Do Emerald Crabs Eat Hair Algae
If you’ve ever noticed little green beads clinging to your aquarium glass, rocks, or plants, you were probably looking at hair algae. This type of algae gets its name from its long, stringy appearance that resembles human hair. While many aquarists consider hair algae to be a nuisance, it can actually provide a valuable food source for some animals in your tank.
One of these animals is the emerald crab. Emerald crabs are voracious eaters of all types of algae, including hair algae. In fact, they will often spend most of their time picking through the tank in search of something to munch on.
Not only does this help keep your aquarium clean and free of unsightly algae growths, but it also provides an important source of food for the crab. If you have an emerald crab in your tank and you’re noticing an increase in hair algae growth, don’t be alarmed – this is perfectly normal! The crab is simply doing its job and helping to keep your aquarium healthy and clean.
Do Emerald Crabs Eat Aiptasia

The short answer is yes, emerald crabs will eat aiptasia anemones. In fact, they’re one of the few animals that will actively seek out and consume these pests. If you have an aiptasia problem in your reef tank, adding a few emerald crabs is a great way to get rid of them.
Just be sure to add enough hiding places for the crabs so they don’t become prey themselves!
Emerald Crab Care

It’s important to offer them a variety of foods so that they get all the nutrients they need. Housing: Emerald crabs can live in both freshwater and saltwater tanks; however, most people prefer to keep them in saltwater tanks since that’s their natural habitat.
When choosing a tank for your emerald crab , be sure it has plenty of hiding places and climbing surfaces as these crabs like to climb and explore their surroundings. A 10-gallon tank is sufficient for one or two crabs , but if you plan on keeping more than that , you’ll need a larger tank . As far as filtration goes , an emerald crab can live in either a standard filter or a hang-on-back filter system .
Just make sure the flow isn’t too strong or else it will stress out your crab . Lastly , don’t forget to add some marine – safe sand or gravel to the bottom of the tank for your crab to burrow in ! Common Health Problems : Like any other pet , emerald crabs are susceptible to certain health problems .
The most common problem seen in captive emerald crabs is shell rot , which is caused by bacteria living on the surface of the shell .

White spot disease can be very deadly if not treated immediately with fresh water dips or medications designed specifically for treating parasites .
Are Emerald Crabs Aggressive
If you’ve ever wondered if emerald crabs are aggressive, the answer is yes and no. It really depends on the individual crab and its mood. Some emerald crabs can be quite docile while others may become agitated and even attack other fish or inverts in the aquarium.
So, it’s really a case-by-case basis when it comes to these little guys. That said, there are certain things that can trigger aggression in emerald crabs. If they feel threatened or cramped in their living space, for example, they may lash out at other tank mates.
Overcrowding is often a major contributor to aggression problems in aquariums, so it’s important to provide plenty of hiding places and open space for your crabs to roam. Another common cause of aggression is hunger. Emerald crabs are scavengers and will consume just about anything they can get their claws on – including live food!

Once the new exoskeleton hardens, the crab will be back to its usual self.

They are opportunistic scavengers in the wild and will consume just about anything they come across, including dead fish, algae, detritus and even other small crabs.

A good quality marine flake food or pellet can form the basis of their diet, supplemented with frozen foods such as mysis shrimp or brine shrimp. Vegetables such as blanched spinach or zucchini can also be offered occasionally. It is important to offer them a variety of foods to ensure they are getting all the nutrients they need.
