Common name: Decorator Crabs

The genus Schizophrys belongs to the family Majidae, commonly known as spider crabs. These crabs are often referred to as "Decorator Crabs" due to their fascinating behavior of adorning their carapaces with bits of algae, sponges, and other materials from their environment. This camouflage not only helps them blend into their surroundings but also provides protection from predators. The genus is primarily found in tropical and subtropical marine environments, often inhabiting coral reefs and rocky substrates.

In the aquarium hobby, species within the genus Schizophrys are occasionally kept by advanced aquarists who appreciate their unique appearance and behavior. However, they are not as commonly available as other marine invertebrates. These crabs are generally peaceful but can sometimes be opportunistic feeders, potentially nibbling on soft corals or small invertebrates if not well-fed. They are best suited for larger reef tanks with plenty of live rock and hiding spaces. Their diet in captivity should include a mix of meaty foods and algae to mimic their natural omnivorous feeding habits.

From a scientific perspective, the genus Schizophrys is intriguing due to its ecological role in marine ecosystems. By decorating themselves with living organisms like algae and sponges, these crabs contribute to the biodiversity and complexity of their habitats. This behavior also makes them a subject of interest in studies on animal camouflage and symbiosis. Hobbyists interested in keeping Schizophrys species should ensure stable water parameters and a well-established tank to meet their needs.
