Crabs

57 species

Crabs are a diverse group of crustaceans that can play various roles in a saltwater aquarium. They can be scavengers, algae eaters, or even predators. Popular species include the Emerald Crab (Mithraculus sculptus), which is known for its algae-eating habits, and the Sally Lightfoot Crab (Percnon gibbesi), which is appreciated for its scavenging abilities. When adding crabs to an aquarium, it's important to consider their compatibility with other tank inhabitants and their potential impact on the tank's ecosystem. Some crabs may prey on small fish or invertebrates, while others may help control algae growth. It's crucial to research the specific needs and behaviors of the crab species you are interested in to ensure a healthy and balanced aquarium environment.
