The Natureform Coral Mini Tube Sponge Yellow/Red, crafted to resemble Theonella sp., is an artificial coral decoration that beautifully combines bright yellow and vibrant red colours. Measuring 10.2 x 9 x 4.5 cm, it is compact enough to fit into tight spaces within an aquarium, making it versatile for various tank sizes. This decorative piece not only adds a splash of colour to the aquatic environment but also provides a low-maintenance option for enhancing the visual appeal of the habitat.
