103 – Caridina University: Intermediate To Advance Freshwater Shrimp Species Guide

Preview of species to be covered

This guide will focus on intermediate to advanced freshwater shrimp species, providing detailed information on their care, requirements, and compatibility. We’ll be covering:

  • Tiger Shrimp
  • Crystal Red/Taiwan Bee Shrimp
  • Cardinal Shrimp

 

Tiger Shrimp

Description and Varieties

Tiger shrimp (Caridina cantonensis) are known for their striking black and white striped patterns, resembling their namesake. Several varieties exist, including:

  • Black Tiger 
  • Blue Tiger
  • Orange Eye Blue Tiger (OEBT)
  • Red Tiger
  • Wild Type Tiger

Care requirements

  • Water parameters: pH 6.0-7.0, temperature 68-78°F (20-26°C)
  • TDS (Total Dissolved Solids): 90-200 ppm
  • Require soft, slightly acidic water
  • Sensitive to nitrates; regular water changes essential
  • Prefer densely planted tanks with plenty of hiding spots

Compatibility with other shrimp

  • Can be kept with other Caridina species with similar water parameter requirements
  • Not recommended to mix with Neocaridina species due to different water parameter needs
  • Avoid keeping with larger, aggressive shrimp species or fish that may prey on them

Crystal Shrimp/Taiwan Bee Shrimp

Description (CRS and CBS): Crystal Red Shrimp (CRS) and Crystal Black Shrimp (CBS) are popular varieties of Caridina cantonensis. These shrimp are known for their striking coloration and intricate patterns.

Crystal Red Shrimp (CRS)

  • Feature a white base color with red patches or bands
  • Grading system based on the amount and intensity of red coloration (from C grade to SSS+ grade)
  • Higher grades display more solid red coverage and clearer white areas

Crystal Black Shrimp (CBS)

  • Similar pattern to CRS, but with a black coloration instead of red
  • Also graded based on the intensity and coverage of black coloration
  • Higher grades show more solid black areas and clearer white patches

Taiwan Bee Shrimp are selectively bred variants of Crystal shrimp, including:

  • Blue Bolt
  • Wine Red
  • Ruby Red
  • Pinto
  • King Kong

Care requirements/Water parameters

  • pH 5.8-6.8
  • Temperature 68-74°F (20-23°C)
  • TDS: 80-150 ppm
  • GH: 4-6 dGH
  • KH: 0-2 dKH
  • Require soft, acidic water
  • Very sensitive to nitrates; maintain levels below 5 ppm
  • Prefer densely planted tanks with driftwood, leaf litter, and plenty of hiding spots
  • Active buffering substrate is recommended to maintain a stable, acidic pH

 

Cardinal Shrimp (Sulawesi Shrimp)

Description: Cardinal Shrimp (Caridina dennerli), also known as Sulawesi Shrimp, are striking freshwater shrimp native to Lake Matano on Sulawesi Island, Indonesia. They are characterized by:

  • Vibrant red coloration with a white stripe running along the back
  • Small white dots scattered across the body, resembling stars
  • Grow to about 1-1.5 inches (2.5-3.8 cm) in length
  • Relatively larger and more active compared to many other Caridina species

Unique care requirements

  • Water parameters: pH 7.5-8.5, temperature 78-86°F (26-30°C)
  • GH: 8-12 dGH
  • KH: 4-8 dKH
  • TDS: 100-200 ppm
  • Require hard, alkaline water unlike many other Caridina species
  • Sensitive to nitrates; maintain levels below 10 ppm
  • Prefer well-oxygenated water with moderate flow
  • Thrive in tanks with rocky landscapes, mimicking their natural habitat
  • Benefit from the addition of crushed coral or limestone to maintain water hardness
  • Regular, small water changes (10-15% weekly) using properly prepared water
  • A diet should include high-quality shrimp foods, blanched vegetables, and biofilm

Conservation status

  • Classified as Endangered by the IUCN Red List
  • Native habitat (Lake Matano) is under threat from pollution and introduced species
  • Wild populations have declined significantly in recent years
  • Captive breeding efforts are crucial for the species’ survival
  • Hobbyists are encouraged to purchase only captive-bred specimens
  • Ongoing research and conservation efforts focus on protecting their natural habitat
  • Responsible keeping and breeding in aquariums can contribute to conservation efforts

I'm Stephanie, and I'm all about creating chill, low-maintenance underwater worlds. My aquascaping journey kicked off in college when I realized I could turn my fish tank into a mini slice of nature. I'm a huge fan of the Walstad method and basically anything that lets me be a bit lazy with my tanks while still keeping them looking awesome. Why fight nature when you can let it do its thing? Lately, I've been obsessed with figuring out how to make Caridina shrimp keeping less of a headache. Everyone's always going on about how finicky these little guys are, but I'm determined to prove that you can keep them happy without turning your life into a never-ending water change.
