Common name: Starfish

Valvatida is an order of starfish found in a variety of marine environments. They are known for their diversity in size, shape, and color, with species ranging from the iconic five-armed sea stars to those with multiple arms. Valvatida includes both reef-safe species, like the Fromia monilis, and those that are not suitable for reef tanks due to their predatory nature on corals and other invertebrates. Hobbyists should research individual species for compatibility. These echinoderms are fascinating for their ability to regenerate lost limbs and their role in marine ecosystems as both predators and prey.
