In the world of aquarium shrimp, the two most popular types are Caridina and Neocaridina. Although they may look similar at first glance, they differ in requirements, water parameters, and breeding difficulty level.

If you’re just starting your shrimp-keeping journey, this guide will help you decide which shrimp will be the best choice.

What are Caridina shrimp?

Caridina is a group of shrimp originating mainly from Asia. They are valued for their extraordinary colors, patterns, and high breeding value.

The most popular varieties include:

• Blue Bolt
• Red Galaxy Fishbone
• Red Galaxy Boa
• Crystal Red
• Crystal Black
• Shadow Panda
• King Kong

Caridina shrimp are stunning in appearance, but require more stable water parameters.

What are Neocaridina shrimp?

Neocaridina are more resilient and easier to maintain freshwater shrimp.

The most popular varieties are:

• Red Cherry
• Bloody Mary
• Blue Dream
• Orange Sakura
• Yellow Neon
• Green Jade

They are an ideal choice for those starting their shrimp-keeping journey.

Water parameters – the biggest difference

The most important difference between Caridina and Neocaridina concerns water parameters.

Caridina

• GH: 5–6
• KH: 0–1
• pH: 5.5–6.8
• TDS: 100–140 ppm
• Temperature: 20–23°C

Caridina require soft and slightly acidic water.

Neocaridina

• GH: 6–8
• KH: 2–6
• pH: 6.5–7.8
• TDS: 180–250 ppm
• Temperature: 20–25°C

Neocaridina tolerate a much wider range of parameters.

Different mineralizer for Caridina and Neocaridina

Many beginners make the mistake of using the same mineralizer for all shrimp.

Mineralizer for Caridina

Caridina require GH+ mineralizers.

Such products raise only general hardness (GH) without increasing KH. This allows maintaining low pH and conditions suitable for Taiwan Bee and Galaxy varieties.

Mineralizer for Neocaridina

Neocaridina feel best when using GH/KH+ mineralizers.

They raise both GH and KH, providing a more stable environment and greater resistance to parameter fluctuations.

Substrate – active or neutral?

Caridina

For Caridina, active substrates are recommended, such as:

• ISTA Premium Soil
• ADA Amazonia
• Neo Soil

Active substrates help maintain low pH and KH close to zero.

Neocaridina

Neocaridina can be kept on:

• quartz sand,
• gravel,
• neutral substrates,
• active substrates.

They are much less demanding in this regard.

Breeding

Both types breed in freshwater.

After reaching maturity, females carry eggs under their abdomen for about 3–4 weeks, after which miniature shrimp are born that are exact copies of adult specimens.

Under appropriate conditions, both Caridina and Neocaridina breed very readily.

Which shrimp are easier?

In terms of ease of breeding, Neocaridina are definitely the winner.

They are more resistant to beginner mistakes and better tolerate minor parameter fluctuations.

Caridina require more knowledge, regular parameter measurements, and a stable aquarium.

Which shrimp are more beautiful?

It’s a matter of taste.

Caridina offer the most spectacular patterns and colors available in the world of aquarium shrimp.

Neocaridina, on the other hand, impress with intense, solid colors and ease of breeding.

Summary

If you’re just starting your shrimp-keeping journey, the best choice will be Neocaridina. They are easy to maintain, resilient, and breed quickly.

If you already have experience and want to breed the most impressive varieties, it’s worth considering Caridina, such as Blue Bolt, Galaxy Fishbone, or Galaxy Boa.

Regardless of your choice, the key to success is stable water parameters, appropriate mineralizer, and a biologically mature aquarium.
