Starting Your Culture
Temperature
Different Clam shrimp species thrive at different temperatures. Refer to the recommended temperature ranges for each genus to ensure optimal conditions.
Container Size
Use a glass container that holds between 1 and 3 gallons. Clean it with a diluted bleach solution only. Avoid soap or detergents, as residue can be harmful to Clam shrimp.
Lighting
To replicate a natural day–night cycle, place the tank near a bright window or provide approximately 8 hours of LED lighting per day.
Water
Spring water is recommended because it contains minerals essential for Clam shrimp health. Avoid tap water, as it may contain chlorine, chloramines, or heavy metals that can be detrimental.
Substrate
Using substrate is optional, but it is highly beneficial and strongly recommended for maintaining a stable and productive Clam shrimp culture. A proper substrate provides both mineral support and a natural source of microorganisms that young shrimp rely on.
A suitable substrate should consist primarily of sand, with a small portion of organic matter such as composted material.
Allow the substrate to sit for 1–2 days before adding eggs so that microorganisms can establish. Gently stir the substrate to help it settle; it may take up to a full day for all material to sink.
Aeration
Aeration is optional but can improve hatching rates, increase algae growth, and support a larger population. Use only a gentle airflow, as Clam shrimp are weak swimmers and can be injured by strong currents.
Adding Eggs
Add the egg packet once the tank is prepared. Hatching typically occurs 1–3 days after hydration, depending on temperature and species.
Clam Shrimp Care
Hatching
Newly hatched nauplii are extremely small and may be difficult to see. To observe them:
Darken the room
Shine a flashlight along the side of the container
The nauplii will swim toward the light
Initial Feeding
Mix 1 spoon of baker’s yeast into 1/4 cup of dechlorinated water. Ensure the mixture is fully dissolved.
Add 3–5 drops of this solution per gallon. Newly hatched Clam shrimp may not require feeding immediately, as they often have sufficient microorganisms available in the substrate.
Feeding as They Grow
Feed once daily, or every other day if the tank is lightly stocked.
Add 5–10 drops of the food solution per gallon.
The water should appear slightly hazy, not milky.
Overfeeding can cause oxygen depletion and bacterial blooms.
If the water becomes cloudy, stop feeding until it clears. Introduce food gradually as the biological filter matures and the nitrogen cycle stabilizes.
Alternative foods:
Green water (algae culture)
Powdered fish food
Water Maintenance
Avoid full water changes. Instead:
Top off evaporated water with fresh spring water
If surface scum develops, remove it gently with a piece of paper towel
Long-Term Care
Lifespan
Clam shrimp typically live 6–32 weeks with proper care. As adults die naturally, eggs will accumulate at the bottom of the tank. Allow the tank to dry completely, then rehydrate to begin a new generation.
Understanding the Nitrogen Cycle
The nitrogen cycle is the natural process by which beneficial bacteria convert toxic waste products into safer compounds. In a Clam shrimp tank, this cycle is essential for maintaining stable, healthy water conditions.
Ammonia (NH₃)
Produced by decaying food, waste, and dead organisms. Ammonia is highly toxic to Clam shrimp.
Nitrite (NO₂⁻)
Beneficial bacteria convert ammonia into nitrite. Nitrite is also harmful, though slightly less so.
Nitrate (NO₃⁻)
A second group of bacteria converts nitrite into nitrate. Nitrate is far less toxic and can be tolerated at low to moderate levels.
A stable nitrogen cycle helps prevent sudden die‑offs and supports long-term health.
Health Indicators
Signs of Healthy Clam Shrimp
Active, steady swimming
Clear, well‑formed bodies
Consistent feeding behavior
A visible, full gut line
Brown or green coloration is normal and depends on the food source
Signs of Unhealthy Clam Shrimp
Lethargy or weak swimming
Floating or sinking without control
Pale or empty gut line
Red or inflamed gills (in species where visible)
Rapid die‑off of multiple individuals
Frequently Asked Questions
Why did my shrimp suddenly die?
Sudden die‑offs can occur for several reasons:
Overfeeding leading to oxygen depletion
Unstable or incomplete nitrogen cycle
Temperature fluctuations
Contamination from soap, detergents, or metals
Low oxygen levels
Old age (especially around the 3‑month mark)
If a die‑off occurs, allow the tank to dry completely. The eggs left behind will remain viable and can be rehydrated to start a new generation.
Why is the water cloudy?
Cloudy water is usually caused by a bacterial bloom. This is common in new setups and is not always harmful. A moderate bacterial bloom can be beneficial, as these microorganisms serve as an additional food source for Clam shrimp.
However, a bloom also indicates that the system is operating near the edge of instability. If the nitrogen cycle is not yet fully established, the sudden increase in bacterial activity can rapidly consume oxygen or cause spikes in ammonia and nitrite. This can lead to a system crash if not monitored.
Cloudiness should gradually clear on its own as the biological filter stabilizes. During this period:
Do not feed until the water begins to clear
Avoid disturbing the substrate
Allow the beneficial bacteria time to establish
It is a balancing act: early bacterial blooms can support the developing ecosystem, but they also signal that the tank is still maturing and vulnerable to sudden changes.
IF ITS GREEN WATER...in which hopefully a healthy algae colony has established, pump up the aeration! this is usually super beneficial algae that uptakes waste but needs more oxygen to support algae and Clam shrimp growth! feed as normal.
Why aren’t my eggs hatching?
Possible causes include:
Temperature outside the ideal range
Insufficient oxygenation
Lack of light
Water that is too soft or too salty
