Black Shrimp: The Complete Care Guide

Last updated: July 2026 | 9 min read

Jet black shrimp are some of the most dramatic animals you can put in a planted tank. A deep, opaque black shrimp grazing across pale sand looks almost unreal, and it is no surprise that black morphs have become some of the most requested shrimp in the hobby.

Here is the catch: "black shrimp" is not one animal. The name covers at least three very different shrimp with very different care requirements. Two of them (Black Rose and Black Diamond) are hardy Neocaridina that a first-time keeper can succeed with. The others (Black King Kong and Black Tiger) are Caridina that need soft, carefully managed water and some experience. Buy the wrong one for your water and you will lose shrimp fast, so sorting out which black shrimp you are looking at is the first job of this guide.

Quick Answer

Black Rose and Black Diamond shrimp are hardy black Neocaridina that thrive in the same easy conditions as cherry shrimp: 65 to 78°F, pH 6.5 to 7.5, GH 6 to 10, TDS 150 to 300 ppm. Black King Kong and Black Tiger shrimp are Caridina that need soft, low-KH water (pH 5.5 to 6.5 for Black King Kong) at 68 to 74°F, usually built on RO water and active soil. Beginners should start with Black Rose. Always confirm which species you are buying before you set up the tank.

Black Aquarium Shrimp at a Glance

The Two Families of Black Shrimp

Every popular black dwarf shrimp belongs to one of two genera, and the genus tells you almost everything about care.

Neocaridina black morphs (Black Rose, Black Diamond) descend from the same species as cherry shrimp. They tolerate a wide band of parameters, live happily in dechlorinated tap water in most areas, and breed readily.

Caridina black morphs (Black King Kong, Black Tiger) come from the bee shrimp and tiger shrimp lines. They evolved in soft, mineral-poor streams and need low TDS, low KH, and cooler, rock-stable temperatures. Most keepers run them on RO water with a shrimp-specific remineralizer over active buffering soil.

The two genera look similar at a glance but cannot be kept in identical water at the extremes, and they never interbreed. If you are new to the split, our Caridina vs Neocaridina guide covers it in depth.

Black Rose and Black Diamond Shrimp (The Easy Ones)

Black Rose shrimp are the black color morph of Neocaridina davidi, developed by selectively breeding chocolate and dark brown lines until the color deepened to black. "Black Diamond" is mostly a grading and marketing name applied to the deepest, most opaque black Neocaridina, sometimes with a glossier shell. Different sellers use the two names loosely, and you may also see "Black Onyx" or "Black Cherry." Functionally they are all the same hardy animal.

◆Appearance and Grading

High-grade Black Rose shrimp are solid, opaque black from rostrum to tail. Lower grades show translucent patches on the legs and underside or a rusty brown undertone, especially under bright light. Females are larger, rounder, and usually darker than males, which is true across almost all Neocaridina morphs.

◆Water Parameters

Care is identical to any other Neocaridina:

• •Temperature: 65 to 78°F, with 72 to 76°F as the sweet spot for activity and breeding
• •pH: 6.5 to 7.5 (they tolerate somewhat higher)
• •GH: 6 to 10 dGH so they have the minerals for clean molts
• •KH: 2 to 6 dKH
• •TDS: 150 to 300 ppm

Stability matters more than any single number. A fully cycled tank is non-negotiable, so if you are starting fresh, work through our cycling guide first, and keep the core water parameters steady after that. Mineral-poor water leads to failed molts, which is the most common way keepers lose otherwise healthy shrimp (our molting guide explains the warning signs).

◆Tank Setup

A cycled, planted 5 to 10 gallon tank with a sponge filter is all a Black Rose colony needs. Inert sand or gravel works fine because these shrimp do not need the pH-lowering effect of active soil.

Black King Kong Shrimp (The Advanced One)

Black King Kong (BKK) shrimp are Taiwan bee Caridina, part of the same family tree as crystal red shrimp. Where a Black Rose is matte black, a healthy BKK looks like wet paint: a thick, glossy, almost enamel-like black, usually broken by clean white banding. The "panda" pattern (black with white bands) is the classic look, while "extreme BKK" grades are nearly solid black.

That beauty comes with strict requirements:

• •Temperature: 68 to 74°F, ideally around 70 to 72°F
• •pH: 5.5 to 6.5, held there by active buffering substrate
• •GH: 4 to 6 dGH, KH: 0 to 1 dKH
• •TDS: 100 to 140 ppm
• •Water source: RO or another near-zero TDS source, remineralized with a Caridina-specific GH+ product (an RO remineralizer that adds GH without KH)

BKK are also less forgiving of ammonia spikes, warm spells, and casual water changes than their bee shrimp cousins, and they breed slowly. Most experienced keepers recommend running a crystal red or crystal black colony successfully for six months to a year before attempting Taiwan bees. They cost several times what a Black Rose does, so mistakes are expensive.

