Snakes with a wobble gene will always have some form of wobble, even if it is hard to see. Wobble will be worse when stressed and in a new environment most of the time. Leave them alone for 1-2 weeks and only bother them to give water. Make sure you lower your temps to around 86-88°F on the hot side. Lower temperatures can keep wobble from being as bad. Don’t be surprised when you go to handle them and they wobble because they are freaking out over new things and getting stressed.
Is that aspen bedding in there with your snake? I would recommend removing that and replacing it with either paper towels or newspaper if you want to monitor for RI a lot easier. Even if you don’t want to monitor for RI, get a bedding that holds more moisture so it doesn’t dry up in there. Aspen also does have a tad bit of dust, even though it isn’t much, so you may wanna try something with zero dust since some snakes are more sensitive than others to things like that. But I wouldn’t ever recommend aspen for a species of snake that needs it to be humid. Also, how long did you leave the snake alone after you got them? And how often did you try feeding?
