Types Of Pet Shrimp – The Ultimate Guide To Choosing Your Tiny Aquatic Pets

If you have ever watched a colony of shrimp busily grazing on algae, you know how incredibly relaxing and rewarding this hobby can be. Many aquarists agree that adding these tiny, colorful invertebrates is the best way to bring a “nano” world to life.

In this guide, I promise to break down the most popular types of pet shrimp so you can choose the perfect species for your water parameters and experience level. We will preview everything from the hardy beginners’ favorites to the more challenging, high-end varieties that seasoned pros adore.

Whether you want a vibrant pop of red or a professional-grade algae eater, there is a shrimp out there waiting for you. Let’s dive into the fascinating world of freshwater and brackish shrimp to find your next aquatic companion.

Neocaridina davidi: The Perfect Starting Point

When people first start looking into the various types of pet shrimp, they almost always encounter the Neocaridina davidi species. These are widely considered the “gateway” shrimp because they are exceptionally hardy and can adapt to a wide range of water conditions.

Unlike more sensitive species, Neocaridina can thrive in standard tap water (once dechlorinated) and are very forgiving of minor beginner mistakes. They are also prolific breeders, meaning you can start with a small group and soon have a bustling colony.

The Iconic Cherry Shrimp

The most famous member of this group is the Red Cherry Shrimp. These little guys have been selectively bred for decades to achieve deep, solid red colors that look stunning against green aquatic plants.

If red isn’t your favorite color, don’t worry! You can find Neocaridina in almost every color of the rainbow, including “Blue Dream,” “Yellow Golden Back,” “Orange Sakura,” and even dark “Chocolate” varieties.

Caring for Your First Colony

Maintaining these shrimp is straightforward, but you should still prioritize stability. They love grazing on biofilm and algae, so a mature tank with some driftwood and moss is ideal.

I always recommend using a sponge filter for Neocaridina tanks. This prevents the tiny shrimplets from being sucked into the intake and provides a massive surface area for beneficial bacteria to grow.

Caridina cantonensis: The Collector’s Choice

Once you have mastered the basics, you might find yourself drawn to the more intricate patterns of Caridina cantonensis. This group includes some of the most beautiful and sought-after types of pet shrimp in the world, such as Crystal Reds and Bee Shrimp.

However, these shrimp are significantly more sensitive than their Neocaridina cousins. They require specific water parameters and are less tolerant of fluctuations in temperature or chemistry.

Crystal Red and Bee Shrimp Varieties

Crystal Red Shrimp (CRS) are famous for their striking red and white bands. They are graded based on the intensity and coverage of their white coloration, with higher grades often fetching significant prices.

Beyond the classic CRS, you will find bee shrimp types like the Black Bee, Blue Bolt, and the stunningly complex “Taiwan Bees.” These shrimp offer a level of visual detail that is truly unmatched in the nano aquarium world.

The Need for Soft Water and Active Substrate

To keep Caridina shrimp successfully, you generally need to use RO (Reverse Osmosis) water remineralized to specific levels. They prefer “soft” water with a very low Carbonate Hardness (KH).

Most experts use an active substrate for these tanks. This special soil helps buffer the pH to a lower, slightly acidic level (around 6.0 to 6.8), which mimics their natural habitat and keeps them healthy.

Utility and Cleanup Specialists

Not every shrimp is kept just for its looks; some are prized for the “work” they do in the aquarium. If you are struggling with algae or leftovers, these specialized types of pet shrimp are your best allies.

Adding these to your tank is like hiring a tiny, 24/7 janitorial crew. They are often more active and larger than the colorful dwarf varieties, making them great additions to community tanks with peaceful fish.

The Legendary Amano Shrimp

The Caridina multidentata, or Amano Shrimp, is the undisputed king of algae eating. Named after the famous aquascaper Takashi Amano, these shrimp are larger and much more robust than Cherry shrimp.

They are famous for eating hair algae and other nuisance varieties that most fish won’t touch. While they don’t breed easily in freshwater, their long lifespan and work ethic make them a staple in a dedicated shrimp setup.

Ghost Shrimp: The Transparent Scavengers

Ghost shrimp are often sold as “feeder” shrimp, but they make fascinating pets in their own right. Their transparent bodies allow you to actually see their internal organs and the food they have recently eaten.

They are excellent scavengers and will quickly clean up any uneaten fish food. Just be sure you are buying true Ghost shrimp, as some look-alikes can be slightly more aggressive toward small fish or other shrimp.

Giants of the Shrimp World: Filter Feeders

If you want something truly unique, you might consider filter-feeding shrimp. These types of pet shrimp do not “graze” on surfaces like other species; instead, they have specialized fan-like appendages to catch particles from the water.

Because of their feeding method, they require a tank with a decent current. You will often see them perched on a piece of wood or a rock directly in front of the filter outlet, “fanning” for their dinner.

