Emerald crabs (Mithraculus sculptus) are a popular addition to marine reef aquariums because of their attractive appearance and useful role in controlling certain algae. However, aquarium keepers often wonder if these helpful creatures are totally safe for their reef in the aquarium.

Algae Control in Aquarium
One of the main reasons why aquarists choose Emerald crabs is their ability to control algae, including ones like Valonia ventricosa. These crabs are also known for consuming other types of algae which can be problematic in reef aquariums.
Compatibility with Other Inhabitants
Emerald crabs are usually calm towards other aquarium inhabitants. However, like most crabs, they can become aggressive if they are hungry or if space is limited. This can pose a threat to small, slow-moving creatures.
Size and Conditions in the Aquarium
The size of the aquarium and environmental conditions can significantly affect whether Mitrax crabs will be safe for the reef in the aquarium. Larger aquariums with plenty of hiding spots and enough food can minimize potential dangers associated with keeping Emerald crabs.
Providing Food
If natural food sources are limited, it’s recommended to regularly feed Emerald crabs to minimize the risk of aggression towards other aquarium inhabitants. Special crab food and a varied diet can help keep them healthy and happy.
Conclusion
In conclusion, Emerald crabs can be a safe and beneficial addition to reef aquariums, provided appropriate care and monitoring. Their natural tendency to control algae can be beneficial, but it’s also important to provide enough space and food to avoid potential problems. It’s also good to regularly observe interactions between Emerald crabs and other aquarium inhabitants to make sure they coexist harmoniously.

Reefkeeping has been my passion for over 10 years now. I love learning. The hobby has taught me many valuable lessons, patience being the best example. Combining work and passion is my path. I run Crazy Coral, a marine aquarium shop, for a number of years. Building this business from the scratch I learnt from my own mistakes at a heavy cost.
Later I managed a project aimed at development of methods for quick growth of Corals in non-natural conditions. The project was carried out by Get Sales, Poland. Presently, I am responsible for distribution strategy at Reef Factory, of which I am a co-founder. The company produces smart devices for marine aquaristics. The last projects I have been involved in are Social Reef and ReefPedia.
