Top 6 Best Shrimp Tanks Reviews

1. Fluval Spec III 2.6 Gallon Shrimp Aquarium Kit


Designed for absolute beginners, the Fluval Spec III is simply perfect. All you need is to fill this shrimp tank with water and your favorite decorations. Once you have conditioned the water, you can start putting up to 25 small species of freshwater shrimp. It is that simple. Fluval designed the Spec III for ease of operation without neglecting the aesthetics of the shrimp tank.

Keep in mind that the Spec III’s motor pump can be very unforgiving to very small shrimp. You will want to dial the pump to the lowest possible setting; lest your shrimp will be short-lived. Other than that, the Fluval Spec III can make your journey into the world of shrimp hobby a lot more fun and fulfilling.


  • Very compact and sleek design
  • Hidden filter mechanism
  • Real glass construction
  • Easy to maintain and clean
  • Good lighting


  • Filter pump too powerful for young and small shrimp

2. MarineLand 5 Gallon Portrait Glass LED Shrimp Aquarium Kit


Worried you do not have enough space on your table to accommodate a standard shrimp tank? We recommend getting the MarineLand Portrait Shrimp Aquarium. The tall design of the MarineLand should allow you to put interesting decorations around it. The base is as stable as a conventional shrimp tank. This maximizes tabletop space.

The aquarium is easy to clean and comes with good lighting for your shrimp. The pump has a whisper-quiet operation. The glass canopy also protects your aquarium from any debris that may fall into the water. It looks lovely, too.

Even though the filter compartment can be challenging to clean, the MarineLand Shrimp Aquarium makes for a lovely kit for both beginning and seasoned aquatics hobbyists.


  • Elegant ‘portrait’ orientation
  • Very silent filter motor
  • Surface is easy to clean
  • Solid and sturdy base
  • Sleek and elegant design


  • Filter compartment a bit tricky to clean

3. biOrb CLASSIC 8 Gallon Freshwater Shrimp Tank with LED


The biOrb CLASSIC is not your ordinary fish bowl that your young child may have kept sitting on her bedside table. This is a large-capacity aquarium that can be the permanent home to at least 40 shrimp. What is even more admirable is that the fish bowl already comes with a 5-stage filter that will keep the water as healthy as possible for your shrimp. There is even an LED lighting to let the fish bowl stand out at night, while fostering better shrimp health.

Our only issue is that the biOrb is not made of glass. The company used clear acrylic. What is good about this is that the fishbowl is a lot lighter than your conventional fish bowl. This makes it a great tank for your crustacean friends.


  • Classic fish bowl shape
  • Solid and stable base
  • Comes with integrated filter
  • Good LED lighting
  • Elegant design


  • Acrylic construction

4. Aqueon 10 Gallon Shrimp Tank Aquarium LED Kit


The Aqueon has got to be one of the most eye-catching shrimp tanks we have ever seen. You will love the clear glass panels that surround the tank. We personally love the low-profile hood that protects the aquarium and keeps the water stable. What sold us to the Aqueon is its completeness as a kit. It already has a filter, water conditioner, fish food, thermometer, and a fish net. You only need to buy your shrimp and other decorations to set the Aqueon.

While the hood is one of the Aqueon’s strongest features, there is a flaw in its design. It does not come with a hinge that should make opening and closing the hood a lot easier. Nevertheless, we still believe that the Aqueon is the perfect shrimp tank.


  • Complete shrimp tank kit
  • Sturdy glass construction
  • Reliable filter mechanism
  • Comes with a heater
  • Good lighting


  • Tank hood does not have a hinge

5. Fluval Sea Evo Saltwater Shrimp Tank Aquarium Kit


If you are into saltwater species of shrimp, then Fluval’s Sea Evo is the one to get. The large capacity design of this tank should accommodate the different corals and marine plants that will serve as natural elements to your shrimp’s habitat. The integrated light system can also provide you with a remarkable view of the tank, day and night. The filter keeps the saltwater clean for your shrimp. The lid also comes with an opening for feeding your shrimp.

Our only gripe about the Sea Evo is that the lid does not come with a hinge. You will have to remove the whole thing if you intend to give the tank a thorough cleaning. Other than that, the Fluvial Sea Evo is a wonderful choice for avid shrimp hobbyists.


  • Large capacity tank
  • Multi-functional lid
  • Elegant design
  • Excellent day and night illumination
  • Hidden filter compartment


  • No hinge on lid

6. Tetra 20 Gallon Freshwater Shrimp Tank Kit


Shrimp are known to move around a lot. That is why we believe this shrimp tank from Tetra is the best. Measuring 2.5 feet from side to side and about a foot deep, the Tetra provides ample space for your shrimp to swim around. We also love the decorative elements included in the shrimp tank. The two dome lights may look unappealing compared to more advanced LED hood lighting systems. However, it does provide good illumination that doubles as a reliable heater for your crustacean friends.

