Heterometrus Longimanus Enclosure Downsize

[jnmnj3]

I currently have an adult asian forest scorpion in a 10 gallon tank (20" L, 10" W, 12" H) with 6" of substrate. I want to know if I can move him into an extra large critter keeper (15 3/4" L, 9 3/8" W, 12 1/2" H). My main concern about this is that the critter keeper is about 5 inches shorter length-wise (about 5.9 gallon capacity instead of 10). Basically I live in a small apartment and have a scorpion and a tarantula, I'm a very anxious person in general and tend to catastrophize about some sort of emergency. I know it's irrational to expect a disaster, but having the scorpion in a plastic enclosure that is lighter and easier to move/evacuate with would make me a lot more comfortable. I also expect to move sometime in the near future and it just seems easier with a plastic enclosure (also the critter keeper would match to my tarantulas enclosure). Regardless, the scorpions comfort is more important to me so I will keep the glass tank if its for the best. Is the xl critter keeper too small for the scorpion?
His current enclosure has a shallow water dish in the middle and a hide on each side: one of the hides he is in 98% of the time and has dug a very deep burrow (used all 6 inches of substrate and gone all of the way to the glass on the back of the enclosure), the other hide he has only dug out a little and rarely uses. He does rome around the tank a bit at night sometimes. I think the critter keeper could be appropriate because my scorpion really only uses half of his 10 gallon and it still allows for 6+ inches of substrate but I wanted to hear some other opinions. If you think it's too small, are there any plastic alternatives to a 10 gallon tank? I haven't been able to find anything as most display cases and such are not that large. I'm not a fan of storage containers because they are not completely clear. I'm probably being way more concerned about this than I need to be but it feels weird rehousing into a smaller enclosure. Thanks

TLDR: my asian forest scorpion is in a 10 gallon tank (20" L, 10" W, 12" H) and I want to rehouse him into an extra large critter keeper (15 3/4" L, 9 3/8" W, 12 1/2" H). I am concerned because it is smaller than his 10 gal.

When I choose an enclosure, I think of it this way.

If you can fit four to five exact size scorpions in there together, how much space left?

That’s how much space I would give, safely saying.

In the wild, that is all they want. Other aspects of the enclosure mean nothing to them. They roam for two reasons, bug hunts and mating. If food is abundant they stay put. Nothing you can do about the mating wandering.

I can almost guarantee you it's actually H. silenus, not longimanus. There are VERY few in the country and you'll find zero at pet stores, unless you got it from a private breeder that really specializes in scorpions specifically. 99% of the time an Asian Forest Scorpion is being sold regardless of what they label it as, it will be an H. silenus

Also, don't be concerned. I keep more Heterometrus and Pandinus species than maybe anyone in the US, they thrive, eat, and breed no problem in shoebox style tupperware bins. In the wild they spend 95% of their loves in deep, moist burrows and only come out if they're pretty hungry, looking for a new female colony/kicked out of their old colony, or their burrow got destroyed. It's way too dangerous outside of the burrow to just "go for a stroll" so to speak lol. So when they do, it's for a reason. They honestly feel safer in less open areas
