I've always noticed that my betta tanks smell like garlic. The smell gets especially strong during water changes. I mentioned it to my friend and she said that her tanks smell like garlic, too. Does anyone else have this problem? What is it? Is there any way to make it go away? 

What do you put in the water?

Maybe it will remain an unsolved mystery? It just seems odd that both of my bettas have it and now so do all of yours. Other than the stink they all seem healthy and happy though~
