saw all the posts about how to attach water bottles. we buy ones that have hook to go over tank but we just save those if we need them. we use the metal hanger that comes with them all. i just drill 2 holes in side and attach the hook. no matter if our syrians try to climb they cant make it. though our cambells male is a huge chewer and chews bottles so he got the oasis bottle that is kid friendly. only bottle he dont destroy yes i mean destroy...
plus its vaccume powered.... no leak love it. hers link to it same as before drill hole for holder but use the metal holder or suctions... under $5 at petco in us
