Amano shrimp are known for their exceptional algae-eating abilities, these shrimp are a great addition to larger planted aquariums but are too large for a 1 gallon shrimp tank!

6 Types Of Shrimp For A One Gallon Shrimp Tank

Choosing The Best Shrimp Based On Care Level

When setting up a 1-gallon shrimp tank, it’s essential to choose the right shrimp species based on their care requirements and compatibility with the tank’s limited volume. Consider the following guidelines:

  • For beginners: Cherry Shrimp are an excellent option for beginners, as they adapt well to various water conditions and have a higher rate of breeding.
  • For intermediate and advanced hobbyists: Caridina species, such as Crystal Red Shrimp and Bee Shrimp, are suitable for those with more experience maintaining stable water parameters and providing specialized care.
  • For algae control breeding tanks: Ghost or Amano Shrimp are efficient algae eaters and can help keep a planted tank clean, but be aware of the space limitations in a 1-gallon tank.

The majority of people who look to build a 1 gallon shrimp tank usually do it for the viewing pleasure so cherry shrimp or one of the other types of Neocaridina recommended above will be the best option.

Comparing Tank Sizes

When setting up a 1-gallon shrimp tank, it’s essential to consider different tank sizes and their benefits. Nano tanks, which typically have a capacity of 1 to 10 gallons, are popular choices for shrimp enthusiasts due to their compact size and lower maintenance requirements.

Most people instantly choose a 1 gallon tank due to their small size and low price. However, larger tanks, such as a 5 gallon tank, offer several advantages that can make it easier to maintain a healthy environment for your shrimp.

If you are an absolute beginner, we would highly recommend that you opt for a 3 or 5 gallon shrimp tank due to both being far easier to maintain.

  • Stability: Larger tanks provide more stable water parameters, which is crucial for shrimp health. Fluctuations in temperature, pH, and other factors occur more quickly in smaller tanks, making them potentially less suitable for shrimp.
  • Flexibility: Bigger tanks allow for a more diverse selection of plants, hardscape materials, and shrimp species. They also provide more room for shrimp to roam and interact, which can contribute to their well-being.
  • Ease of Maintenance: While nano tanks usually require less maintenance, the stability provided by larger tanks often means less frequent water changes and adjustments to maintain optimal conditions.

That said, most people with prior aquarium keeping experience should be able to setup a 1 gallon shrimp tank that thrives.

Most 1 gallon tank shapes can work for shrimp but standard four side long tank designs are usually the most beginner-friendly. Many people start with a 1 gallon bowl due to their lower price but these are usually more challenging to setup and maintain.

Choosing The Right Tank For Your Shrimp

When selecting the best tank size for your shrimp, it’s important to consider the following factors:

  • Species: Certain species of shrimp can thrive in 1-gallon tanks, such as Ghost Shrimp and Cherry Shrimp. However, other species may require more space or specific habitat requirements, making larger tanks more suitable.
  • Shrimp Population: If you plan to keep more than 10 cherry shrimp or 5 ghost shrimp, a bigger tank is advisable. This allows for better water quality management and reduces the risks associated with overcrowding.
  • Aquascaping and Decorations: If you want to create a more complex aquascape with a variety of plants, hardscape materials, and decorations, a larger tank will provide more space and flexibility for your design.
  • Budget and Space: While larger tanks offer several benefits, they also require more upfront investment and take up more room. Be sure to consider your available space and budget when choosing the right tank size for your shrimp.

A 1 gallon tank (four sided) will usually be a better option than a 1 gallon bowl so we would highly recommend that you opt for a tank if possible.

Equipping The Tank

Choosing The Right Equipment

To set up a 1-gallon shrimp tank, you will need to choose the right equipment.

Depending on your setup, this may include a filter, heater, light and other accessories necessary for maintaining a healthy environment for the shrimp. Some 1 gallon tanks will come with all of this included as standard but many budget-friendly tanks will require you to purchase these separately.

Different filters, heaters, and lighting systems mount to your tank in different ways so always follow the instructions on your specific equipment when setting your tank up.

We would highly recommend acquiring a water test kit to monitor water quality and a thermometer to track water temperature.

