First time molters, and pet sitting

[Scat20]

I’ve had my 3 hermit crabs for about a month, all fairly small-medium sized. About a week ago the 2 fairly larger and more active of the 3, buried tunnels down, I was informed on molting so I’ve tried not to disturb the substrate. My mother has asked me to pet sit/ house sit for a week my only concern is I’m properly caring for them. So I have another smaller 20 gal tank that I have set up for the right conditions (substrate, humidity, soaking dishes, decor, etc) I feel bad having to move just 1 hermit by himself so I can take him with me so he can be properly cared for leaving the other 2 for the week. Or do I absolutely need to dig up the other 2 and bring them. I think that would cause more stress them letting them be for a week which I believe them to be molting??? First time crab mom here and I would love some advice on this. Mainly my concern being what do I do with my 2 molters? As this is their first molt.

If the two crabs that are molting just went own then they should be good for a week but I'm not sure what I would do with the third one that's not molting. Maybe take him with you with the other tank set up just to be safe? But I would not recommend moving the other two.

I have routinely left my crabs for a week at a time, a few times a year. Just be sure that the water pools are full and stable, and feed them dried foods. When you get back, the food will be fuzzy and moldy, but it isn't harmful - just throw it out and put in new stuff.
