We are extremely proud and excited to be likely the only North American retailer to offer the freshwater Pom Pom Crab (Ptychognathus barbatus), a true gem and consummate nano aquarium specimen!  This extremely rare freshwater crab has proven to be a very endearing, interesting, and durable candidate for the freshwater community aquarium.  Very little information is available for this crab, but we have done extensive research to determine proper husbandry for this crab in our in-house facility.

Like most crabs, the Freshwater Pom Pom Crab is an omnivorous scavenger.  In addition to eating food items that collect on the patches of hair (“pom poms”) that grow on its claws, it feeds on filamentous algae and detritus in the aquarium and will also readily accept high-quality dry foods that are rich in plant matter.  We also occasionally feed these crabs protein-rich frozen foods such as bloodworms, but only sparingly.

The Freshwater Pom Pom Crab reportedly has pockets of population throughout many tropical and sub-tropical regions in Africa, Asia, and Australia, particularly Madagascar, Taiwan, and New Caledonia.  It inhabits both brackish and fully freshwater areas and it is suspected that this crab spawns in brackish water and its fry go through a larval stage similar to many crustaceans that live in freshwater as adults but spawn in brackish areas.  Spawning in the aquarium has not yet been reported.  Unlike most “freshwater” crabs, this crab is truly fully aquatic.  However, we recommend keeping your water line relatively low or keeping a lid on your aquarium, as these crabs are occasional escape artists.

This crab is peaceful towards snails and fish from what we have experienced but it may go after dwarf srhimp.  It is much heftier, active, and more outgoing than the peaceful Thai Micro Crab (Limnopilos naiyanetri), and for the most part it shares the same disposition. There have been instances where certain individuals have shown aggression towards dwarf shrimp so they may not be safe to keep with dwarf shrimp all of the time.  But overall this crab will make for a completely ideal, exciting candidate in any nano, community or planted aquarium.

* It’s important to note that this is a very small crab (most will be 1 inch or less at the time of purchase but they can grow up to 1.5 to 1.75 inches). This small size makes them ideal for nano tanks as mentioned above *

 

*IMPORTANT* Please "Choose a Variant" above before adding this crayfish to your cart. We offer a "B-Grade" variant for these crabs. Our “B-Grade” crabs are simply specimens that are missing legs or claws unless otherwise stated. Some may also be missing the "pom poms" as well. Loss of appendages is not permanent and happens commonly with crustaceans.  They are completely healthy with excellent coloration and will completely regenerate lost appendages within 1 to 2 molts.
