Red Ruby Taiwan Bee Shrimp (Caridina cantonensis) – Soft-Water Caridina

Red Ruby Taiwan Bee Shrimp is a deep red ornamental Caridina line for specialist soft-water shrimp aquariums. The trade commonly anchors this line to Caridina cantonensis. Because bee-shrimp taxonomy and captive line history can be complicated, this page keeps the supplier-backed trade identity without claiming a wild locality or genetically verified pure species lineage.

One quantity supplies one unsexed live shrimp. Red Ruby shrimp are peaceful and can form attractive breeding colonies, but they are less forgiving of unstable water than Neocaridina such as Cherry Shrimp. A mature, low-KH aquarium with stable remineralised water, biofilm and gentle shrimp-safe filtration is the foundation of good care.

Red Ruby Taiwan Bee Shrimp at a glance

Water setup: stability comes first

Red Ruby Taiwan Bees do best in soft, mildly acidic water with very low carbonate hardness. Many keepers use reverse-osmosis water remineralised with a shrimp GH product and an active buffering substrate. That approach makes the mineral profile repeatable and avoids trying to force unsuitable hard tap water into the target range.

Keep temperature around 20–25°C, pH roughly 5.5–6.8, GH about 4–6 and KH close to zero. Do not chase readings with sudden corrections. Shrimp are particularly sensitive to abrupt changes in temperature, mineral content and dissolved solids. Small consistent water changes are usually easier on an established colony than large swings.

Ammonia and nitrite should remain at zero. Keep nitrate low through measured feeding, mature filtration and regular maintenance. Avoid copper-based medication and any treatment not confirmed safe for freshwater shrimp.

Aquarium setup

Use a fully cycled, mature aquarium with a sponge filter or a fine intake guard that cannot pull in shrimplets. Moss, leaf litter, wood and textured hardscape create useful grazing area and shelter after moulting. A 20-litre aquarium can support a small group, but 30–45 litres or more is easier to stabilise and gives a growing colony more room.

An active shrimp substrate is commonly used because it supports the low-pH, low-KH approach favoured by Taiwan Bee lines. Keep the layout accessible enough to remove uneaten food and observe the colony without constant rescapes.

Feeding

A mature aquarium should provide continuous biofilm grazing. Supplement it with a quality specialist shrimp pellet or wafer, leaf litter and occasional fine powdered food for a breeding colony. Feed lightly. If prepared food remains for hours, reduce the next portion.

Protein-rich foods can be used occasionally, especially for breeding adults, but heavy feeding quickly damages small soft-water aquariums. The best feeding plan supports moulting and growth without creating a constant organic load.

Tank mates

The safest setup is a shrimp-focused aquarium with peaceful snails. Small fish may leave adults alone yet still consume shrimplets, so a community tank reduces breeding success. If maximum colony growth or preservation of the line matters, keep the shrimp without fish.

Other soft-water Caridina can share similar parameters, but closely related lines may interbreed. Do not mix valuable colour lines if you want predictable offspring. Neocaridina do not usually share the same ideal water chemistry, so combining them often creates an unnecessary compromise.

Breeding

Red Ruby Taiwan Bees reproduce entirely in freshwater. A berried female carries eggs under the abdomen until miniature shrimp hatch. There is no brackish larval stage. Shrimplets need mature biofilm, fine food, stable minerals and a filter intake they cannot enter.

Breeding success depends much more on stability than on pushing temperature or feeding heavily. Keep water changes gentle, avoid repeated disturbance and let moss and leaf litter develop microbial life.

Moulting and health

A healthy shrimp grazes actively, moves normally and completes clean moults. Failed moults, unusual lethargy, repeated deaths after water changes or shrimp trying to leave the water should trigger immediate checks of temperature, ammonia, nitrite, GH, KH and recent chemical exposure.

Leave normal empty moult shells in the aquarium unless they are trapping waste; the colony often grazes them. Remove a dead shrimp promptly and review water quality before assuming an infectious disease.

Red Ruby Taiwan Bee questions

What water does a Red Ruby Taiwan Bee need?

Use soft, mildly acidic water around pH 5.5–6.8, GH 4–6 and KH 0–1, with temperature roughly 20–25°C. Stability is more important than chasing an exact decimal.

Do I need RO water?

RO water is not a biological requirement by itself, but remineralised RO is often the most predictable way to create repeatable low-KH Caridina water. Tap water is only suitable when its chemistry already matches the target and remains stable.

What tank size is recommended?

20 litres is a practical minimum for a small group, while 30–45 litres or more is easier to keep stable and better for a growing colony.

How many should I keep?

They are peaceful social shrimp. Starting with a small group of around 6–10 gives better colony behaviour and breeding potential than keeping a single shrimp.

What do Red Ruby shrimp eat?

They graze biofilm and algae continuously and should receive small amounts of specialist shrimp food, leaf litter and occasional appropriate supplements.

Can they live with fish?

Adults may survive with very small peaceful fish, but shrimplets are likely to be eaten. A shrimp-only aquarium is the best option for breeding and preserving the line.

Can I mix them with other Taiwan Bee shrimp?

The water requirements can overlap, but related Caridina lines may interbreed. Keep lines separate if predictable colour and ancestry matter.

Do they breed in freshwater?

Yes. Females carry eggs until miniature shrimp hatch directly into freshwater; there is no brackish larval stage.

Is copper safe for Red Ruby shrimp?

Avoid copper-based medications unless the exact product is specifically confirmed safe for freshwater shrimp at the intended dose.

Is one quantity one shrimp?

Yes. The current listing supplies one unsexed shrimp per quantity.