Bamboo Shrimp and Vampire Shrimp

The Bamboo Shrimp is a beautiful, woody-brown shrimp that can grow up to 3 inches long. They are peaceful giants that spend their days filtering the water for microscopic organisms and crushed flakes.

Even more impressive is the Vampire Shrimp. Despite the scary name, they are incredibly shy and peaceful. They have a stunning blue or grey coloration and can live for several years if their dietary needs are met.

Essential Water Parameters for Different Types of Pet Shrimp

Understanding water chemistry is the secret to long-term success. Below is a quick-reference table to help you match your water to the right shrimp species.

Shrimp Type	Common Name	Ideal pH	TDS Range	Difficulty
Neocaridina davidi	Cherry Shrimp	6.5 – 8.0	150 – 300	Easy
Caridina cantonensis	Crystal Red / Bee	6.0 – 6.8	100 – 150	Intermediate
Caridina multidentata	Amano Shrimp	6.5 – 7.5	150 – 250	Easy
Atyopsis moluccensis	Bamboo Shrimp	6.5 – 7.5	150 – 250	Moderate
Halocaridina rubra	Opae Ula	8.0 – 8.4	N/A (Brackish)	Very Easy

Monitoring your Total Dissolved Solids (TDS) is especially important for Caridina species. If the TDS gets too high or too low, it can lead to molting issues, which is a common cause of death for aquarium shrimp.

Setting Up Your Tank for Success

Before you bring home any types of pet shrimp, you need to ensure their environment is ready. A common mistake is adding shrimp to a “sterile” or brand-new tank. Shrimp need a mature ecosystem to thrive.

Focus on creating a “bio-mature” environment. This means the tank has been cycled and has had time to grow a healthy layer of biofilm on the surfaces of rocks, plants, and glass.

The Importance of Live Plants

Live plants are not just for aesthetics; they are functional tools for shrimp health. Plants like Java Moss, Subwassertang, and floating varieties provide hiding spots for molting shrimp and surfaces for food to grow.

Shrimp feel much more secure when they have cover. A heavily planted tank will encourage your shrimp to spend more time out in the open, as they know they can quickly retreat to safety if they feel threatened.

Substrate and Filtration Choices

As mentioned earlier, your choice of substrate depends on the species. For maintaining cherry shrimp, an inert sand or gravel works perfectly. For Bee shrimp, you will need that pH-lowering active soil.

Regardless of the species, always aim for a gentle filter. A high-flow powerhead might be great for Bamboo shrimp, but for most dwarf varieties, a simple air-powered sponge filter is the gold standard for safety and oxygenation.

Common Health Issues and Prevention

Even the most experienced aquarists occasionally face health hurdles. One common issue is Scutariella japonica, a small parasite that looks like tiny white hairs on the shrimp’s head.

Fortunately, this is usually easy to treat with a quick salt dip or by removing molted shells where the parasites lay eggs. Keeping your water clean and avoiding overfeeding is the best way to prevent most diseases.

Always quarantine new arrivals if you have an established colony. It is much easier to treat five new shrimp in a small container than to treat a hundred shrimp in a 20-gallon planted tank!

Frequently Asked Questions (FAQ)

Can I mix different colors of Cherry shrimp together?

Yes, you can, but be aware that they will interbreed. Over time, the colorful traits will fade, and the offspring will eventually revert to their natural “wild” brown or clear coloration.

Do I need a heater for my shrimp tank?

Most types of pet shrimp prefer cooler temperatures between 68°F and 74°F. In many homes, a heater isn’t strictly necessary unless your room temperature drops significantly at night.

How many shrimp can I keep per gallon?

Shrimp have a very low bio-load. A common rule of thumb is 5 to 10 dwarf shrimp per gallon, though a well-planted and filtered tank can often support more as the colony grows.

What should I feed my pet shrimp?

While they eat biofilm and algae, you should supplement their diet with specialized shrimp pellets, blanched vegetables (like spinach or zucchini), and occasional protein sources like frozen bloodworms.

Can shrimp live with fish?

Yes, but with caution. Most fish will eat baby shrimp if they can fit them in their mouths. Stick to very small, peaceful tank mates like Chili Rasboras or Otocinclus catfish.

Conclusion

Exploring the different types of pet shrimp is one of the most exciting journeys an aquarist can take. From the hardy and colorful Neocaridina to the majestic, fan-waving Bamboo shrimp, there is a species to fit every tank size and skill level.

Remember, the key to a thriving colony is stability and patience. By matching your water parameters to your chosen species and providing plenty of live plants, you will create a miniature underwater world that is both beautiful and fascinating to watch.

If you are just starting out, I highly recommend beginning with maintaining cherry shrimp. Once you see that first berried female and the tiny shrimplets that follow, you will be hooked on the hobby for life. Happy shrimp keeping!
