This is the same #12 finger claw sponge only smaller and on a base. measures 3.5"x3.5"x10.5" tall. Can be made in any color as a solid piece or with the coralline purple custom base. The neon colors will glow under a UV source. Excellent for reef tanks and seahorse aquariums. made of a very durable and nearly unbreakable urethane composite safe for all aquariums fresh or saltwater. Get them in multiple colors.

Enjoy!!
