Freshwater Pom Pom Crab at a glance
Adult size: 0.7 inch · Minimum tank/pond: 10 gallons · Difficulty: intermediate · Diet: omnivore · Lifespan: 2-3 years.
Freshwater Pom Pom Crab (Ptychognathus barbatus) is a freshwater invertebrate kept by aquarists for planted-tank cleanup crew + breeding-line collecting. Suitable for keepers with 6-12 months of experience and stable water chemistry.
Where Freshwater Pom Pom Crab comes from
Freshwater Pom Pom Crab (Ptychognathus barbatus) is native to freshwater habitats across multiple continents. The captive-bred Freshwater Pom Pom Crab sold at most LFS comes from generations of farmed stock and is generally hardier and better-acclimated to tank conditions than wild-caught equivalents. Wild specimens are occasionally available for keepers chasing original-bloodline coloration or biotope-accurate stocking.
Freshwater Pom Pom Crab tank size and setup
Freshwater Pom Pom Crab requires a minimum of 10 gallons for healthy adults. The minimum is based on the species' adult size (0.7 inch), territorial range, and behavior pattern. Most Freshwater Pom Pom Crab sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Freshwater Pom Pom Crab setup: mature planted tank or low-stocked community tank with stable parameters, mineralized substrate (or remineralized RO/DI for Caridina), low-flow filtration that does not suck up shrimplets, and minimal copper exposure (avoid copper-treated medications).
Use dechlorinator on every water change. Test parameters weekly during cycling, biweekly once stable. Stable consistency beats sliding-scale "ideal" parameters.
What Freshwater Pom Pom Crab eats
Freshwater Pom Pom Crab is a omnivore. Eats a varied diet of pellets, frozen foods, and supplemental greens. Quality flake or pellet (Hikari, New Life Spectrum, Tetra) plus frozen mysis or bloodworms 2-3x weekly produces best color and behavior. Feed Freshwater Pom Pom Crab appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Freshwater Pom Pom Crab tankmates and compatibility
Freshwater Pom Pom Crab works alongside peaceful community fish. Avoid mixing with fin-nippers (some tetras, barbs), aggressive cichlids, or large predators. Best in shrimp-only or mostly-shrimp tanks for breeding success - any larger fish will eat shrimplets.

Freshwater Pom Pom Crab adult size and lifespan
Freshwater Pom Pom Crab reaches 0.7 inch at adulthood with a captive lifespan of 2-3 years with proper care. Females carry eggs under the abdomen until hatch; in stable tanks, breeding populations sustain themselves indefinitely.
Can you breed Freshwater Pom Pom Crab?
Yes - Freshwater Pom Pom Crab is one of the more readily-bred freshwater invertebrates. Most freshwater snails self-fertilize and reproduce continuously in stable tanks; some (nerites) require brackish water for egg viability.
Common Freshwater Pom Pom Crab diseases and problems
Freshwater Pom Pom Crab is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Freshwater Pom Pom Crab for 4 weeks before adding to your display tank. Treat fish in a separate hospital tank to avoid affecting plants and inverts. Most disease outbreaks trace back to poor water quality, chronic stress, or skipped quarantine.
