or not, if they're hungry they'll take. He may not eat as he is in shed but I don't see any harm in offering.
Can't help with tank size as I only have little BP's ranging from 60g to 550g(empty) so I am useless there for you but there are some great guys on here who can help you with that!
Hot side should be 88-90 which I see you have. Great! Your cold side needs bumped up a few degrees. 70 is too low, I'm afraid! You need a minimum of 74 farenheit. Ideally you are looking for 74 to 78 cool side (correct me if I'm wrong guys)
Humidity sounds great. His bad shed could be due to stress of the new place, nothing to worry about though! Hopefully next shed will go better as he'll be settled right in
Great that you're getting a thermostat. How soon are you going to have it? A UTH without one is quite dangerous as those mats can reach astounding levels of heat and cause burns!
If the tank is fully glass suggested to cover three sides for added security if not already done as they can feel very exposed.
Hope to have helped a little bit![]()
