Caridina or Neocaridina: what are the differences and which one to choose?

by Jaz Ni September 9, 2026

When you want to start a shrimp aquarium, one question comes up very often: should you choose Caridina or Neocaridina?

These two groups include some of the most popular aquarium shrimp, but their needs can be very different.

Water quality, GH, KH, conductivity, pH, soil type, maintenance difficulty, reproduction and coloration: choosing the right shrimp from the start helps avoid many mistakes.

In this Shrimpsfood guide, we will simply compare Caridina and Neocaridina to help you choose the shrimp best suited to your aquarium and your level.

🦐 Key takeaway: Neocaridina are generally more tolerant and often make an excellent choice for beginners. Many selectively bred Caridina require softer water and more closely monitored parameters.

🦐 What is the difference between Caridina and Neocaridina?

Caridina and Neocaridina correspond to two different genera of freshwater shrimp.

In the world of aquaristics, the term Neocaridina very often refers to the various varieties derived from Neocaridina davidi.

These include in particular:

Red Cherry;
Bloody Mary;
Blue Dream;
Blue Velvet;
Yellow;
Orange Sakura;
Green Jade;
Chocolate;
and many other selections.

As for Caridina, hobbyists notably maintain different lineages of:

Crystal Red;
Crystal Black;
Taiwan Bee;
Red Wine;
Blue Bolt;
King Kong;
Panda;
Tiger;
and many selections resulting from different crosses.

Be careful, however: not all Caridina have exactly the same needs. Tiger shrimp, for example, can be kept in different conditions than certain Taiwan Bee.

📊 Caridina or Neocaridina: quick comparison

Criterion	Neocaridina	Selectively bred Caridina
Difficulty	Fairly accessible	Often more demanding
Water type	Soft to moderately mineralized	Often soft and low-mineral
KH	Often present	Often very low for Crystal/Taiwan Bee
Active substrate	Not essential	Very often used
RO water	Not always necessary	Very commonly used
Tolerance to variation	Generally better	Often lower
For beginners	⭐⭐⭐⭐⭐	⭐⭐⭐

These differences are general: the exact strain and the parameters used by the breeder remain very important.

🔴 Neocaridina: the ideal shrimp for beginners?

For a first shrimp aquarium, the Neocaridina is often the simplest choice.

It has several advantages:

good adaptability;
many colors available;
relatively accessible reproduction;
not necessarily a need for active substrate;
maintenance possible in many properly adapted waters;
colony can develop rapidly under good conditions.

But "easy" does not mean indestructible.

Neocaridina remain sensitive to:

nitrites;
chemicals;
large parameter fluctuations;
excessive temperatures;
poor acclimatization.

🔵 Caridina: why are they more demanding?

Many selectively bred Caridina, especially Crystal and Taiwan Bee, are kept in softer water than Neocaridina.

Breeders frequently use:

RO (Reverse Osmosis) water;
adapted remineralizing salts;
active substrate;
a KH near zero;
controlled conductivity.

This method allows for better control of water parameters.

In return, these shrimp can be less tolerant of mistakes and major fluctuations.

💧 Which GH for Caridina and Neocaridina?

The GH corresponds to the general hardness of the water and specifically reflects the presence of calcium and magnesium.

As a guideline, maintenance is often found around:

Neocaridina: GH around 6 to 10;
Caridina Crystal / Taiwan Bee: GH around 4 to 6.

These values are not absolute rules.

The strain, original breeding parameters, and above all stability remain essential.

📖 Complete guide: Shrimp aquarium GH and KH: what values for Caridina and Neocaridina?

🧪 What is the difference in KH?

It is often regarding KH that the difference between the two types of maintenance becomes particularly visible.

Neocaridina are frequently kept with a measurable KH.

Conversely, many Caridina Crystal and Taiwan Bee are kept with a very low KH, often near zero.

Active substrate generally helps to create and maintain an environment better suited to this type of shrimp.

Therefore, you should not choose your water based on pH alone.

⚡ Which conductivity for Caridina and Neocaridina?

Conductivity is particularly practical for monitoring water mineralization.

The values encountered are generally lower for Caridina kept in soft water than for Neocaridina.

As a guideline:

Neocaridina: often around 250 to 450 µS/cm;
Caridina Crystal / Taiwan Bee: often around 100 to 200 µS/cm;
certain Tiger: around 150 to 250 µS/cm depending on the strain and breeding method.

These ranges are for reference only.

A shrimp raised for several generations in a particular water may be accustomed to slightly different parameters.

🌱 Which substrate to choose for Neocaridina?

Neocaridina generally do not need active substrate to be kept properly.

You can use, for example:

a neutral substrate;
sand adapted to the aquarium;
inert gravel.

The advantage of a neutral substrate is that it has little influence on water parameters.

It therefore becomes possible to adapt the composition of the water itself.

🌿 Which substrate to choose for Caridina?

For Caridina of the Crystal or Taiwan Bee type, active substrate is very often used.

