Description
7 Hole Barnacle Cave Sandbed Frag Rock Frag Rack for Live Coral Plugs – Phosphorescent Edition
Dimensions: 5″ L x 4″ W x 4″ H
Material: Urethane Resin Infused with Calcium Carbonate & Phosphorescent Minerals
Molded using a real Giant Pacific barnacle to capture the authentic tube structure, surface pitting, and dense natural texture found in true marine growth formations.
Daytime Appearance
Designed to resemble a naturally formed barnacle cave structure, this frag rock provides depth, texture, and realistic reef character. The cave-style openings create shaded pockets for fish to swim through or rest, while the upper surface offers stable placement for coral frags. It blends easily into established reef aquascapes without looking artificial.
Nighttime Glow Effect
Integrated phosphorescent minerals charge under normal aquarium lighting throughout the day. After lights out, the structure emits a subtle blue-purple glow — strongest within the first hour and gradually fading as the night progresses.
• No wiring
• No batteries
• No power source required
• Recharges daily with standard light exposure
The glow adds a unique visual accent while maintaining a natural nighttime reef aesthetic.
Size & Capacity
