Red Line Blue Dot

A selected Red Line: the same red dorsal stripe, plus metallic blue dots along the flanks that catch the light as the shrimp moves.

A great strain isn't one beautiful shrimp — it's the whole colony looking the same.

DISTRIBUTION MAP

An ancient cradle

Sulawesi shrimp are endemic to a handful of ancient tectonic lakes — 1–4 million years old, among the oldest freshwater lakes on earth.

IDENTIFICATION

How to identify a Red Line Blue Dot

🔵Metallic blue dotsSmall blue dots along both flanks that flash metallically as the shrimp grazes.

🔴Red line intactThe Red Line dorsal stripe stays exactly as it is — the blue simply layers over it.

🔍Tightly selectedOnly individuals with clear, even blue dotting are separated into this line.

💡Light it rightModerate light over a dark scape shows the blue best; harsh light washes it out.

The golden rule: stability beats perfect numbers. A swinging parameter does more damage than one that sits slightly off but never moves. Use a Sula Sand substrate and a dedicated bacteria culture to keep the buffer rock-solid.

STRAIN DATA

Strain data

Strain code: RLB-01
Category: Standard / Breeder
Home lake: Towuti
Scientific name: Caridina striata
Adult size: 1.8–2.2cm

Wild species — natural profile

A farm selection out of the wild Lake Towuti Red Line population — still the wild species, not a mutation.

Home lake: Towuti — the largest lake in the Malili system, clear alkaline water that stays stable year round.

Natural habitat: Submerged rocky shoreline, among crevices and sunken roots where biofilm grows thick.

Behaviour: Behaves exactly like Red Line: grazing all day, living in large groups.

Conservation: An extremely narrow natural range under pressure from mining and invasive species. Captive-bred stock takes pressure off the wild population.

Keeping note: Keep the line pure to hold a high rate of blue dotting across generations.

FOOD & SET-UP

The matching set-up

FEEDING

Omnivorous, but mostly grazing on biofilm and algae growing on rock. Add the White Powder + Yellow Powder pair for colour and steady breeding, and set the tank on Sula Sand to hold an alkaline pH long-term.
