Good fit for your tank?

Good fit for

  • A breeder who likes irregular red-and-white patterns such as zebra, skunk, spotted, or broad Pinto patches.
  • A mature low-KH Caridina aquarium where different pattern types can be separated into their own breeding groups.
  • A keeper who sees varied offspring as part of the appeal rather than as a failure of the line.

Think carefully if

  • You want a uniform colony with identical red markings. Pinto offspring frequently display several pattern types and grades.
  • You do not have room to separate breeding groups. Mixing all patterns together makes targeted improvement much slower.
  • The tank contains fish, strong filter intakes, or little biofilm, all of which reduce survival of the small and valuable young.

A red-and-white hybrid Caridina line selected for bold Pinto spotting, striping, and head patterns.

Appearance and Identification

Red base colour with white pinto, zebra, skunk, spotted, or broken pattern elements.

Red Pinto is a hybrid aquarium pattern line rather than a recognized species. Its exact ancestry differs between breeder lines.

Adult females are generally larger and deeper-bodied than males. Colour and pattern intensity are not reliable sex indicators.

Use a mature, cycled aquarium with active substrate or another stable soft-water setup, gentle filtration, abundant biofilm, mosses, leaf litter, and protected filter intakes.

Behaviour and Tankmates

Peaceful dwarf shrimp that graze biofilm, algae, detritus, leaf litter, and prepared foods.

Best maintained in a group with other compatible Caridina lines sharing the same water requirements.

Not normally territorial.

Peaceful community fish may still eat shrimplets. Keep breeding colonies in shrimp-focused aquariums. Different compatible Caridina lines may interbreed and alter colour or pattern outcomes.

Water Parameters

Temperature
20–23 °C
pH
5.5–6.5
GH
4–6
KH
0–1
TDS
90–140
Stability importance
Very important

Keep in soft, acidic water with near-zero KH. Active substrate and carefully remineralized reverse-osmosis water support stable conditions.

Parameter caveat
Stability matters more than chasing a single number. Avoid abrupt changes in temperature, pH, GH, KH, or total dissolved solids.

Feeding

Diet types
Aufwuchs Grazer, Detritivore, Omnivore
Feeding frequency
Daily
Preferred foods
  • Mature biofilmPrimary natural grazing resource.
  • Complete dwarf-shrimp foodFeed sparingly and remove uneaten food.
  • Leaf litterProvides grazing area and slowly decomposing natural food.

Omnivorous biofilm grazer. Provide mature natural grazing surfaces and small portions of complete shrimp food, leaf litter, algae-based food, and occasional protein-rich food.

Avoid overfeeding. A mature aquarium with continuous biofilm is more important than heavy supplemental feeding.

Breeding

Brood or egg count
Approximately 15–30 eggs, varying with female size and line
Incubation

Maternal care
Baby foods
  • Mature biofilm and fine powdered shrimp foodShrimplets need constant access to microscopic food on established surfaces.

Direct-developing freshwater shrimp. Females carry eggs beneath the abdomen and release miniature shrimplets. Line purity and pattern consistency depend on selecting breeders and preventing unwanted crosses.
