Get the largest wheel you can fit in your aquarium, because they need the exercise and large diameters don't hurt their spine. Niteangel is a quality brand for all hamster/gerbil accessories and they make large wheels. No wheel is silent, though. My kid wants the gerbils in her bedroom, but turns the wheel so it faces the glass wall so the gerbils don't use it at night and disturb her.
Also, you'll see a lot of sand marketed towards hamsters, gerbils and chinchillas. Only chinchillas actually need their dust baths, hamsters and gerbils don't really, and indeed, their respiratory tracts can't handle too much fine dust, and neither can humans'. So if you want a sand bath for your gerbil, don't put it in the cage all the time. Give them a sand or dust bath once a week for a few hours, and that's it. There are different grades of sand: the coarser kind is safer for respiratory tracts because neither they nor we can breathe it in, but it doesn't do much to keep them "clean". The fine dust sand is perfect to keep fur clean, but it's not good to breathe in. So use in moderation.
OP here
Hamsters actually can have sand baths all the time, with Robos needing at least 1/4 of their cage to be sand. it is fine as long as you use a calcium-free, undyed reptile sand, like zoomed reptisand. Hamster can't have baths, so they use the sand to clean their fur. never use dust/powder though.
