Mithraculus sculptus

Mithraculus sculptus: Emerald Crab

The Emerald Crab (Mithraculus sculptus) is a striking crab species found in the coral reefs of the western Atlantic, particularly in the Caribbean. It is characterized by its bright green coloration and long, thin legs, giving it a spider-like appearance. This crab lives in close symbiotic relationships with the coral reefs, often hiding on rocks or in crevices, and feeds on algae and detrital matter. It is an excellent algae eater and helps control algae growth in aquariums. In addition, it includes bubble algae in its diet, consuming them and further contributing to algae regulation.

Aquarium care: The Emerald Crab is a peaceful species that can be kept in an aquarium with at least 100 liters of volume. It requires hiding places, as it often retreats into them. Since it feeds on algae, it is particularly useful in reef aquariums, where it helps control algae. It is important that the aquarium maintains stable water parameters and is cleaned regularly. This species is relatively easy to care for as long as the aquarium environment meets its needs.
