Vampire Crab Size & Growth Rate
The average size of a Vampire Crab is 1.5-2 inches, but they can get up to 3 inches wide.
They grow at a moderate rate and can reach their full size in 2-3 years. If you want to keep a juvenile Vampire Crab, you will need a tank size of 10 gallons or more. As they age, they become more docile and less active.
Vampire Crab Lifespan
The typical Vampire Crab’s lifespan is 2-3 years in captivity. This is the same for both males and females.
In the wild, Vampire Crabs can live up to 5 years. And their lifespan is determined by the amount of food they can scavenge.
Vampire Crab Appearance
The most interesting thing about Vampire Crabs is their appearance. They have two large fangs that protrude from their mouths, giving them a vampire-like appearance.
They come in a variety of colors, including orange, red, green, and blue. They have black spots on their shells, which help to camouflage them in the wild.
They have 10 legs, and their front legs are much larger than their back legs. This helps them to climb and scavenge for food. While most crabs have powerful claws, Vampire Crabs have weak claws unsuited for fighting. The color is brightest on a Vampire Crab’s claws, used for defense and to help them climb.
Typically, the body of a Vampire Crab is about the size of a quarter. It may be small, but it’s one of the coolest-looking crabs.
Creamy white spots on a Vampire Crab’s legs help it camouflage in the wild. On top of their heads, they have two black antennae that they use to feel their way around. These antennae are also used to communicate with other crabs.
Vampire Crabs have gills that allow them to breathe underwater. These gills are located on the underside of their body and are covered by a flap of skin.
Males and females look virtually the same, except that males are typically a bit larger than females. This can make it challenging to sex Vampire Crabs unless you have a trained eye. However, there are a few ways to tell the difference. One way is to look at the shape of their abdomen. The abdomen is more rounded in females, while it is more triangular in males.
Another way to sex Vampire Crabs is by examining their genital pouches. In males, these pouches are large and triangular, while they are small and round in females.
Vampire Crab Behavior & Temperament
These crabs are nocturnal creatures that prefer to stay hidden during the day. They are very active at night and often climb on things in their enclosure. They are not aggressive towards humans or other animals. However, they will fight with other Vampire Crabs if they feel threatened.
These are social creatures and should be kept in at least 3 crabs. They are very active and playful animals. They will often play with each other.
Vampire crabs are easy to care for and make great pets for children and adults. They are an excellent choice for anyone looking for an exciting and unique pet.
They will roam the tank freely during the night. If you have other pets in the house, you should make sure that they cannot get to the Crabs. This is because the other pets may harm or eat them.
Vampire Crabs are not demanding and do not need a lot of care. They are an excellent pet for someone who does not have time to care for a pet.
Vampire Crab Breeding
Vampire Crabs can be bred in captivity. They are a very easy species to breed and make an excellent starter crab for new crab owners.
To breed, you will need to provide them with a tank of at least 10 gallons in size. The tank should be filled with plenty of hiding places, so the crabs can feel safe. You should also provide many different types of food so the crabs can breed.
They are most likely to breed in the spring or summer months. To increase your chances of breeding them, you can keep the tank at a temperature of about 80 degrees Fahrenheit.
The female vampire crab will lay her eggs in a safe place. Once the eggs hatch, the baby crabs will be on their own. Vampire crabs do not provide any care for their young. We recommend that you remove the young crabs from the tank once they have hatched. This will help ensure that they survive.
These Crabs make great pets for both children and adults. They are a fun and exciting addition to any home and bring hours of enjoyment. If you are looking for an unusual pet, then this Crab may be the perfect choice for you!
Vampire Crab Care
Vampire Crab care is relatively easy, and they can be kept with other docile species of Crab. Unfortunately, the lack of aggression also means that they are not very hardy and can die if mishandled.
They are semi-terrestrial crabs, which means they spend part of their time on land and water. Because of this, you will need to provide both land and water area in their tank.
To create a land area, use moss, coco fiber, or sand. You can also use small ceramic house ornaments to help your Crab feel at home.
You will need to provide a wet and dry area for their water area. The wet area should be filled with fresh water, while the dry area should be filled with salt water. If you do not have access to both types of water, you can use a water conditioner to make the freshwater salty.
Keep the water levels consistent in both areas, and change the water in the wet area every day.
As mentioned earlier, Vampire Crabs are semi-terrestrial crabs. This means they need both land and water area in their tank.
For a single Crab, you will need a tank size of 10 gallons or more. If you plan on keeping multiple Crabs together, you will need an even larger tank.
Remember to always provide plenty of places to hide, as they love to burrow. You’ll see many owners use coconut husks, moss, or other types of live plants to achieve this.
It’s important to ensure that the water in your tank is filtered and maintained properly. Due to their unique semi-terrestrial lifestyle, they are very sensitive to water parameters.
- Water Temperature: The water temperature in your tank should be around 70°-82°F.
- pH Level: The pH level in your tank should be maintained at a level of 7.0-8.0
- Ammonia Levels: Ammonia levels should be kept at 0ppm or below.
- Nitrite Levels: Nitrite levels should also be kept at 0ppm or below.
- Water Changes: It’s essential to change the water in your tank every week, or even more often if needed. As you can see, taking care is not as difficult as it may seem. With a little bit of knowledge and some basic supplies, you can thrive in its new home.
It is important to keep the water in your Vampire Crab’s tank properly filtered. This is especially important because they are very sensitive to water parameters.
There are a number of different types of filters you can use for your tank.
Some recommended filters are:
- Canister Filters: Canister filters are a great option for tanks up to 125 gallons.
- HOB Filters: HOB filters (stand-alone) are good for tanks up to 55 gallons.
- RO/DI Systems: If you use salt water in your tank, you will need to install a RO/DI system. This will ensure that the water is kept at the correct pH level and free of harmful toxins.
No matter which type of filter you choose, clean it regularly. A good rule of thumb is to clean your filter every two weeks.
When it comes to a substrate, you have many different options. The most important thing to remember is that these crabs are very sensitive to chemicals. This means that you need to avoid substrates that contain chemicals or have been treated with chemicals.
Some recommended substrates for vampire crab tanks are:
- Moss: Moss is another good choice for vampire crab tanks. It is natural and chemical-free, and it helps to keep the humidity levels high.
- Live Plants: Live plants are a great way to add greenery to your tank. Not only do they look nice, but they also help to keep the humidity levels high.
- Sand: Although not as common, and can also be used as a substrate for tanks. Just be sure to avoid any sand that has been treated with chemicals.

There are a number of different ways to increase the humidity level in your tank.
Some popular methods are:
- Mist your vampire crab regularly. You can use a spray bottle filled with water to mist your Crab.
- Place a humidifier in your tank. This will help to increase the humidity level in your tank.
- Add some live plants to your tank. Live plants help to keep the humidity levels high.
One of the best things about Vampire Crabs is that they are very small, so you don’t need a lot of decorations in their tank.
We recommend using live plant sand or driftwood to decorate your tank. This will provide them with some shelter, but it will also help keep the humidity levels high.
Some popular live plants for vampire crab tanks are:
- Java Fern: Java Fern is a hardy plant that does well in low light conditions. It is perfect for tanks.
