Juveniles are young shrimp — they travel best at this size, and many strains only show their full colour as they mature. After display-ready adults? Contact us.

Pink Steel Shrimp (Caridina) | Single Grade Colony

A pink shrimp with a thick, solid shell — no see-through patches anywhere on it.

Arrives young. Some settle to a soft metallic pink and others to a deeper light red, and the shade keeps moving for the first few moults.

One price, no grades. Sorting them by colour on arrival day would really just be sorting them by age.

Caridina — needs soft, slightly acidic water, so a step up from a first shrimp. Numbers in the FAQ.

Pink Steel is a rare pink-toned mutation isolated from within our Taitibee/Pinto steel lines. Where standard Steels run white, black or blue, this colony reliably throws a stable spectrum from soft metallic pink through to a deeper light red — with the dense, opaque “steel” shell the trait is named for.

About the photo. We ship unsexed juveniles — shell density and final colour saturation are still building at that age. Treat the photo as the target for how their steel armour matures, not the arrival-day look.

“Steel” describes the shell, not just the colour.

  • Solid, not gradient: Unlike a Bolt pattern — strong colour at the head fading to translucent white at the tail — Steel shrimp carry an opaque, ultra-thick shell with colour running solid from head to tail and zero transparency.
  • Shade shifts with growth: Individual juveniles will lean more pink or more red as they grow, moult, and settle into your water — that’s the natural range of the line, not a defect.

We grade by the traits that genuinely vary within a batch — pattern density, colour saturation, how far colour wraps around the shell. Where those differences are visible in the tank from day one, we sort them and price each tier for what it actually is.

Because the pink-to-red shade is still moving as each shrimp grows and moults, sorting on arrival-day colour would just be sorting by age, not quality — the same juvenile can shift its final shade after a few more moults in your tank.

So Pink Steels are one grade, one price — the full pink-to-red spectrum.

10+ of one lineColony starter
Unsexed juveniles at ten all but guarantee both sexes — about 1 in 500 odds of a single-sex group, against 1 in 8 at four — and a group settles faster than a pair. Our 10+ and 20+ prices are built around that. Give them longer than Neocaridina — Caridina breed more slowly on buffering soil and reward stability over tinkering.

Water parameters — Caridina
TDS
100 – 150 ppm
Total dissolved solids — the quickest single number to check. Ours is what they are raised in: match it on arrival, then keep it steady. Swings hurt more than the number itself.
GH
4 – 6 dGH
General hardness — the calcium and magnesium they build shells with. Too little and moults fail; too much and shedding gets hard.
KH
0 – 1 dKH
Carbonate hardness — the buffer that stops pH drifting between water changes.
pH
5.5 – 6.5
Set by your substrate and KH far more than by dosing. Hold it steady inside the band rather than chasing a number.
Temp
20 – 24 °C
Cooler slows moulting and breeding; warmer speeds everything up and shortens lives. Stay inside the band.
Tank
30+ L
The minimum for a settled colony. A bigger tank holds its water steadier, so we recommend larger groups in larger tanks — stability is what keeps shrimp alive.

Buffered RO water on an active substrate — near-zero KH is correct here, not a fault.