Black Tiger Shrimp (The Middle Ground)

Black Tiger shrimp, usually sold as Orange Eye Black Tigers (OEBT), are Caridina mariae, a different species from the bee shrimp line. They are a deep blue-black with striking bright orange eyes, and those eyes are the fastest ID feature in a store tank.

Tigers sit between the two extremes in difficulty. They still want soft, low-TDS water and cool temperatures (68 to 74°F), but they tolerate pH closer to neutral (roughly 6.5 to 7.2) better than bee shrimp do, and they are generally hardier once settled. They remain a soft-water RO project, just a more forgiving one.

How to Tell a Black Neo from a Black Caridina

Store labels are unreliable, and a stressed, washed-out shrimp in a bare dealer tank is hard to judge. Use these checks:

1. •Eyes. Bright orange eyes mean tiger shrimp (Caridina). Black eyes could be anything.
2. •Finish. BKK black looks thick, glossy, and layered, often with crisp white bands. Neocaridina black is flatter and more matte, and lower grades show rusty brown tones or clear patches.
3. •Price. A black shrimp priced like a cherry shrimp is almost certainly a Neocaridina. Taiwan bees cost several times more.
4. •Ask about the water. A good seller can tell you the pH, GH, and TDS the colony was bred in. If they cannot, assume nothing and buy elsewhere.
5. •Body shape is not reliable. The genera differ in subtle ways (rostrum length, size at maturity), but morph-level ID by body shape alone is guesswork for most keepers.

When in doubt, buy from a breeder who names the species, not just the color.

Breeding True and Dealing With Culls

Black is not a naturally stable color in Neocaridina. Left alone, a Black Rose colony drifts back toward its chocolate and wild brown ancestry within a few generations. Keeping a line black takes light ongoing selection:

• •Remove (cull) off-color offspring. Brown, rusty, or heavily translucent juveniles go to a separate tank, a friend, or a community tank as cleanup crew. Culls are healthy shrimp, just off-color.
• •Never mix Neocaridina colors. Black Rose kept with cherry, blue, or yellow Neos will interbreed, and the mixed offspring trend brown. The same reversion pressure applies to lines like blue dream shrimp.
• •Refresh bloodlines occasionally. Adding a few unrelated high-grade blacks every year or two keeps the colony vigorous.

Caridina lines behave differently. BKK from mixed Taiwan bee stock can throw red king kongs, pandas, and other patterns, which many keepers consider a feature rather than a problem.

Why Black Shrimp Show Best on Light Substrate

Substrate choice changes how black shrimp read in the tank more than it does for any other color:

• •Contrast is everything. On dark aquasoil, a black shrimp all but disappears. On pale sand or light gravel, the same shrimp looks ink-black and impossible to miss. This is why breeders photograph black shrimp on white dishes.
• •The color-adaptation caveat. Dwarf shrimp adjust their pigment to their surroundings over time, and low-grade blacks can wash out somewhat over very pale substrate. High-grade, opaque stock holds its color far better, which is one more reason grade matters.
• •The Caridina compromise. BKK and tigers usually need dark active soil for buffering, so you cannot simply switch to white sand. Get contrast instead from pale hardscape (light seiryu-style stone, sand foreground patches) and bright green carpeting plants.

For easy Neocaridina blacks on inert substrate, a light natural sand with green plants is the single best way to show them off.

The Bottom Line

"Black shrimp" spans everything from one of the easiest shrimp in the hobby to one of the hardest. Black Rose and Black Diamond Neocaridina give you the jet black look with cherry shrimp ease: stable, cycled tap water, GH 6 to 10, temperatures in the low 70s, and they will breed on their own. Black King Kong and Black Tiger Caridina deliver a deeper, glossier black but demand RO water, active soil, and cool, stable conditions. Match the shrimp to your water and your experience, put them over a light substrate where you can, and black shrimp will be the most striking thing in the room.

Frequently Asked Questions

◆Are black shrimp hard to keep?

It depends entirely on which black shrimp. Black Rose and Black Diamond are Neocaridina and are as easy as cherry shrimp. Black King Kong and Black Tiger are Caridina that need soft, low-KH, RO-based water and stable cool temperatures, which makes them intermediate to advanced projects.

◆Can Black Rose shrimp live with cherry shrimp?

They can share a tank peacefully, but they will interbreed because both are Neocaridina davidi. The mixed offspring revert toward wild brown over a few generations, so keep colors in separate tanks if you want to preserve them.

◆Why are my black shrimp turning brown?

Usually genetics. Black Neocaridina lines drift back toward their brown ancestry unless off-color offspring are removed each generation. Stress, poor water quality, and very pale substrate can also temporarily wash out color, but a brown juvenile from black parents is simply a low-grade throwback.

◆How much do black shrimp cost?

Black Rose Neocaridina typically sell in the same range as cherry shrimp, a few dollars per shrimp for standard grades. Black King Kong Caridina cost several times more per shrimp, which is another reason to build experience on easier species first.
