Good fit for your tank?

Good fit for

  • A keeper who prefers a natural transparent body with dark tiger stripes over heavily selected solid colours.
  • A cool, clean soft-water aquarium where a traditional tiger colony can breed without the demands of high-grade hybrid lines.
  • A planned Tiger Bee breeding project, provided the pure Wild Type Tiger colony is also maintained separately.

Think carefully if

  • You want to preserve the wild-type line while housing it with bee, Tangerine Tiger, Taiwan-bee, or hybrid Caridina.
  • The aquarium is consistently warm. Wild Tiger shrimp come from cool, oxygen-rich habitats and can struggle during hot summers.
  • You expect a bright solid-colour display. Their appeal is subtle striping and natural variation, which can disappear visually in a busy aquascape.

A slim, mostly clear shrimp with thin dark vertical stripes along the body.

Appearance and Identification

A slim, mostly clear shrimp with thin dark vertical stripes along the body.

Accepted species associated with aquarium-trade tiger shrimp material.

Females are usually slightly larger, with a fuller underside, particularly when carrying eggs. Males are slimmer, although the differences can be subtle.

Jumping risk
Low

Use a mature aquarium of 20 litres or more with plants, wood, and plenty of biofilm. Keep filter intakes guarded so young shrimp are not pulled in, and avoid sudden changes.

Behaviour and Tankmates

Peaceful and active, spending most of the day grazing on biofilm and plants.

Maintain with conspecifics or peaceful shrimp-safe tankmates where ecological requirements overlap.

Not normally territorial.

Best in a species-only tank, or with very small, peaceful fish that will not eat young shrimp. Tiger shrimp can interbreed with bee shrimp, so keep them apart if you want lines to stay true.

Stability importance
Very important

Soft to moderately hard, slightly acidic to neutral water suits these shrimp. Published figures vary, especially for KH, so keep to the lower end if breeding.

Parameter caveat
Stable, mature conditions are essential; do not chase exact numbers through abrupt corrections.

Feeding

Preferred foods
  • Mature biofilmCore natural grazing resource.
  • Fine complete shrimp foodFeed sparingly and remove excess.

Omnivorous grazer and detritivore. Maintain mature biofilm and provide varied small foods without allowing waste to accumulate.

Monitor body condition and avoid overfeeding or unstable organic waste accumulation.

Baby foods
  • Microscopic natural food and mature biofilmExact juvenile or larval requirements depend on the species.

Females carry eggs under the abdomen, and the young hatch as tiny shrimp with no larval stage.
