Betta Jet Black 黑色礫石

The color is a deep jet black that really makes my betta's red fins pop, and it didn't cloud the water at all after rinsing. I used it in a small terrarium too, and the grains are uniform enough that it looks clean and natural in both setups.

I was worried the gravel might look too artificial, but the natural jet black finish blends perfectly with my planted tank. It’s smooth enough that my corydoras can sift through it without getting scratched.

The black really makes my red betta pop—I love how the natural gravel doesn't look too artificial. Spreads evenly in my 10-gallon and stays put after rinsing.