Setting Up Filtration System

A proper filtration system is vital for a shrimp tank, as it removes waste and promotes a healthy environment for the shrimp and plants.

In small tanks like a 1-gallon setup, a sponge filter is a suitable choice — they are cost-effective, efficient, and gentle enough for shrimp.

For added security, you can attach a filter guard to prevent shrimp from being sucked into the filter. Alternatively, an internal filter or a small canister filter can also be used if the flow rate is adjustable. Make sure to use a water conditioner to remove any harmful chemicals before adding shrimp to the tank.

Some people do use the Walstad Method of filtration that is based on live plants in the tank but this is very difficult when working with a 1 gallon tank due to size constraints so we don’t recommend it.

Maintaining Optimal Temperature And Lighting

It’s crucial to maintain a stable temperature in a shrimp tank. Most common freshwater shrimp species thrive at temperatures between 70-78°F (21-25°C).

An aquarium heater with a built-in thermostat is ideal for this purpose, as it automatically adjusts the temperature. Position the heater near the filter to ensure even heat distribution for the entire tank.

As for lighting, it is essential for plant growth and overall health of the tank. A simple LED light will suffice for a 1-gallon tank. Make sure to provide a consistent light cycle of around 8-10 hours per day, which can be automated using a timer.

Setting Up The Tank Environment

In this section, we will discuss how to create an optimal environment for your 1-gallon shrimp tank by focusing on three main aspects: choosing substrate, adding rocks and driftwood, and decorating the shrimp tank.

Choosing Substrate

You should always opt to use a suitable, shrimp-safe substrate for your 1 gallon shrimp tank with natural substrates usually being the best options. Here are our favourite options for smaller shrimp tanks:

  • Gravel: This is a common choice for shrimp tanks as it’s easy to clean and allows for proper water circulation. However, gravel may not be ideal for all shrimp species, as some prefer finer substrates.
  • Inert Sand: This finer substrate is a great option for shrimp species that like to burrow or graze. Sand also provides a more natural look to the tank.
  • Aquatic Soil: Aquatic soil can work well in certian tank setups but it is usually more challenging for beginners in smaller shrimp tanks. If you do plan to keep live plants in the tank then aquatic soil can be a great option.
  • Buffering Substrate: Sand or gravel specifically designed for shrimp tanks can help maintain optimal water parameters. For example, ADA Aquasoil or Fluval Shrimp Stratum can buffer water to maintain a lower pH, suitable for certain shrimp species like crystal red/black shrimp.

It’s crucial to research your chosen shrimp species and match the substrate to their preferences and requirements.

We recommend gravel of inert sand for anyone new to keeping shrimp and most people should be adding between 1 and 3 inches of their substrate to the bottom of their shrimp tank.

Adding Rocks And Driftwood

Incorporating a hardscape is a common part of designing your shrimp tank, as rocks and driftwood provide hiding places and grazing areas for your shrimp.

Unfortunately, a 1 gallon tank really doesn’t leave much free space for this type of decoration but with a little out of the box thinking, it can be done.

  • Rocks: Look for aquarium-safe rocks like Seiryu stones, Ohko stones (dragon stones), or lava rocks that won’t alter your water parameters. Rocks can be arranged to create cave-like structures or interesting visual features in your tank.
  • Driftwood: Choose from various driftwood options like Malaysian, Mopani, or Spider wood. Driftwood not only adds an appealing visual element but also releases beneficial tannins that can promote water quality.
  • Decorations: There are a number of commercially produced aquarium decorations that can work well in some shrimp tank setups. Depending on the size of the decoration, they may work well in a 1 gallon shrimp tank but we usually like to stick to natural decorations for our own tanks.

Always rinse rocks and driftwood before placing them in your tank to remove any dirt or debris.

Place any rocks or driftwood onto your substrate while trying to maximize the number of hiding spots for your shrimp without taking up much space.

Decorating The Shrimp Tank

Decorating the shrimp tank helps create an environment where your shrimp will feel safe and comfortable. Although space is tight in a 1 gallon shrimp tank, we highly recommend adding multiple hiding spots in the tank.

