Pisces USA Betta Aquarium Jewels are a fun way to add some color to your aquarium. The Betta Aquarium Jewels are made from recycled glass, tumbled and polished like beach glass, that adds color to your aquarium.
Despite the name, they’re great for tanks besides Betta aquarium — a small aquarium, goldfish bowl or anywhere else you’re looking for a fun substrate. Since they are glass, they’re inert and won’t change the water chemistry.
These are available in six colors — emerald, ruby, ruby swirl, sapphire, winter frost and violet — to give you a few options to create a unique look. The Aquarium Jewels retail around $6.95 for a 17 oz. bag.
