Pom Pom Crab Overview
Pom Pom crabs, with their distinctive physical characteristics and engaging behavior, are a fascinating species in the aquatic world.
These crabs derive their name from the distinctive pom pom-like structures often present on their claws.
Physical Characteristics
The Pom Pom Crab, scientifically known as Lybia sp, is a small-sized aquatic crab, with an average carapace width ranging from 15 to 25mm (0.6 – 1 inch).
The species exhibits a captivating color palette, usually presenting shades of yellow to brown.
Notably, the exoskeleton of a Pom Pom Crab is crucial for protection, but they are also susceptible to shell diseases.
In terms of sexual dimorphism, males and females can be distinguished by size and the presence of reproductive parts.
Behavior and Habitat
Pom Pom Crabs are predominately active and peaceful creatures.
They are known for being less aggressive than other crabs and can often be seen exhibiting a curious behavior, exploring their surroundings.
Their natural habitat spans across regions of Africa, Japan, and Taiwan in both saltwater and brackish environments.
The freshwater Pom Pom Crab, a variety adapted to freshwater conditions, is especially popular in home aquariums.
In the wild, these crabs may be wild-caught but are adaptable to a variety of aquatic settings.
The lifespan and overall well-being of a Pom Pom Crab depend significantly on replicating their natural habitat as closely as possible in captivity.
Care and Maintenance
Caring for Pom Pom crabs requires attention to their habitat, diet, and breeding conditions to ensure a healthy and stimulating environment.
Housing and Environment
Pom Pom crabs thrive in aquariums that mimic their natural habitat.
A minimum tank size of 10 gallons is recommended for adequate space.
The substrate should be a mixture of sand and fine gravel, allowing for easy burrowing.
Including rocks, driftwood, and an array of live plants not only provides hiding places but also encourages the growth of algae, which is a natural food source.
Decorations like caves and climbers cater to their exploratory nature.
Regular water changes and maintaining specific water parameters—including temperature (22-28°C), pH (6.8-7.2), and adequate levels of calcium for shell development—are essential.
Feeding and Diet
As omnivores, Pom Pom crabs need a varied diet including both plant and animal matter.
They typically feed on algae and plant detritus within the tank but will also appreciate a supplement of commercial food pellets formulated for crustaceans.
Live or frozen foods such as brine shrimp and bloodworms are excellent for protein intake.
Their role as scavengers means they will also help clean the tank by consuming leftover food and decaying plant matter.
Health and Breeding
Monitoring the health of Pom Pom crabs includes watching for signs of molting, which is a natural process where they shed their exoskeleton to grow.
During and after molting, they are particularly vulnerable, and their need for calcium increases.
Crabs showing lethargy or lack of appetite may be at risk of disease, such as shell disease.
In terms of breeding, sexing Pom Pom crabs can be challenging.
However, if males and females are present, they may breed in an aquarium setting, resulting in larvae that require specific care to reach maturity.
Keeping tank mates compatible is important, and peaceful invertebrates like snails and cherry shrimp can cohabit well with Pom Pom crabs.
