Compared to what? This is kind of unknown because of so many other variables, but I definitely think sand is less abrasive for teeth, the rest is for genetics and diet to decide

Well, unless you compare it to other festae, ideally siblings, in a gravel tank, you will get inconclusive results. But if you see your festae teeth larger then normal, then the sand theory gets a +1 haha.

Worth a shot, I'm not sure how to test the teeth though, not sure cons teeth are visible... Guess your going to have to get bit![]()
