Good fit for your tank?

Good fit for

  • A mature planted aquarium where you want the size and active grazing behaviour of an Amano shrimp in a much more visible pale form.
  • A peaceful tank with dark substrate and shaded cover that lets the white body stand out without leaving the shrimp exposed.
  • A keeper who wants an unusual individual shrimp and does not need the aquarium to produce a freshwater colony.

Think carefully if

  • The tank contains fish large enough to hunt shrimp. The pale body provides less camouflage than the normal translucent Amano pattern.
  • You want to breed more white Amanos in ordinary freshwater. Their larvae still require a brackish or marine development stage.
  • You are buying without confirming that it is a true pale Amano morph rather than a stressed, freshly moulted, or misidentified shrimp.

A pale or white aquarium-trade form sold as White Amano Shrimp and associated with Caridina multidentata.

Appearance and Identification

Pale, translucent, milky, or white-leaning body colour. The intensity and cause of the white appearance may vary between stocks.

White Amano is a trade label, not a formal taxonomic variety. Confirm that stock is genuine Caridina multidentata and distinguish stable pale coloration from temporary stress, poor condition, or misidentification.

Females are generally larger and broader; mature females often show elongated side markings compared with the smaller dot-like markings common on males.

Behaviour and Tankmates

Peaceful, active grazer that searches hardscape, plants, and substrate for algae, biofilm, and edible organic material.

Not a schooling species, but normally kept as a colony.

Not normally territorial.

Small fish may consume shrimplets.

Water Parameters

Temperature
20–27 °C
pH
6.5–7.8
GH
5–15
KH
2–10
TDS
120–300
Stability importance
Very important

Keep in stable, oxygenated freshwater with mature grazing surfaces. Larvae normally require brackish water, so reproduction does not complete in typical freshwater aquariums.

Parameter caveat
Stable conditions and careful acclimation matter more than repeatedly adjusting water to chase exact values.

Feeding

Diet types
Aufwuchs Grazer, Detritivore, Omnivore
Feeding frequency
Daily
Preferred foods
  • Mature biofilmPrimary grazing resource.
  • Soft algae growthGrazed from aquarium surfaces.
  • Leaf litterProvides grazing surface and decomposing material.
  • Prepared shrimp foodFeed sparingly.

Omnivorous grazer. Provide mature biofilm, algae growth, detritus, and supplementary complete foods rather than relying on nuisance algae alone.

Avoid leaving excess food in the aquarium.

Baby foods
  • Microscopic suspended larval foodLarval feeding and salinity management require a dedicated rearing method.

Females carry many small eggs, but the larvae require a salinity transition and specialized rearing rather than developing entirely in freshwater.
