Minimum

Soft-water nano tank

10 gal (≈ 38 L), active substrate

Caridina cf. cantonensis 'bee' shrimp need stable soft, acidic water (pH 5.8–6.8, TDS 100–160, GH 4–6, KH 0–1) on a buffering active substrate, with RO/DI + remineraliser. Not suitable for tap-water tanks.

Photo coming soon

Recommended

Dedicated soft-water aquarium

20 gal (≈ 76 L), planted, active soil

A dedicated bee-shrimp tank with active soil, dense moss/buce planting, gentle sponge filtration, and weekly small water changes with parameter-matched water. Species-only or with otocinclus.

Ideal

Show shrimp tank

20–30 gal, ATO + parameter logging

A dedicated show tank with automatic top-off, parameter logging, and a planned breeding programme. Soft-water bees are some of the most parameter-sensitive shrimp in the hobby.

Life & growth stages

How this animal changes through its life — each stage often has its own care, diet and space needs.

Larva

Most marine invertebrates hatch into microscopic planktonic larvae (such as the zoea of crustaceans or the bipinnaria/veliger of echinoderms and mollusks) that drift and feed in the water column. The larva looks nothing like the adult and undergoes major reorganization.

Photo coming soon

Juvenile

After settling out of the plankton, the juvenile takes on a recognizable miniature of the adult body plan — a tiny shell, a small star, or a translucent shrimp. Crustaceans grow by molting, shedding the exoskeleton to enlarge.

Adult

Adults reach full size and reproductive maturity with the species' mature shell, shape, or coloration. Many continue to molt or grow throughout life, and some show sex differences in size or claw/appendage shape.

Color & pattern variants

Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Black Bee (wild bee shrimp) →

UncommonAdvanced

The wild-type Caridina cantonensis 'bee shrimp': a brown-to-black banded shrimp with thin pale stripes, the ancestral form from which Crystal Red, Crystal Black, and the Taiwan Bee lines were all selectively bred.

Tip: Give it the same pristine, soft, slightly acidic water (pH 5.8-6.8, GH 4-6, low TDS) as the crystal lines; it is hardier than Taiwan Bees but still needs a mature, stable, copper-free tank.

Selectively bred (man-made)

representative

Crystal Red Shrimp (CRS)

CommonIntermediate

The foundational designer bee shrimp: crisp red-and-white banding selectively bred from a red sport of the wild black bee shrimp by Hisayasu Suzuki in 1990s Japan. Graded SS-S-A-B by the amount and opacity of white; higher grades (Hinomaru, Mosura) command premiums.

Tip: Buy mid-grade (S/A) stock first — the thick-white SS/Mosura grades are inbred and noticeably weaker. Hold color and white density with a steady TDS around 100-120 in remineralized RO water.

representative

Crystal Black Shrimp (CBS)

CommonIntermediate

The black-and-white sibling of CRS, carrying the same recessive selective-bred pattern but with black rather than red pigment. Graded on identical SS-to-B white-coverage scales.

Tip: CBS and CRS interbreed freely and you can throw both from the same parents, but mixing other Caridina lines muddies the white — keep the colony pure and cull off-color/clear offspring to maintain grade.

representative

Taiwan Bee (Panda, King Kong, Wine Red, Blue Bolt)

High-grade selectively bred Taiwan Bee forms with solid color patterns; even more demanding and pricier than standard crystals.

representative

Golden Bee

UncommonAdvanced

A solid creamy white/golden bee shrimp with no banding, essentially an all-white Taiwan Bee used as the genetic 'blank' base from which many Taiwan Bee colors are produced.

Tip: Golden Bees are the recessive carrier base for Taiwan Bee projects — keep them to breed into King Kong/Wine Red lines, but treat them with the same advanced, stable, copper-free care as any Taiwan Bee.

representative

Taiwan Bee - Panda →

UncommonAdvanced

A Taiwan Bee line showing a clean black-and-white 'panda' pattern, arising from the recessive Taiwan Bee genes layered onto CBS lineage. Crisper, more defined blocks of color than standard CBS.

