How to Identify and Treat Sick Ghost Shrimp - Complete Guide for Aquarists in Australia

Ghost shrimp (also known as glass shrimp) are hardy, peaceful creatures often chosen by aquarists for their algae-eating abilities and translucent appearance. But just like any aquatic animal, ghost shrimp are not immune to illnesses. Early detection of disease is crucial—not only to save the affected shrimp but also to protect the health of your entire tank.

In this guide, we’ll walk you through:

• Common signs of sickness in ghost shrimp
  
  

• The causes of illness
  
  

• Effective treatment and prevention methods
  
  

• Tips on maintaining a healthy environment
  
  

Let’s dive into the world of ghost shrimp health!

A. Common Signs of Illness in Ghost Shrimp

Ghost shrimp are small, subtle creatures. When they fall sick, the symptoms can be easy to miss. Here are key signs to watch for:

1. Discoloration

A healthy ghost shrimp is almost fully transparent. If you notice:

• A milky or white appearance
  
  

• Dark spots forming inside the body
  
  

• Reddish or brown patches
  It could indicate a bacterial or fungal infection.
  
  

2. Lethargy or Slow Movement

If your ghost shrimp is:

• Staying in one spot for long hours
  
  

• Moving very little, even when disturbed
  
  

• Avoiding food
  It could be suffering from internal stress, low oxygen levels, or parasitic infestation.
  
  

3. Erratic Swimming

Wild or twitchy movements, swimming upside down, or floating near the surface are red flags. These could be symptoms of:

• Ammonia poisoning
  
  

• High nitrate/nitrite levels
  
  

• Heavy metal contamination
  
  

4. Moulting Problems

Ghost shrimp shed their exoskeletons regularly. Warning signs include:

• Difficulty moulting
  
  

• Getting stuck in old shells
  
  

• Deformities post-moult
  This may suggest poor water quality or a calcium deficiency.
  
  

5. Unusual Body Shape or Clamped Legs

Clamped legs, curled tails, or a hunched posture may be due to:

• Bacterial or fungal infections
  
  

• Genetic issues
  
  

• Stress from aggressive tank mates
  
  

B. What Causes Ghost Shrimp to Get Sick?

Understanding the root of the problem is key to effective treatment. Here are the most common causes:

1.  Poor Water Quality

Ghost shrimp are highly sensitive to:

• Sudden changes in pH
  
  

• High ammonia or nitrite levels
  
  

• Copper or heavy metal contamination
  
  

2. Ideal Water Parameters:

• Temperature: 22–27°C
  
  

• pH: 6.5–8.0
  
  

• Ammonia/Nitrite: 0 ppm
  
  

• Nitrate: < 20 ppm
  
  

3.  Incompatible Tank Mates

Ghost shrimp are peaceful and should not be kept with aggressive fish such as:

• Betta fish (some individuals may nip)
  
  

• Cichlids
  
  

• Barbs
  
  

These fish can stress or injure your shrimp, leading to illness or early death.

4.  Poor Diet

Ghost shrimp require a balanced diet. If they lack nutrients, they can become weak and vulnerable to disease.
Offer them:

• Algae wafers
  
  

• Blanched vegetables (like spinach or zucchini)
  
  

• High-protein shrimp pellets
  
  

5.  Lack of Tank Maintenance

Overfeeding, unclean substrate, or infrequent water changes create a breeding ground for bacteria and parasites. Weekly tank care is essential.

C. How to Treat Sick Ghost Shrimp

When you notice signs of illness, act quickly but carefully. Here’s what to do:

1. Quarantine the Affected Shrimp

Immediately move the sick shrimp to a separate quarantine tank (2-5L is enough). This prevents the spread of infection and allows you to observe their behavior more closely.

2. Test the Water

Use an aquarium test kit to check ammonia, nitrite, nitrate, and pH levels in both tanks. If anything is off:

• Do a partial water change (20-30%)
  
  

• Remove waste and uneaten food
  
  

• Adjust pH or temperature gradually
  
  

3. Use Aquarium Salt (with caution)

Add a small amount of aquarium salt to the quarantine tank. It can help with stress and minor infections.
Dosage: 1 teaspoon per 4L of water
Warning: Never use table salt, and do not overuse salt with invertebrates. Monitor your shrimp carefully.

4. Consider Medication (Last Resort)

Some fungal or bacterial infections may need shrimp-safe treatments. Look for products labeled “safe for invertebrates.”
Examples:

• Seachem Paraguard
  
  

• API General Cure (in reduced doses)
  
  

Always research the ingredients and consult aquarium communities or specialists before using any chemical.

5. Improve Diet

Offer nutrient-rich food like:

• Crushed spirulina flakes
  
  

• Shrimp-specific sinking pellets
  
  

• Occasional boiled peas or spinach
  
  

This boosts immunity and helps your ghost shrimp recover faster.

D. Prevention: Keep Your Ghost Shrimp Healthy

Prevention is better than cure. Here’s how to keep your shrimp colony thriving:

1.  Regular Maintenance

• Change 20–30% of the water weekly
  
  

• Vacuum the substrate
  
  

• Clean the filter regularly (but not too aggressively)
  
  

2.  Provide a Natural Habitat

Ghost shrimp love:

• Live plants (Java moss, hornwort)
  
  

• Hiding spots (rocks, driftwood, shrimp tubes)
  A natural setting reduces stress and encourages healthy behavior.
  
  

3.  Choose Peaceful Tank Mates

Ideal companions for ghost shrimp include:

• Nerite snails
  
  

• Otocinclus catfish
  
  

• Cherry shrimp
  
  

• Small rasboras or endlers
  
  

4.  Buy from Trusted Sources

Buy ghost shrimp from reputable stores like Micro Aquatic Shop. Shrimp from healthy, well-maintained systems have higher chances of survival and fewer illnesses.

❓ FAQ: Sick Ghost Shrimp

1. Why is my ghost shrimp turning white?

This is often a sign of a bacterial or fungal infection—or that the shrimp is dying. Check water quality immediately and isolate the shrimp.

2. Can ghost shrimp get parasites?

Yes. Some may carry parasitic infections that show as worms inside their body or abnormal swelling. Quarantine and consult a vet or aquarist if unsure.

3. How long do ghost shrimp live?

On average, 1–1.5 years in a healthy tank. If yours die earlier, it may be due to poor water conditions or stress.

4. Is it normal for ghost shrimp to stop eating before moulting?

Yes. Some shrimp hide and become less active before a moult. If it lasts longer than 1–2 days, look for signs of illness.

 Final Thoughts

Caring for ghost shrimp means paying attention to the subtle signs of their health and happiness. With regular tank maintenance, a proper diet, and a peaceful environment, your shrimp can live full, vibrant lives. If illness strikes, act quickly with the right quarantine and treatment methods.
