Marine Crabs

Marine crabs can serve several roles in saltwater aquariums:

• Cleanup Crew: Many crabs help control algae, detritus, and leftover food, keeping the tank clean.
• Sand Aeration: Some species, like fiddler crabs, sift through the substrate, preventing harmful buildup.
• Ecosystem Balance: Certain crabs contribute to the biodiversity of the tank, interacting with other marine life.
• Aesthetic Appeal: Their unique behaviors and striking appearances add visual interest.
• Predator Control: Some crabs help manage populations of small pests, like bristle worms.

However, not all crabs are reef-safe—some may prey on fish, corals, or other invertebrates. If you're considering adding crabs, it's best to research species compatibility first.
