Ocean Aquaria Nine Tube Sponge – Artificial Coral for Fish Tank & Aquarium Decor #644 (Purple/Pink)

Nine Tube Sponge – Artificial Coral for Fish Tank & Aquarium Decor – #644 Dimensions: 7″ x 5″ x 6″ Material: Durable Urethane Rubber This piece was molded using a real dead tube sponge to ensure the most accurate representation possible. Tube sponges naturally grow in clustered formations made up of multiple upright tubes that extend from a shared base. Each tube typically varies in height and diameter, with slightly irregular rims and subtle surface texture along the outer walls. This replica captures that natural arrangement with nine individual tubes grouped together, creating a layered structure with depth and open space between the columns. The varying heights and organic spacing give the piece a realistic reef presence while maintaining the distinctive cylindrical openings that define sponge colonies. At 7″ x 5″ x 6″, it works well as a mid-sized vertical element within an aquascape, adding height without taking up excessive footprint. Made from solid, reef-safe urethane rubber with no added fillers, this coral is built for full submersion and long-term durability. It will not leach, degrade, or affect water chemistry, making it safe for fish, invertebrates, and live rock systems. Established in 2001, Ocean Aquaria has been producing realistic artificial coral for over two decades, focusing on accurate molds, safe materials, and long-lasting durability trusted by hobbyists, public aquariums, and professional installers. Available in multiple color options. If you need a specific tone to match your reefscape, custom requests are always welcome. Care Note: Rinse with warm water and gently clean with a soft brush as needed. Do not use bleach.
