Shrimp tanks can be polluted by bacteria, and this can be detrimental to the health of the shrimp. Bacterial infections are often difficult to spot, but they spread quickly and can become fatal. In some cases, the shrimp may only live a few more days after the onset of the infection. However, certain types of bacteria, such as biofilm, are beneficial to shrimp tanks as they serve as a food source and help keep the shrimp healthy and happy.

Bacterial infections: These can be difficult to spot and are often only noticed when they have become fatal
Bacterial infections are a common issue for shrimp tanks. They are often hard to spot and can be fatal to shrimp.
Bacterial infections are usually caused by poor water quality, such as high levels of nitrites, nitrates, or ammonia, and high organic waste. This can be due to infrequent water changes, food remains, and residual plant debris. High temperatures can also encourage bacterial growth.
Some bacterial infections can be identified by visible spots on the shrimp's carapace or internal organs. However, in many cases, the infection is only noticed when the shrimp start dying.
To prevent bacterial infections, it is important to maintain good water quality, provide a proper diet to strengthen the shrimp's immune system, and minimise stress factors such as poor water quality and transport.
If you suspect a bacterial infection in your shrimp tank, it is recommended to isolate any infected or dead shrimp to prevent the spread of the disease. Unfortunately, there is no specific treatment for bacterial infections in shrimp, and antibiotics are not recommended as they can be harmful to the shrimp.
Bacterial infections in shrimp tanks can be challenging to identify and treat. These infections are often caused by poor water quality, such as high levels of nitrites, nitrates, or ammonia, which can weaken the shrimp's immune system. High organic waste in the water, due to infrequent water changes, food remains, and residual plant debris, can also contribute to bacterial growth. Additionally, high temperatures can promote the proliferation of bacteria.
The symptoms of a bacterial infection may include visible spots on the shrimp's carapace or discolouration of the internal organs. However, in many cases, the infection is only noticed when the shrimp start dying. To prevent bacterial infections, it is crucial to maintain good water quality and provide a proper diet to strengthen the shrimp's immune system.
If you suspect a bacterial infection in your shrimp tank, it is important to act quickly. Isolate any infected or dead shrimp to prevent the spread of the disease. Unfortunately, there is no specific treatment for bacterial infections in shrimp. Antibiotics are not recommended as they can harm the shrimp's beneficial bacteria and may not be effective against the specific bacteria causing the infection.
Maintaining good water quality and shrimp health is key to preventing and managing bacterial infections in shrimp tanks. Regular water changes, proper diet, and stress reduction are crucial. Additionally, when introducing new shrimp, it is important to source them from reputable farms with strict veterinary control to minimise the risk of introducing pathogens into your tank.
If you notice any signs of a bacterial infection, such as spots on the shrimp's carapace or abnormal behaviour, it is important to act quickly. Isolate the affected shrimp and, if possible, treat them in a separate hospital tank. While there is no guaranteed cure for bacterial infections in shrimp, creating optimal conditions can help support the shrimp's immune system and improve their chances of recovery.
Some bacterial infections in shrimp can be identified by visible signs, such as spots or discolouration on the carapace or internal organs. However, in many cases, bacterial infections are difficult to detect and may only be noticed when the shrimp start dying. Therefore, it is important for shrimp tank owners to be vigilant and act quickly if they suspect any health issues in their shrimp.

Chitinolytic bacterial disease: This affects the outer organs of shrimp and is caused by bacteria that possess the enzyme chitinase
Bacterial infections are a common issue in shrimp tanks, especially during the summer months. Poor water quality, overcrowding, and stress are factors that can lead to bacterial infections in shrimp.
One such bacterial disease that affects shrimp is Chitinolytic Bacterial Shell Disease, also known as Chitinolytic bacterial disease. This disease is caused by bacteria that possess the enzyme chitinase, which can degrade the chitin in a shrimp's carapace, leading to shell damage. The affected shrimp exhibit dark spot lesions and eroded wounds on their exoskeleton, which can progress to infect their internal organs.
Chitinolytic bacterial disease is caused by a variety of bacteria, including Vibrio, Aeromonas, Pseudomonas, Alteromonas, Flavobacterium, Spirillum, Moraxella, Pasteurella, and Photobacterium. These bacteria are not limited to a single species and can affect both wild and cultured shrimp, as well as other crustaceans like lobsters, crabs, and crayfish.
While there is no known treatment for Chitinolytic bacterial disease, it can be managed by reducing crowding, practising proper husbandry, and maintaining good system hygiene. Early detection and treatment are crucial, as the disease is contagious and can spread throughout the shrimp colony.