Here are some ideas for enhancing your shrimp tank decor while also providing hiding spots:

  • Aquascaping: Use live plants like Java moss, Anubias, or Marimo moss balls to create a lush, green environment. Live plants also help maintain water quality by absorbing nitrates.
  • Shrimp hideouts: Provide ceramic shrimp shelters, coconut shells, or terracotta pots for your shrimp to hide and breed in.
  • Leaf litter: Indian almond leaves or oak leaves can be added for further grazing areas and an additional source of beneficial tannins.

Remember to avoid overcrowding the 1-gallon tank and ensure there’s enough space for your shrimp to swim and explore their environment comfortably. The more you add, the less shrimp you are able to keep in the tank.

Most 1 gallon shrimp tanks will have plenty of hiding spots from rocks or driftwood but some live plants can be a great addition if space permits.

The Nitrogen Cycle and Shrimp Health

Understanding The Nitrogen Cycle

The nitrogen cycle is a crucial aspect of maintaining a healthy shrimp tank. It refers to the process in which harmful ammonia produced by shrimp waste and uneaten food breaks down into nitrite and eventually, nitrate. The nitrogen cycle ensures that toxic substances are removed from the water, promoting shrimp health and longevity.

In a 1-gallon shrimp tank, a stable nitrogen cycle is especially important due to the limited water volume.

Any imbalance in water parameters can quickly become harmful to your shrimp. By monitoring the nitrogen cycle, aquarists can avoid sudden spikes in ammonia or nitrite levels, which can be lethal to shrimp.

The nitrogen cycle consists of the following steps:

  1. Ammonia (NH3): Produced from shrimp waste and uneaten food, ammonia is toxic for shrimp even at low concentrations.
  2. Nitrite (NO2): Beneficial bacteria referred to as Nitrosomonas convert ammonia into nitrite, which is also harmful to shrimp.
  3. Nitrate (NO3): Nitrobacter bacteria convert nitrite into nitrate, a less harmful compound, which can be safely absorbed by live plants or removed through water changes.

You should always leave the water in your shrimp tank for around two weeks prior to adding your shrimp as this give the natural nitrogen cycle plenty of time to complete.

Beneficial Bacteria For Shrimp Health

To maintain a healthy nitrogen cycle in a 1-gallon shrimp tank, establishing a colony of beneficial bacteria is essential. These bacteria can be found naturally in most aquatic environments and grow on surfaces such as the substrate, filter media, and decorations.

The two critical types of beneficial bacteria for shrimp health are:

  • Nitrosomonas: These bacteria convert ammonia into nitrite, enabling the first step in the nitrogen cycle.
  • Nitrobacter: They take on the second step, converting nitrite into nitrate, a less harmful compound for shrimp.

By providing a suitable environment for beneficial bacteria to thrive, aquarists can ensure a stable nitrogen cycle in their 1-gallon shrimp tank. This can be achieved by:

  • Opting for a gentle filter, such as a sponge filter, to avoid removing the beneficial bacteria during filtration.
  • Adding live plants, which not only provide additional surface area for bacteria growth but also help to absorb nitrates from the water.
  • Avoiding overfeeding, as excess food can cause ammonia spikes and disrupt the nitrogen cycle.
  • Performing regular water changes to keep nitrate levels in check, ensuring the continued health and vitality of your shrimp.

By understanding and maintaining the nitrogen cycle, shrimp keepers can create a thriving and stable environment for their shrimp, contributing to their health and vibrant personalities.

You are able to purchase beneficial bacteria colonies online to use in your tank but this is usually a waste of time and money so we recommend you just wait for your shrimp tank to cycle.

Water Conditions

Maintaining Optimal Water Parameters

In a 1-gallon shrimp tank, maintaining optimal water parameters is crucial for the health and well-being of the shrimp. This includes monitoring and adjusting the pH level, ammonia, nitrite, nitrate, water hardness, and carbonate hardness (KH).

Always remember that the smaller the volume of water in the tank, the quicker water parameters can get out of range!

