1.3. Brine Shrimp vs. Sea Monkeys: What’s the Difference?

While often used interchangeably, “brine shrimp” and “Sea Monkeys” aren’t exactly the same. Sea Monkeys are a specific hybrid strain of brine shrimp (Artemia nyos) bred for their larger size and longer lifespan. They were created in 1957 and marketed as instant pets, making them a popular novelty item. Both are easy to raise and care for, and the tips in this guide will help you care for both kinds of tiny crustaceans.

2. Setting Up Your Brine Shrimp Habitat

Creating a suitable environment is key to successfully keeping brine shrimp as pets. Here’s a step-by-step guide to setting up their habitat.

2.1. Choosing the Right Tank

Size Matters: A small tank (1-5 gallons) is sufficient for a small colony of brine shrimp. A larger tank (10+ gallons) can support a more substantial population and provide better water quality stability.
Material: Glass or acrylic tanks are both suitable. Acrylic is lighter and less prone to breakage, while glass is more scratch-resistant.
Shape: A rectangular or square tank is preferable for ease of maintenance and observation.

2.2. Preparing the Brine Solution

Brine shrimp thrive in saltwater with a specific salinity.

Salinity Level: Aim for a salinity of 30-35 parts per thousand (ppt), which is roughly equivalent to seawater. You can measure salinity using a hydrometer or refractometer.
Salt Mix: Use a high-quality aquarium salt mix specifically formulated for marine aquariums. Avoid table salt, as it contains additives that can harm brine shrimp.
Mixing: Dissolve the salt mix in dechlorinated water according to the manufacturer’s instructions. Aerate the solution for 24 hours before adding brine shrimp to ensure proper oxygenation.
Water Source: Use dechlorinated tap water or distilled water to avoid introducing harmful chemicals to your brine shrimp habitat.

2.3. Essential Equipment

Air Pump and Air Stone: An air pump and air stone are crucial for oxygenating the water and maintaining circulation.
Heater (Optional): If your room temperature fluctuates significantly, a small aquarium heater can help maintain a stable temperature between 77-86°F (25-30°C).
Lighting: Brine shrimp don’t require intense lighting. Indirect sunlight or a low-wattage LED aquarium light is sufficient.
Thermometer: Monitoring the water temperature is essential for maintaining optimal conditions.
Hydrometer or Refractometer: Measuring salinity accurately is crucial for brine shrimp health.

2.4. Setting Up The Tank: A Step-by-Step Guide

Clean the Tank: Thoroughly clean the tank with warm water and a non-toxic sponge. Avoid using soap or detergents, as they can be harmful to brine shrimp.
Add the Brine Solution: Carefully pour the prepared brine solution into the tank, leaving a few inches of space at the top.
Install the Equipment: Place the air stone at the bottom of the tank and connect it to the air pump. If using a heater, position it according to the manufacturer’s instructions.
Check the Parameters: Use a thermometer and hydrometer to ensure the water temperature and salinity are within the ideal range.
Wait Before Adding Shrimp: Allow the tank to stabilize for at least 24 hours before introducing brine shrimp. This will give the water time to equilibrate and allow any residual chlorine or chloramine to dissipate.

3. Acquiring Your Brine Shrimp

Now that your habitat is ready, it’s time to acquire your brine shrimp. You can obtain brine shrimp in two forms: cysts (dormant eggs) or live adults.

3.1. Brine Shrimp Cysts: Hatching Your Own

Hatching brine shrimp cysts is a cost-effective way to start your colony.

Source: Purchase high-quality brine shrimp cysts from a reputable aquarium supplier or pet store.
Hatching Container: You can hatch brine shrimp in a separate container or directly in the main tank. A cone-shaped hatching container with aeration is ideal for maximizing hatch rates.
Hatching Solution: Use a similar brine solution as described above for the hatching container.
Hatching Process: Add the cysts to the hatching solution and provide constant aeration. Maintain a temperature of 77-86°F (25-30°C) and provide constant illumination (2000 lux).
Hatching Time: Brine shrimp cysts typically hatch within 18-36 hours, depending on the temperature and quality of the cysts.
Separating Nauplii: Once hatched, the nauplii (newly hatched brine shrimp) can be separated from the unhatched cysts and eggshells using a light source. The nauplii are attracted to light, so you can concentrate them on one side of the hatching container and siphon them out.

3.2. Live Brine Shrimp: Instant Colony

Purchasing live brine shrimp allows you to start your colony immediately.

Source: Obtain live brine shrimp from a local aquarium store or online supplier.
Acclimation: Acclimate the brine shrimp to your tank water gradually by slowly adding small amounts of your tank water to the bag containing the shrimp over a period of 1-2 hours. This will help them adjust to the new water parameters and minimize stress.
Introduction: Gently release the brine shrimp into your tank.

