Description
Large land hermit crabs are known as Coenobita brevimanus. Because of its relatively uniform purplish body colour, Coenobita violascens is frequently confused with this species. It can also occasionally be brownish-red, though. These hermit crabs can be distinguished from other species of the same genus by their excessively big left claw with no stitch marks. Round eyes with brown to black eye stalks are present.
Distribution
East coast of Africa and the south-west Pacific Ocean are the native habitats of Coenobita brevimanus. Currently, this species can be found all over the Indo-Pacific region. East Africa, the Philippines, Indonesia, India, Japan, China, Malaysia, and Taiwan are among the places where these hermit crabs have been found.
Behavior
Due to their nocturnal habits, Indonesian crabs spend the majority of their waking hours hiding from the light. They genuinely come to life at night, exploring the tank in search of food or a new hiding place. Once they are comfortable, they will act more extrovertedly and venture outside more frequently, even throughout the day. Since they are regarded as social creatures, these hermit crabs thrive when left alone. Their lives become richer and less stressful as a result.
Keeping as Pet
Tank Size (Enclosure):
Coenobita brevimanus is a big species, to start with. These hermit crabs require a lot of room to manoeuvre. Just keep in mind that even if they aren’t particularly active during the day, they more than make up for it at night.
One little hermit crab should have a minimum of a 10-gallon (40-liter) tank. Large people measuring 3 to 4 inches (7 to 10 cm) will need a tank that is at least 30 gallons (120 litres) in size.
Temperature:
Coenobita brevimanus does well in a temperature range of 80 to 90 °F (26 to 32 °C). They do prefer warm weather. They grew lethargic and their movements slowed down significantly at lower temperatures.
Humidity:
The level of humidity is crucial. The abdominal lung of the Coenobita brevimanus is tailored to its terrestrial existence. They therefore require wet, moist air to breathe. There should be more than 70% humidity in the air. The ideal range would always be between 80 and 90%.
Diet:
The amount of meat-based diets in the food should be somewhere between 20% and 80% of the total, along with a lot of vegetables and cellulose-rich foods. Keep in mind that hermit crabs only communicate individual food preferences. Additionally, they frequently change their behavior when eating strange foods. To stay healthy, Coenobita brevimanus needs nutrients including carotene, astaxanthin, calcium, and even antioxidants. Food variety is crucial for this reason.
