Creating hiding spots in the form of caves or plants is beneficial for freshwater Pom Pom crabs. It provides them with places to retreat and feel secure within their tank.

Tank Accessories

Essential tank accessories such as sponge filters, Matten filters, aquarium pumps, inert substrates, and decorations can be used in the setup.

Freshwater Pom Pom crabs are excellent climbers and may attempt to escape if given the opportunity. To prevent mishaps, ensure your tank is securely sealed at the top, lower the water level, and hide any cords they may climb on.

Following these guidelines can provide a suitable environment for your freshwater Pom Pom crabs to thrive.

Behavior and Temperament

Freshwater Pom Pom crabs are incredibly active and not timid. They are more active than most crab species and can often be seen wandering around the tank, scavenging for food. These crabs may dig burrows or create small mounds using substrate materials.

Occasional fights or aggression can occur, especially towards smaller co-inhabitants. However, they are among the least aggressive crab species to most fish and generally coexist peacefully with other tank inhabitants. Males may occasionally display to each other, but it rarely results in injury.

Molting is an essential process for freshwater Pom Pom crabs…

Molting is essential for freshwater Pom Pom crabs, and they dig burrows to molt safely. During molting, they become vulnerable and need calcium to mineralize their new shell. They hide in caves or burrows to protect themselves while developing a new exoskeleton.

Tank Mates

Freshwater pom pom crabs, Ptychognathus barbatus, can coexist well with various peaceful co-inhabitants in freshwater aquariums.

Compatible: Freshwater pom pom crabs are compatible with other generally peaceful fish species such as tetras or guppies. These fish tend to have a calm temperament and will not pose a threat to the crabs.

Coexistence with Other Creatures: Pom pom crabs generally get along well with other generally peaceful, freshwater inhabitants like crabs, snails (except very small snails), and shrimp.

Species to Avoid: Very Small Snails And Other

Notably, these crustaceans can be opportunistic eaters (may go after very small snails). Therefore, it is advisable to avoid keeping vulnerable creatures with them.

Avoiding aggressive or fin-nipping fish when considering tank mates for freshwater pom pom crabs is crucial. Any species large enough to prey on these crustaceans should also be avoided.

When setting up an aquarium for your freshwater pom pom crab and its potential tank mates, ensure suitable conditions for all inhabitants. Consider water chemistry, live plants, algae growth, appropriate substrate, and a secure lid.

By carefully selecting compatible tank mates and creating an environment that meets their needs, you can ensure a harmonious coexistence for your freshwater pom pom crab and its companions.

Food & Diet: Protein Rich Frozen Foods And Others

Freshwater pom pom crabs are scavengers and opportunistic omnivores with a diverse diet. They have a diverse diet of algae, plant detritus, small insects, and organic matter. Vegetation may be part of their diet, but they do not eat live plants.

Supplement their diet with sinking pellets or flakes and protein rich frozen foods for proper nutrition. These can be fed to them in small amounts once or twice a day.

Although freshwater pom pom crabs have filter fans attached to their claws, these are not used for filter feeding. However, the fans sometimes catch food particles that the crabs consume.
