The General Starfish, Pentaceraster sp., is a thick bodied starfish that comes in many different colors. It has characteristic bumps, often of different colors than the limbs, radiating from its center disc along the tops of its limbs. Colors can vary from browns, to yellows, and greens. They are quite sensitive to changes in the tank environment so be careful when changing any parameters and be sure not to expose the General Star to air. They are scavengers but can prey on snails and corals as well.
