If your using a glass tank, you can easily fashion a waterbottle holder out of hardware cloth, and hang it on the side so it doesnt matter what bottle you use. I have done that for many of my ASF's bottles, and they worked very well. The only thing to make sure is they cant sit on top. It just annoyed me to clean poo and pee off the top, so I made it as close to the top of the lid as possible.![]()
