Gerbil waterbottle?

Okay if you have a 10 gallon aquarium for your gerbil or hamster or whatever do you use like a dish for water or a water bottle thing?? i would like to use a water bottle thing but since im getting a 10 gallon aquarium do they make ones that like suction cup instead of just attaching to a wire? I'm pretty clueless in this are and ty in advance!
