Emerald Crabs Explained
In the scientific world, emerald crabs are known as Mithrax sculptus.These are invertebrates
found in saltwater and they can also become cute little pets in your tank. Crabs of this kind are
considered as cleaners because they eat several things that make the tank dirty such as the bubble
algae. What this crab does is to keep the population of this type of algae to a minimum , just
enough not to harm the water. Pretty much, these crabs are emerald in terms of color. This is
where we get the etymology of the name. These are very small crustaceans because they only
reach up to 5 centimeters as adults.
As far as population of emerald crabs is concerned, it is highly recommended that you only
keep one crab for every 25 gallons of water. If you keep too much emerald crabs in a crowded
aquarium, they will become aggressive and they might hurt each other. These crabs also attack
smaller animals when agitated. Even if they are considered to be safe around snails, there might
still be an attack.
As far as diet is the topic, you can feed these crabs coralline algae. The algae are red or purple
and may be found growing in live rocks. If you will get crabs, you need to acclimate them. Do
not just soak them in the water. You should at least consume an hour doing a slow drip
acclimation method. if you are seriously looking for scavengers for your aquarium, this crab is
one of the best options that you can ever have.