Its role is notably to help maintain conditions adapted to soft, lightly buffered water.

It can influence:

pH;
KH;
overall parameter stability.

The choice of substrate should therefore be considered when preparing the aquarium.

⚠️ Warning: active substrate does not replace properly prepared water. You must consider the whole: water, salts, GH, KH, conductivity, and substrate.

🚰 Tap water or RO water?

For Neocaridina

Tap water may be suitable if its parameters are adapted and it does not present any particular problems for the shrimp.

But the composition of tap water varies greatly by region.

You must therefore test it before deciding to use it.

For Caridina

For many sensitive Caridina, the use of remineralized RO water is widespread.

It allows you to start with very low-mineral water and then add exactly the salts necessary to reach the desired GH and conductivity.

🌡️ What temperature for Caridina and Neocaridina?

Both groups generally appreciate moderate temperatures.

In many shrimp aquariums, a temperature around 20 to 23°C is well-suited.

But once again, the exact species must be taken into account.

Excessive heat is particularly problematic because it:

speeds up metabolism;
decreases the amount of dissolved oxygen;
can increase stress;
can weaken sensitive colonies.

🍽️ Do Caridina and Neocaridina eat the same thing?

Their diet is globally similar.

Both Caridina and Neocaridina spend a large part of their time looking for:

biofilm;
micro-organisms;
plant matter;
organic particles present on surfaces.

In an aquarium, a varied diet can supplement these natural resources.

You can alternate:

vegetable foods;
protein-rich recipes at an appropriate frequency;
leaves;
specialized pellets;
foods intended for juveniles.

👶 Which shrimp reproduces most easily?

The Neocaridina is generally easier to breed in an adapted aquarium.

When conditions are good:

the female develops eggs;
she molts;
mating can occur;
the eggs are then carried under the abdomen;
the young are born in the form of small, already formed shrimp.

Caridina Crystal and Taiwan Bee can also reproduce very well when their needs are met.

They simply become more demanding regarding water quality and stability.

🦐 What role does molting play in reproduction?

Molting is directly linked to the shrimp's reproductive cycle.

After certain molts of a mature female, males can become particularly active throughout the aquarium.

This is often a sign that a female is ready to mate.

Poor molting conditions can therefore also have an impact on the development of a colony.

🎨 Caridina or Neocaridina: which are the most colorful?

There is no real winner.

Both groups now have many spectacular selections.

In Neocaridina

There are notably colors such as:

red;
blue;
yellow;
orange;
green;
brown;
black.

In Caridina

The patterns can be extremely complex:

red and white;
black and white;
blue;
deep red;
Tiger patterns;
metallic or highly contrasted selections.

For enthusiasts of genetic selection, the possibilities are therefore very significant in both groups.

🧬 Can you mix several colors of Neocaridina?

Yes, they can live together if their needs are identical.

But you should know that the different colors of Neocaridina are generally derived from selective breeding of the same species or very closely related lineages.

They can therefore interbreed.

Over the generations, mixing colors can lead to the appearance of individuals that are less intensely colored and sometimes similar to wild forms.

If your goal is to maintain a stable color, it is preferable to keep only one lineage per aquarium.

🧬 Can different Caridina be mixed?

That depends on the Caridina involved.

Many Crystal and Taiwan Bee lineages can crossbreed with each other.

For breeders working on selection, the choice of crosses is therefore particularly important.

Before mixing several lineages, find out about their genetic origin and your objective:

maintain a pure strain;
obtain certain patterns;
carry out selective breeding;
or simply create a decorative colony.

❓ Can Caridina and Neocaridina live together?

Technically, some can coexist if the chosen parameters fall within a range acceptable to both.

But this is not always the best solution.

The ideal needs of a Neocaridina and a Caridina Taiwan Bee, for example, are not identical.

You risk looking for a compromise rather than offering optimal conditions for each species.

💡 For serious breeding: keeping each strain in an aquarium adapted to its needs facilitates parameter stability and selection.

🧬 Can Caridina and Neocaridina reproduce together?

No.

Caridina and Neocaridina belong to different genera and do not crossbreed under standard aquarium conditions.

You can therefore keep a Caridina and a Neocaridina in the same tank without creating hybrids between these two genera.

The main problem with their coexistence is related more to water parameters than to reproduction.

🚚 Is the acclimation different?

Regardless of the shrimp chosen, it is important to compare the transport water with that of your aquarium.

The difference can be significant, particularly for:

conductivity;
GH;
KH;
pH;
temperature.

A gradual drip acclimation is particularly beneficial to limit a sudden transition.

🦐 The Shrimpsfood advice

Don't choose your shrimp solely for their color.

Start by testing the water you have available, and then decide whether you want to adapt the shrimp to your setup or build the setup around the chosen strain.

It is often this decision, made before the purchase, that makes the difference between an aquarium that is difficult to stabilize and a colony that develops sustainably.
