The Red Knobbed Starfish (Protoreaster lincki) is a large starfish for community aquariums. It is a scavenger and carnivore, and is generally not safe for reef aquariums as it may eat some corals, polyps and invertebrates. Red Knobbed Stars will usually have a tan or brown base color with dark red "knobs" across its surface. It is similar to the common Chocolate Chip Starfish (P. nodosus) but has red knobbed instead of the Chocolate Chip Starfish's brown ones and grows much larger.

Starfish in general are very sensitive to changes in water quality and conditions. If temperature, salinity or other water parameters change quickly, starfish cannot regulate the change and are often damaged or killed. Be sure to acclimate carefully and while doing water changes, make sure the "new" water is as close as possible to the "old" water in its parameters.

Most starfish are scavengers. Some may prey on snails and invertebrates while others eat detritus, leftover food, and tiny organisms in and on the substrate and rockwork. Fromia and Linckia starfish are among the group of stars that are considered safe for corals (although Fromia starfish are thought to feed on sponges) and invertebrates while thicker-bodied stars like Chocolate Chip and Bahama stars will prey on snails, corals and other stationary inverts.
