I like these for our tanks. They look nice with the gravel and are easy to clean. They give of a nice glow when the tank light is on and I've found them in several colors and reasonable prices. I also use them in my plants for decoration.

Cons: No Complaints

These are a really nice alternative to gravel. My daughter loves to change the decor in her Betta bowls and these gems have worked beautifully. They are very easy to keep clean and come in a variety of colors.

Pros: Great selection

Cons: none

I also used these in some of my tanks. Sprinkled on top of the gravel they are very pretty. They are very easy to tke out and clean.
