Yes, tiger sals do well in a moist terrestrial environment. I kept 2 awhile ago, but ended up giving them to my friend because she has a permit to own them and they are actually illegal in my state to own..!
I had mine in a 20g-long tank, screen top. They did well off of crickets (dusted with Repti-Vite every other feeding or so.) They were so funny; they'd wait for a crick to go by, and then grab it, and shake their head like a dog grabbing a shoe or something!
I also fed mine reasonably-sized nightcrawler worms. Mealies are great too. I always used the Eco-Earth brand of coconut-husk bedding for mine. They love to burrow (they are "mole salamanders" like Spotteds, which is why they are not often seen in the wild unless you lift up a rotting log or something.) I also had a Very Shallow water dish in that they could soak in (like a tea-set plate.) It also helped with humidity, but I misted the tank regularly and kept plastic wrap over most of the lid.
I would probably keep any future ones in a tub. Humidity retention is a cinch, and cleaning is easier.. I didn't know about tubs as housing for herps back when I had mine!
I would add in fun things like large native rocks for them to hide behind. Moss, soft fake plants (harder ones could hurt their delicate skin.) Their skin is porous like frogs, but I do remember mine sipping water (frogs don't do that, they absorb water through their skins, but sals can do that also.)