Overfeeding: This can lead to an increase in ammonia, nitrite, and nitrate levels, which are toxic to shrimp
Overfeeding your shrimp can have a detrimental effect on your water parameters. It can lead to a rise in ammonia, nitrite, and nitrate levels, which are toxic to shrimp.
Ammonia is a toxic chemical that naturally occurs in shrimp tanks. It is produced by shrimp as waste and can also come from leftover food that has started to rot. High levels of ammonia can cause stress to your shrimp, as well as chemical burns to their bodies. It is a common cause of death in new shrimp tanks. Therefore, it is important to keep ammonia levels as close to zero as possible. Regular water changes can help to keep ammonia levels under control.
Nitrite is also toxic to shrimp and can be harmful even in small amounts. It is an intermediate product formed when beneficial bacteria in the tank break down ammonia.
Nitrate is less toxic than ammonia and nitrite but can still pose a risk to shrimp if levels are too high.
Overfeeding can cause excess food to quickly break down and produce ammonia, leading to elevated levels of ammonia and nitrate in the tank. This can be particularly problematic with soft foods like vegetables, as they tend to decay faster. Therefore, it is important to only feed your shrimp enough food that they can consume within a few hours. Using a feeding dish can make it easier to remove any leftover food before it starts to rot.
In addition to overfeeding, there are other factors that can contribute to high levels of ammonia and nitrate in a shrimp tank. These include overcrowding, inadequate filtration, and poor water quality due to infrequent water changes or improper tank maintenance.
To reduce ammonia and nitrate levels in your shrimp tank, it is recommended to perform regular water changes, use an effective filtration system, and avoid overfeeding. Live plants can also help to absorb excess nutrients and keep ammonia and nitrate levels under control.

Poor water quality: Shrimp are sensitive to changes in water chemistry and require clean water to stay healthy
Shrimp are highly sensitive to changes in water chemistry and require clean water to stay healthy. Poor water quality can lead to bacterial infections, with harmful bacteria such as Vibrio, Aeromonas, and Pseudomonas affecting shrimp, particularly in overcrowded tanks with high levels of organic waste.
To maintain a healthy shrimp tank, regular water changes are necessary. Water changes help to reduce free-floating algae and lower tannin colour in blackwater tanks. It is recommended to start with a plan to change 10% of the water every two weeks, ensuring consistency and stability in water parameters. Performing water changes too frequently can stress the shrimp and cause health issues.
It is crucial to measure core water parameters such as General Hardness (GH) and Carbonate Hardness (KH) regularly to determine if water changes are needed. Additionally, nitrates should be kept below 20ppm, and climbing nitrate levels may indicate the need for increased water changes or the addition of floating plants. Dirty water, indicated by a buildup of dirt and waste, is another sign that more water changes are required.
When performing a water change, it is important to prepare the new water, remove the old water, and drip acclimate the new water back in. Using reverse osmosis (RO) water and adding shrimp salt allows for more precise control over water parameters.
Maintaining water quality is crucial for shrimp health, and shrimp are sensitive to even slight changes in their environment.

Scutariella Japonica: A common parasite that affects the gills or mantle of infected shrimp, causing difficulty in breathing, eating, and survival
Scutariella Japonica is a flatworm parasite that infects freshwater shrimp. It is one of the most common shrimp parasites and is typically found in the gills or mantle of infected shrimp. While generally harmless in small numbers, heavy infestations can cause significant harm to shrimp.
Identification
Scutariella Japonica manifests as small, white, branch-like appendages measuring 1 to 2 millimetres on the shrimp's head or rostrum. These parasitic flatworms attach themselves between the eyes or on the rostrum, rarely appearing on other body parts. The presence of eggs, laid in rows behind the head within the gill chamber, is another identifying factor.
Effects on Shrimp
Although Scutariella Japonica does not typically kill shrimp, heavy infestations can interfere with the shrimp's breathing and mobility, leading to health complications and, in severe cases, mortality. The parasites exploit the shrimp as a substrate for their survival, and their presence in large numbers can cause difficulty in breathing, eating, and survival for the shrimp.
Treatment Options
- Freshwater Aquarium Salt: Dissolve 1 tablespoon of freshwater aquarium salt in a cup of aquarium water, then dip the infected shrimp for 30-60 seconds. Repeat as needed.
- Seachem ParaGuard: Administer a dose of 5 mL for every 40 litres (10 gallons) daily for about a week.
- Praziquantel: Effective against parasitic worm infections. Use a dose of 2.5 mg per litre (10 mg per gallon) and repeat after 2-3 weeks to target newly hatched eggs.
- Fenbendazole: Commonly used for deworming. Apply 0.1g per 10 gallons, repeating the dose in 2-3 weeks. Caution: May be harmful to snails.
- Internal Parasite Clear and Other Treatments: Use half the recommended dose of products like Benibachi Planaria Zero and No Planaria for 3 days, followed by a 30-40% water change.
Prevention
Maintaining good water quality is crucial for preventing and managing Scutariella Japonica infestations. Regularly monitor water parameters and ensure proper water management to provide a healthy environment for your shrimp.
