Intermediate Level

4. Amano Shrimp (Caridina multidentata)

Difficulty: ⭐⭐⭐☆☆ (3/5)

An Amano Shrimp (Caridina multidentata), one of the most popular freshwater shrimp, recognized for its transparent body and exceptional algae-eating abilities.

Made famous by aquascaper Takashi Amano, Amano Shrimp are widely regarded as the best algae-eating shrimp in the aquarium hobby. They consume hair algae, diatoms, and leftover food more aggressively than most dwarf shrimp.

Unlike Cherry Shrimp, however, they will not reproduce in freshwater. Their larvae require brackish water to develop, so most specimens available in stores are wild-caught or commercially bred.

Pros

• Exceptional algae control

• Larger and more robust

• Peaceful community shrimp

• Long lifespan

Cons

• Won’t breed in freshwater

• Can become quite large for very small nano tanks

5. Blue Dream Shrimp (Neocaridina davidi) Difficulty: ⭐⭐⭐☆☆ (3/5)

A Blue Dream Shrimp (Neocaridina davidi) showcasing its deep sapphire-blue coloration, a hardy and eye-catching favorite for planted nano aquariums.

Blue Dream Shrimp are prized for their deep sapphire-blue coloration. Although their care requirements remain easy, maintaining consistently vibrant offspring requires selective breeding over multiple generations.

In healthy planted tanks, their blue coloration contrasts beautifully against lush green carpeting plants.

Ideal for: Hobbyists looking to expand beyond basic shrimp while still enjoying relatively straightforward care.

6. Black Rose Shrimp (Neocaridina davidi)

A Black Rose Shrimp (Neocaridina davidi) displaying its rich, velvety black coloration, adding striking contrast and elegance to planted nano aquariums.

Black Rose Shrimp (Neocaridina davidi) are a selectively bred variety known for their rich, velvety black coloration. Their dark appearance contrasts beautifully against bright green aquatic plants and light-colored hardscape, making them a favorite among aquascapers.

Like other Neocaridina, they’re hardy, peaceful, and easy to breed, making them suitable for beginners who want something more unique than traditional Cherry Shrimp.

Pros

• Deep black coloration

• Hardy and beginner-friendly

• Excellent algae and biofilm grazers

• Breeds readily in freshwater

Advanced Level

7. Crystal Red Shrimp (Caridina cantonensis)

Difficulty: ⭐⭐⭐⭐☆ (4/5)

A Crystal Red Shrimp (Caridina cantonensis) showcasing its vibrant red-and-white pattern, one of the most iconic and sought-after freshwater shrimp for planted nano aquariums.

Crystal Red Shrimp are considered the gateway into advanced shrimp keeping. Their striking red-and-white patterns make them one of the most beautiful dwarf shrimp available, but they demand much greater water stability than Neocaridina species.

Successful keepers typically use:

• RO (Reverse Osmosis) Water

Purified water that has had almost all minerals, chlorine, and other impurities removed. Starting with pure water allows shrimp keepers to control exactly what minerals are added back.

• Remineralized Shrimp Minerals

Because RO water contains almost no minerals, special shrimp mineral products are added back to provide essential calcium, magnesium, and other minerals needed for healthy growth, successful molting, and breeding.

• Active Buffering Substrate

Unlike ordinary aquarium gravel or sand, an active buffering substrate helps maintain a slightly acidic pH, which Crystal Red Shrimp prefer. It also helps keep water parameters stable over time.

• Low TDS (Total Dissolved Solids)

TDS measures the total amount of dissolved minerals in the water. Crystal Red Shrimp thrive in relatively low TDS water—typically between 100 and 140 ppm. Keeping TDS stable is just as important as keeping it within the correct range.

• Stable Temperatures

Crystal Red Shrimp are sensitive to sudden temperature changes. A consistent water temperature between 20–24°C (68–75°F) helps reduce stress and supports healthy molting and breeding.

8. Crystal Black Shrimp (Caridina cantonensis)

Difficulty: ⭐⭐⭐⭐☆ (4/5)

A Crystal Black Shrimp (Caridina cantonensis) displaying its distinctive black-and-white banding, a favourite among experienced shrimp keepers for its elegant appearance and striking contrast.

Crystal Black Shrimp have the same care requirements as Crystal Reds but feature elegant black-and-white markings. Their dramatic coloration complements minimalist aquascapes and high-end nature aquariums.

Many hobbyists eventually keep both Crystal Red and Crystal Black colonies, but they should understand the implications of selective breeding and maintaining desired patterns.

9. Tiger Shrimp (Caridina mariae and related varieties)

Difficulty: ⭐⭐⭐⭐☆ (4/5)

A Black Fancy Tiger Shrimp displaying its distinctive black-and-white fishbone pattern, a highly prized variety among experienced Caridina shrimp keepers.

Tiger Shrimp are recognized by their vertical striping and translucent bodies. They are more sensitive to changing water conditions than Neocaridina and thrive in mature aquariums with stable parameters.

Modern selective breeding has also produced stunning blue and orange tiger varieties that are highly sought after by enthusiasts.

10. Taiwan Bee Shrimp

Difficulty: ⭐⭐⭐⭐☆ (4.5/5)

A Black King Kong Shrimp (Caridina cantonensis), a premium Taiwan Bee variety prized for its bold black-and-white coloration and highly sought after by experienced shrimp keepers.

Taiwan Bee Shrimp include some of the most coveted shrimp in the hobby, such as Blue Bolt, King Kong, Panda, and Wine Red varieties. Their unusual colours and patterns make them premium display creatures.

However, they require:

• RO water

• Precise remineralization

• Active substrate

• Stable TDS

• Careful feeding

• Excellent water quality

These shrimp reward experienced keepers with some of the most spectacular colours available.

11. Sulawesi Cardinal Shrimp (Caridina dennerli)

Difficulty: ⭐⭐⭐⭐⭐ (5/5)

A Sulawesi Cardinal Shrimp (Caridina dennerli) displaying its brilliant ruby-red body and distinctive white spots, one of the most vibrant and sought-after freshwater shrimp for advanced aquarists.

The Sulawesi Cardinal Shrimp is one of the most striking freshwater shrimp in the aquarium hobby. Endemic to the ancient lakes of Sulawesi, Indonesia, this rare species is instantly recognizable by its deep crimson-red body covered in brilliant white spots and long white antennae. Its vibrant coloration and unique appearance make it a prized centrepiece for dedicated shrimp keepers.

Unlike most freshwater shrimp, Sulawesi Cardinal Shrimp thrive in warm, alkaline water and require exceptionally stable conditions to remain healthy. Because of their specialized care requirements, they are recommended for experienced aquarists with mature aquariums designed specifically for Sulawesi species.

They need:

• Warm water (27–30°C / 81–86°F)

• High pH

• Mineral-rich water

• Exceptional stability

• Mature aquariums

Sulawesi Cardinal Shrimp thrive in mature aquariums with abundant biofilm growing on rocks and hardscape. Avoid frequent changes to water chemistry, as stability is far more important than making constant adjustments.

Unlike most popular freshwater shrimp that prefer soft, acidic water, Sulawesi Cardinal Shrimp evolved in the ancient volcanic lakes of Sulawesi, where the water is naturally warm, clear, and alkaline. Their unique habitat is one of the reasons they remain one of the most specialized and rewarding shrimp species to keep.
