Instead of a boring, uniform floor, these small 2.8-ounce packs allow you to layer textures using multicolored gems, marbled gray stone, or vibrant pink pebbles. I found that mixing the blue, green, and clear pebbles creates a much more dynamic backdrop than standard gravel alone. It is specifically designed to catch the light alongside GloFish plants and ornaments, ensuring your neon fish aren't just swimming in a dark void but are instead part of a coordinated, glowing ecosystem.