Tip: Taiwan Bees are far more parameter-sensitive than CRS/CBS — they need a mature, rock-stable tank at pH ~5.8-6.5 on active soil. Drip-acclimate over 1-2 hours; sudden TDS or pH swings cause failed molts.

representative

Taiwan Bee - King Kong →

RareAdvanced

A near-solid deep-black Taiwan Bee with minimal or no white, the dark counterpart to Wine Red. The intense solid coloration is highly prized and the gene is recessive, so true King Kongs are slow to reproduce in number.

Tip: Solid-color Taiwan Bees are the most demanding bee shrimp — keep them in a dedicated, long-matured tank only, never as a first shrimp. Crossing King Kong x Wine Red yields the sought-after blacks/reds but expect low yields and cull mismarks.

representative

Taiwan Bee - Wine Red →

RareAdvanced

A near-solid, deep wine-red Taiwan Bee with little to no white, the red counterpart of King Kong. The opaque body color (vs. CRS banding) is what defines the grade and makes premium specimens valuable.

Tip: Like all Taiwan Bees it is copper-intolerant and unstable in young tanks — use RO remineralized only with a bee-shrimp GH+ product and verify zero copper in your source water and decor.

representative

Taiwan Bee - Blue Bolt →

UncommonAdvanced

A Taiwan Bee derived from the Shadow Panda / King Kong line showing a gradient blue head fading to white, intensity ranging from pale 'extreme blue bolt' to washed-out. One of the most popular modern bee shrimp.

Tip: Blue intensity is partly diet- and parameter-driven — keep a stable mature tank and feed mineral/biofilm foods; pale tanks of Blue Bolts often deepen in color once water and food are dialed in. Stable low TDS holds the blue best.

Habitat & enclosure

Keep a colony in a planted, well-matured, cycled tank of 5-10 gallons (20-40 L) or more. Target soft, slightly acidic water: temperature 68-76F (20-24C), pH 5.8-6.8, GH 4-6, KH 0-2, TDS roughly 100-150. They thrive on stability and very low waste, so a heavily planted, mature tank with low stocking is ideal. Active buffering aquasoil is typically used to hold the low pH. Keep ammonia and nitrite at zero and nitrate near zero.

Substrate

Active buffering aquasoil is standard to maintain the soft, low pH these shrimp need. Layer in driftwood, botanicals, and moss to grow biofilm and provide cover. The soil's buffering capacity declines over a year or two and eventually needs refreshing.

Equipment & setup

Use a gentle sponge filter (shrimplet-safe), a heater only if needed to avoid heat (they like it cool), and a precise TDS/GH/KH test kit. A reverse-osmosis unit plus a GH-only remineralizer designed for bee shrimp is strongly recommended for consistent soft water. Avoid any copper-containing equipment.

Diet

A biofilm and soft-algae grazer at heart. In a mature tank most of the diet is biofilm and aufwuchs; supplement a few times weekly with quality bee-shrimp foods, mineral/biofilm powders, blanched vegetables, and botanicals like Indian almond leaves. Feed sparingly to keep nitrates low. Females carry 20-30 eggs and release fully formed shrimplets, so stable colonies multiply over time.

Behavior & temperament

Peaceful, social grazers best kept in groups of 10+ for breeding and natural behavior. Non-aggressive and safe with snails and other peaceful shrimp, but they readily hybridize with tiger shrimp and other Caridina cantonensis lines, so keep grades and species separate to preserve color. They are display-only animals and are not handled.

Health

Among the more demanding shrimp: very sensitive to copper, ammonia/nitrite, nitrate buildup, and parameter swings. Most deaths trace to immature tanks, instability, overfeeding, or copper from medications, fertilizers, or plumbing. Never dose copper. Failed molts (white ring) indicate GH/mineral imbalance; bacterial/fungal infection appears as discolored tissue. Drip-acclimate slowly, quarantine new stock, and change water in small, remineralized, parameter-matched amounts.

Tips, DIY & hacks

This is not a starter shrimp; keep Neocaridina or tigers first. Mature the tank for many weeks before stocking and acclimate by long, slow drip. Use RO water remineralized with a bee-shrimp GH product to hit a steady TDS. Keep grades and Caridina species apart to avoid washing out color through crossbreeding.