One issue we had about the Tetra shrimp tank is the inefficiency of its filtering mechanism. We can only assume that it has something to do with how the filter is designed as a decorative element. Nevertheless, this is still a great shrimp tank to buy.


  • Great as a community aquarium
  • Solid construction
  • Comes with decorative elements
  • Good heating mechanism
  • Very stable base


  • Issues about filter efficiency

Shrimp Tanks Buying Guide

Buying an aquarium for your colorful shrimp is almost the same as picking the right tank for your fish. It is important that you have a good working knowledge of the species of shrimp that you intend to keep in the tank. Here are a few pointers to help you decide on the best possible tank for your shrimp.

Pick the right tank size

The size of the shrimp tank depends on the number of shrimps that you want to keep. The ideal ratio of shrimp to a gallon of water is about 5-10:1. As such, a 2.5-gallon shrimp tank is enough to house 13 to 25 shrimp.

The current recommendation for starters is 10 gallons. The main advantage of a larger shrimp tank is that the water tends to be more stable in terms of temperature, chemical composition, and other water parameters.

Do not forget the filter

What is critical here is that the suction of the filter pump should not be too strong that it can injure young and very small species of shrimp.

A popular choice is a simple sponge filter because this is safer and gentler for shrimp. This device is perfect for shrimp tanks smaller than 20 gallons. For bigger tanks, a canister filter is often advisable. However, one should never use this kind of filter in a shrimp-only tank.

Choose the right substrate

The appropriate substrate of the shrimp tank depends on the species of shrimp that you are going to keep. For example, Neocardina shrimp need inert substrate that can maintain the water’s pH at 6.8 to 8.0.

Gravel is perfect for those who will be adding aquatic plants in their shrimp tank. You can also pick sand substrate that has larger-than-usual grain. This substrate does not trap dirt, making it easier to clean.

What is a Shrimp Tank?


A shrimp tank looks like an aquarium. Instead of housing fish, however, the aquarium serves as the habitat of certain species of shrimp. The shrimp tank contains a filter and substrate. Some tanks also come with a heater, aquatic plants, and other features to help maintain the ideal environment for the shrimp.

Types of Shrimp Tanks

People classify shrimp tanks according to the type of shrimp that they put in the aquarium. Shrimp tanks can also be classified according to whether they are planted or not.

Freshwater Shrimp Tank

This is a kind of aquarium that is perfect for housing freshwater species of shrimp. This can include the Red Cherry, Ghost, Snowball, Blue Tiger, Panda, and Babaulti, among others. Freshwater aquariums are easier to maintain and require very minimal operating costs. These tanks may look dull if you do not provide good lighting and aquarium decorations.

Saltwater Shrimp Tank

Marine aquariums are the best manmade habitat for saltwater shrimp. Two of the most popular species of saltwater shrimp are the Common Marbled and the Pinecone Marble. Marine or saltwater shrimp tanks are notorious for their strict maintenance requirements. The main advantage is that these shrimp tanks can provide you with a very accurate recreation of the ecosystem under the ocean waves.

Planted Aquarium

Shrimp love to hide behind the foliage and eat algae. Plants help oxygenate the water, keep the aquarium clean, and maintain the ideal pH of the water. The best part about planted shrimp tanks is that they are very beautiful to look at. Unfortunately, maintenance can be very challenging.

Bare Aquarium

This is the simplest shrimp tank you will ever see. There are no plants, no substrate, no decorations, nor any other element. This is ideal for those who breed shrimp. The bare tank allows for ease of access to young shrimp, while also making cleaning easy.

Why Do You Need Shrimp Tanks?

Shrimp are very delicate aquatic creatures. They are very sensitive to minute changes in the chemical characteristics of water. These crustaceans are known to be very sensitive to metals, especially copper. Water supplements that contain copper can be fatal to shrimp.

While shrimp are adaptable and hardy, it is still best to put them in a container where you can monitor and control the parameters of the water. That is why your choice of a shrimp tank is very important. You need to maintain the ideal pH of the water so that your shrimp will thrive. The same is true with the water temperature. If you do not have a shrimp tank, it might be more difficult to monitor minute changes in water temperature, pH, and chemistry.

You will also need a shrimp tank to showcase the unique habitat of these aquatic creatures. For the most part, aquariums serve to enhance the overall beauty of a room. Certain species of shrimp are also more colorful than others. These species can add to the elegance of the aquatic ornament. This is especially true for saltwater shrimp tanks. The aquarium can deliver an under-the-ocean visual experience right in the comfort of your room.
