The biOrb Sea Fan is inspired by the delicate sea fans of Indonesia. Create natural security for your fish while allowing them to be viewed among the stems. These colorful sea fans would be a natural accent piece to your Saltwater biOrb. Use with the biOrb Sea Lily to compliment a biOrb aquarium sculpture. The small plants are suitable for all biOrbs and are 7.87 inches / 20 cm in height.
