Caridina shrimp are some of the most beautiful and delicate freshwater shrimp species available in the aquarium hobby. Known for their vibrant colors, intricate patterns, and unique care requirements, these shrimp are a favorite among enthusiasts. However, keeping Caridina shrimp can be challenging due to their need for precise water conditions.

Fact: Caridina shrimp require soft, acidic water with a stable pH between 5.5 and 6.5. Fluctuations in water parameters can lead to stress, failed molting, and even death.

In this guide, we’ll cover everything from tank setup to breeding and maintenance, helping you create the perfect environment for your Caridina shrimp.

When I first started keeping Caridina shrimp, I made every mistake possible. I was drawn to their stunning colors, especially the deep blues of the Blue Bolt shrimp, but I didn’t realize how sensitive they were to water changes. My first attempt ended in disaster—half of my shrimp died within the first month because I wasn’t maintaining stable water parameters.

Determined to get it right, I researched everything I could about Caridina shrimp. I invested in an RO/DI water system, tested my water religiously, and set up a planted tank with the right substrate. The first time I saw my shrimp successfully molt and breed, I knew I had finally cracked the code.

Now, my Caridina shrimp colony is thriving, and I want to share everything I’ve learned to help you avoid the same beginner mistakes I made.

What Are Caridina Shrimp?

Caridina shrimp belong to the Caridina genus, a group of freshwater shrimp found in Southeast Asia. Unlike the hardier Neocaridina shrimp, Caridina shrimp require low pH and soft water conditions to thrive. They are available in a variety of colors and patterns, with many bred specifically for aesthetic preferences in aquariums. Colors like blue, black and red are among the many options available to enthusiasts.

Fact: The Caridina genus includes over 290 species, but only a handful are commonly kept in aquariums. Selective breeding has resulted in stunning varieties such as Crystal Red Shrimp and Blue Bolt Shrimp.

These shrimp play an essential role in the ecosystem by consuming biofilm, algae, and organic debris, helping to maintain water quality.

Ideal Tank Setup for Caridina Shrimp

Creating the right environment is crucial for Caridina shrimp. Here’s what you need:

Tank Size and Requirements

• Minimum Tank Size: 10 gallons (larger is better for stability).
• Shrimp Population: 5–10 shrimp per gallon, but avoid overcrowding.
• Tank Cover/Lid: Prevents shrimp from escaping.

Substrate and Decorations

Caridina shrimp thrive in soft, nutrient-rich substrate that maintains the correct water chemistry. Recommended substrates include:

• ADA Amazonia
• Controsoil
• Brightwell Shrimp Soil

Adding driftwood, Indian almond leaves, cholla wood, and mosses like Java Moss helps create a natural, stress-free environment.

Water Parameters and Maintenance

Caridina shrimp require stable water conditions:

• Temperature: 68–74°F (20–23°C)
• pH: 5.5–6.5
• GH (General Hardness): 4–6 dGH
• KH (Carbonate Hardness): 0–2 dKH
• TDS (Total Dissolved Solids): 100–150 ppm

Fact: Caridina shrimp cannot tolerate high KH levels. A KH above 2 can cause pH fluctuations, leading to molting problems and fatalities.

Caridina Shrimp Food and Diet

Caridina shrimp are omnivores that thrive on biofilm, algae, and detritus. Provide a balanced diet with powdered shrimp food, blanched vegetables, and microorganism-rich options like Bacter AE and Shrimp King Bio Tase Active.

For natural feeding, addIndian almond leaves, mulberry leaves, and guava leaves, which promote biofilm growth and release beneficial tannins. Avoid over-cleaning the tank, as shrimp graze on algae, and remove uneaten food to maintain water quality.

Best Moss for Caridina Shrimp

• Java Moss – Easy to maintain, excellent for breeding tanks
• Christmas Moss – Dense structure, great for shrimp to hide and graze
• Weeping Moss – Aesthetic cascading growth, promotes natural foraging

5. Can Caridina shrimp live with Neocaridina shrimp?

It is not recommended due to their different water parameter requirements.
