The Emerald Crab (Mithraculus sculptus) is one of the most popular reef-safe algae-eating crabs in marine aquariums. Known for its striking green color and small size, this crab is highly effective at controlling nuisance algae, especially bubble algae.
It spends most of its time picking algae from live rock and hard-to-reach areas, making it a valuable member of any reef tank cleanup crew.
Benefits:
- Eats bubble algae and film algae
- Helps maintain clean live rock
- Reef-safe when well-fed
- Small and active cleaner
Care Notes:
- Provide stable reef environment
- Feed if algae is limited
- Avoid aggressive tank mates
- Keep in mature aquariums
