I am setting up a small tank just to house 1 male betta. Firstly, in my other tanks I use gravel as a substrate, but would sand be an option in this one? If so, would just the normal kids' playsand do, or does it have to be anything special from my LFS? If I added it would the water go cloudy and for how long? And would sand affect my betta in any harmful way?