As we recommend cherry shrimp to our readers, here are the recommended water parameters for cherry shrimp in 1 gallon tanks:

  • pH level: Keep it between 6.5 and 8 if possible but there is a small amount of wiggle room.
  • Ammonia and Nitrite: Both should be at 0 ppm (parts per million) since they are highly toxic to shrimp.
  • Nitrate: Maintain a level below 20 ppm, ideally as close to 0 ppm as possible as high nitrate levels can stress shrimp.
  • Water Hardness (GH): A range of 6 to 8 dGH is usually suitable for most setups.
  • Carbonate Hardness (KH): Maintain a KH level between 3 and 15 dKH but some people recommend that you do your best to keep the KH level between 3 and 8 dKH if possible.

A standard freshwater aquarium test kit is able to test all of these water parameters to allow you to quickly and easily check that they are all in their correct ranges.

The Importance Of Regular Water Changes

Performing regular water changes is essential in a 1-gallon shrimp tank to maintain water quality and prevent the buildup of harmful substances.

Aim to replace 10-20% of the tank’s water with fresh, dechlorinated water once a week.

Regular water changes help maintain a healthy balance of minerals and nutrients and keep the water quality stable for shrimp to thrive. This process also helps reduce the risk of bacterial or fungal outbreaks that could harm the shrimp.

Due to the small size of the tank, you can usually complete your water change with a small container such as a cup rather than purchasing a siphon-based water change kit.

Monitoring Temperature Changes

Since shrimp are sensitive to temperature fluctuations, it is essential to monitor temperature changes in the 1-gallon shrimp tank.

Place a thermometer in the tank and maintain a consistent temperature suited to the shrimp species. Generally, freshwater shrimp species like Cherry Shrimp and Blue Bolt Shrimp do best in temperatures ranging from 70-78°F (21-25°C).

Cherry shrimp are a particularly hardy species of shrimp when it comes to their water temperature and can sometimes survive in water as low as 60°F but we usually recommend against this if possible.

Proper insulation and a small adjustable heater can help maintain the tank’s desired temperature. Also, avoid placing the tank in areas with direct sunlight or sudden drafts, which may cause rapid temperature swings, stressing the shrimp and potentially causing health issues.

Tank Maintenance And Shrimp Care

Feeding Your Shrimp

Shrimp are natural scavengers, which means they are capable of feeding on a wide variety of food sources. In a well-established tank, shrimp will primarily seek out biofilm to consume as part of their diet.

Biofilm is a thin layer of organic material that forms on surfaces in the aquarium. Supplement their diet with high-quality pellets or flake food once to twice a week in small amounts.

Providing additional nourishment by occasionally offering blanched vegetables such as spinach, zucchini, and cucumber is commonly done but totally optional.

Cleaning And Maintenance

Regular maintenance is essential to ensure a healthy environment for shrimp.

Perform water changes of approximately 10-15% once a week, making sure to use de-chlorinated water that matches the tank temperature.

Monitor water parameters using a reliable water test kit, and ensure the total dissolved solids (TDS) levels, as well as pH and temperature, remain consistent.

Cleaning the tank involves removing any debris, uneaten food, or dead plant matter that may accumulate.

A small siphon or turkey baster can be helpful in this process.As for the algae, some shrimp species will feed on it, but it’s essential to keep it under control and prevent excessive growth.

Frequently Asked Questions

For a 1-gallon shrimp tank, you will need an aquarium, a small shrimp-safe filter, a filter, a heater (optional depending on shrimp species and room temperature), and a thermometer. Additionally, you will need substrate, hardscape materials like rocks or driftwood, and suitable plants for the shrimp habitat.

The best substrate for a shrimp tank depends on the type of shrimp you plan to keep. For example, cherry shrimp and other Neocaridina species typically prefer inert substrates like sand or gravel. Caridina shrimp, such as crystal shrimp and blue bolt shrimp, often require specialized substrates with buffering capabilities to maintain slightly acidic water conditions.

Suitable plants for a small shrimp tank should require low light, be easy to maintain, and provide shelter for the shrimp. Some popular choices include Java moss, Anubias, and Java fern. Floating plants like duckweed and Salvinia can also be beneficial, as they provide cover and help maintain consistent water parameters.

Due to the small size of the tank, we advise against adding any additional tank mates to a 1 gallon shrimp tank.