4. Feeding Your Brine Shrimp: What Do They Eat?

Brine shrimp are filter feeders, meaning they consume microscopic particles suspended in the water.

4.1. Natural Food Sources

Algae: Brine shrimp primarily feed on microalgae, such as Spirulina and Chlorella. You can culture your own algae or purchase commercially available algae suspensions.
Bacteria: Brine shrimp also consume bacteria and other microorganisms present in the water.

4.2. Artificial Food Sources

Yeast: Brewer’s yeast is a readily available and inexpensive food source for brine shrimp. However, it can quickly foul the water if overfed.
Flour: Wheat flour or soybean flour can also be used as a supplemental food source.
Commercial Brine Shrimp Food: Several commercial brine shrimp foods are available, formulated to provide a balanced diet.
Egg Yolk: Small quantities of powdered egg yolk may also be used.

4.3. Feeding Schedule and Quantity

Frequency: Feed brine shrimp 1-2 times per day.
Quantity: Feed sparingly, only as much as the brine shrimp can consume within a few hours. Overfeeding can lead to water quality issues.
Observation: Monitor the water clarity and adjust the feeding quantity accordingly. If the water becomes cloudy or murky, reduce the amount of food you’re adding.

4.4. Enrichment

Enriching brine shrimp with essential fatty acids and vitamins can significantly improve their nutritional value, especially if you’re feeding them to fish.

Selcon: Selcon is a commercially available enrichment formula that contains essential fatty acids, vitamins, and amino acids.
DIY Enrichment: You can also create your own enrichment formula using fish oil, vitamins, and other supplements.

5. Maintaining Water Quality: The Key to Success

Maintaining optimal water quality is crucial for the health and longevity of your brine shrimp colony.

5.1. Regular Water Changes

Frequency: Perform partial water changes (20-30%) every 1-2 weeks.
Procedure: Siphon out the old water from the bottom of the tank, being careful not to disturb the brine shrimp. Replace it with freshly prepared brine solution that is the same temperature and salinity as the tank water.

5.2. Monitoring Water Parameters

Temperature: Maintain a stable temperature between 77-86°F (25-30°C).
Salinity: Keep the salinity between 30-35 ppt.
pH: Aim for a pH of around 8.0.
Ammonia and Nitrite: These toxic compounds should be kept at zero. Regular water changes and proper filtration (if used) will help maintain water quality.

5.3. Avoiding Overcrowding

Overcrowding can lead to poor water quality and increased stress on brine shrimp.

Density: Maintain a density of no more than 10-20 brine shrimp per liter of water.
Thinning: If your colony becomes too large, you can remove some of the brine shrimp and use them as fish food or give them away to other aquarists.

5.4. Siphoning Debris

Use a small siphon to remove uneaten food, waste, and other debris from the bottom of the tank regularly. This will help prevent the buildup of harmful substances and maintain water clarity.

5.5. Using Filtration (Optional)

While not essential, a small sponge filter can help improve water quality by removing particulate matter and providing a surface for beneficial bacteria to colonize.

6. Brine Shrimp Lifecycle and Reproduction

Understanding the brine shrimp lifecycle is essential for maintaining a healthy and sustainable colony.

6.1. Nauplius Stage

The nauplius is the first larval stage of brine shrimp. It is small, brownish in color, and swims using its antennae. Nauplii feed on yolk reserves initially and then transition to filtering microscopic particles from the water.

6.2. Juvenile Stage

As the nauplius molts and grows, it enters the juvenile stage. The juvenile brine shrimp resembles a miniature adult and continues to feed and grow.

6.3. Adult Stage

Adult brine shrimp reach a size of about 8-20 mm, depending on the strain and environmental conditions. They have elongated bodies with feathery appendages used for swimming and filter-feeding.

6.4. Reproduction

Brine shrimp reproduce sexually and asexually, depending on environmental conditions.

Sexual Reproduction: In favorable conditions, brine shrimp reproduce sexually, with males and females pairing up to produce fertilized eggs.
Asexual Reproduction (Parthenogenesis): In stressful conditions, such as high salinity or low oxygen levels, female brine shrimp can reproduce asexually through parthenogenesis, producing live nauplii without fertilization.
Cyst Production: In harsh conditions, brine shrimp produce dormant cysts that can survive for years in a dried state. These cysts hatch when conditions become favorable again.

6.5. Promoting Reproduction

To encourage reproduction in your brine shrimp colony:

Maintain Optimal Water Quality: Ensure the water temperature, salinity, and pH are within the ideal range.
Provide Adequate Food: Feed the brine shrimp a nutritious diet to support growth and reproduction.
