Neocaridina · BeginnerPhoto vs. what ships

The photo shows a high-grade or best-looking adult from the batch. We ship unsexed juveniles, 0.6–1.2 cm — too young to tell male from female. They arrive pale from the trip and colour back up within days.

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.

Description

Ultra Gold Shrimp (Neocaridina) | Single Grade Colony

At a glance

A solid golden-yellow shrimp with a bright stripe down its back.

Arrives young and paler, and the back stripe often is not there yet. Both fill in as they grow.

One price, no grades. The gold and the stripe both come with age, so sorting juveniles would be guesswork.

Neocaridina — the easier of our two shrimp families, hardy and quick to breed, and a good first shrimp. Numbers in the FAQ.

Description

The Yellow Golden Back is a yellow Neocaridina with an opaque stripe running down its back. A standard Golden Back keeps the body a paler yellow so the stripe stands out; our Ultra Gold is bred for a deeper, heavier golden yellow across the whole body as well, so the shrimp reads as solid gold with the stripe on top. Same hardiness and quick breeding as any cherry shrimp.

About the photo. The shrimp pictured is one of the best-looking adults from the batch. Juveniles arrive a lighter yellow and the back stripe may be missing altogether; both fill in with each moult.

Colour & Care

What to expect as they grow:

Colour builds with age: Young Neocaridina are naturally more see-through. The yellow thickens and deepens with each moult, until the body is solid gold at full size.
The stripe comes last: The golden back line is thin or absent on juveniles. It widens and defines itself as the shrimp matures.

Grading

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.

Ultra Golds are not sortable that way, because both the depth of gold and the stripe are tied to age: a paler juvenile without a stripe today is simply younger, not lesser.

So Ultra Golds are one grade, one price — robust unsexed juveniles from the same colony.

0.6–1.2 cmUnsexed juveniles

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. In a fully cycled tank held in their temperature band, fed lightly and left alone, expect the first berried females in around three months.

Water parameters — Neocaridina

TDS

150 – 250 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.

6 – 10 dGH

General hardness — the calcium and magnesium they build shells with. Too little and moults fail; too much and shedding gets hard.

2 – 6 dKH

Carbonate hardness — the buffer that stops pH drifting between water changes.

6.8 – 7.8

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

20+ 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.

Commonly kept 18–28 °C; breeding slows markedly below ~20 °C. Raised in remineralised Melbourne tap water.

FAQ — before you buy 8 quick answers

What actually turns up in the bag?

Unsexed juveniles, 0.6–1.2 cm — about the size of a grain of rice, and too young to tell male from female. Shipping at this size gives the best survival and the easiest adaptation to your water, and you always end up with both sexes. Adults are available on request at roughly twice the juvenile price.

Will they look like the photo?

Not on day one. The photo is a high-grade or best-looking adult from the batch; the shrimp you receive is young and still filling in. The colour packs in with each moult. Every shrimp is an individual, so no two carry exactly the same pattern.

Why is there no grade to choose?

Because nothing on this line is worth sorting at the size we ship — the differences are down to age, or to your tank, not to the shrimp. Every animal in the bag meets one standard, and the Grading panel above says why. Where we do split a line into Entry, Mid, High and Collector, the grade describes appearance only, never health.

Can I keep them in my water?

Almost certainly. Neocaridina live happily in ordinary treated tap water inside the ranges in the water card above, and forgive the mistakes every new keeper makes. Keep it steady rather than perfect: a reading a little outside the range is far better than one that keeps moving. A tank that has been cycled — run for a few weeks until it can process waste — is the one thing that is not optional.

They arrived pale and barely moving. Is that normal?

Yes. Every shrimp arrives pale from the trip and colours back up within hours to a few days — a Green Emerald can take about a week. Float the bag, then drip your tank water into it slowly over an hour or two before releasing them; the change in water should happen gradually. If any animal is dead on arrival, photograph it in the unopened bag and contact us within 8 hours of delivery — the Live Arrival Guarantee covers it.

Live Arrival Guarantee & DOA policy →

How do they travel?

Express post only, bagged with oxygen and insulated, dispatched on Mondays and Tuesdays so no animal sits in a depot over a weekend. Someone needs to be home to receive the parcel on the day — live animals cannot go to a PO box, a parcel locker or a safe-drop. We cannot send live animals to Western Australia, the Northern Territory or Tasmania.

Shipping policy →

How many should I start with?

Ten is the sensible minimum for a colony that breeds: with unsexed juveniles it all but guarantees both sexes, and a group settles faster than a pair. Our volume prices are built around that. Mixing colours of the same genus in one tank is fine to look at, but they will interbreed and the offspring drift back toward wild colouring — one colour per tank if you want to keep the line.

What do I do in the first 24 hours?

Lights off, bag closed. Float the sealed bag in the tank for 10–15 minutes so the temperature matches — darkness lowers stress.

Drip, don’t pour. Drip tank water into the bag slowly. A sudden change in TDS, GH or pH is the number-one cause of losses in the first week.

Something wrong? Photograph and video the unopened bag and email us within 8 hours — the Live Arrival Guarantee covers a replacement or a refund of the livestock value.
