Decor Glass Marbles Pack of 1

Glass Marbles for Aquariums are a decorative and fish-safe substrate option made from inert, non-toxic glass. Their vibrant colors and reflective surfaces add visual appeal to any tank setup while ensuring water chemistry remains stable. Ideal for hobbyists looking to enhance aesthetics in betta tanks, shrimp bowls, and small decorative aquariums. While they offer a stylish look and easy cleaning, they are best used in tanks that do not rely heavily on planted substrates or biological filtration from the substrate.
