Shrimp Diseases: Bacterial InfectionDiagnosis and Symptoms
QUOTE
The diagnosis of shrimp diseases is a very complex area and it is often not possible to distinguish at first sight which or if any disease is present. In many cases, livestock are already affected when an outbreak becomes visible. It may start with one dead shrimp each day, and while water parameters may seem suitable, it can lead to molting problems and further fatalities. If shrimp turn white inside the body and their usual coloration fades, this only shows there is a problem in the circulation and a lack of oxygen in the body. Any fungal or bacterial infection in the body or harming of the gills can cause this. Most of these infections are secondary, meaning the actual cause is environmental, reducing the resistance of the shrimp. Some affected shrimp even lose antenna and other extremities (e.g. legs, eyes). In a later phase, shrimp are inactive and may ‘stagger’ through the water. These shrimp are more likely to die sooner rather than later. Some bacteria populations also erode the exoskeleton and shell: rusty, brown or black spots and holes are the visible signs of this. Also the gills can sometimes be damaged by bacterial pathogens.
Biological and Organic Treatment methods
QUOTE
-The most important thing to do is: to improve water quality which in turn reduces harmful bacteria.
-Clean the tank and gravel from mud and leftovers regularly.
-Check your filtration set up and clean pipes and filter if it is very dirty or running slow.
-Use filter booster bacteria like Mosura Bacter 9 to raise beneficial bacteria (probiotics) in your tank.
-Inject oxygen with a simple air stone or similar.
-Do change the water daily, with a minimum of 80% (not less!) for at least two weeks. This lowers the quantity of bacteria. If you change less than 80% of the water, bacteria will bloom again. It is important that the incoming fresh water has the same water parameters as your tank. Changes in parameters e.g. pH or GH will stress -your shrimp even more.
-Feed less in both frequency and amount and remove ill or dead shrimp as soon as possible.
-Add Indian Almond Leaves ('Ketapang Leaves') to support/promote healing.
-Reduce stress for your shrimp.

QUOTE
Hydras are tiny animals, which are closely related to jellyfish. Green Hydras live in fresh water, such as streams, rivers, lakes, and ponds. They are very common.
A Green Hydra can grow up to 30 millimeters long, but usually they are less than 15 mm. Hydras are found in shallow water, where they attach themselves to plants, stones, twigs, or other objects. Unlike their jellyfish cousins, they don't like to float around.
rey of Green Hydras includes aquatic insects, crustaceans (such as water fleas and scuds), flatworms, aquatic worms, fish fry, and other small creatures in the water. They also eat a certain type of algae, called Chlorella, which is what makes hydras green. Chlorella stays alive inside the hydra. Since algae makes its own food. The hydra lets the Chlorella make food for it.
If a hydra needs to move (perhaps it's not getting enough food), it can detach itself and move like an inchworm. They are notoriously well known to kill shrimplets and fish fries in breeding tanks.
Planaria

QUOTE
Planarias are free-living, primarily carnivorous flatworms-with a three-branched digestive cavity and comes in a varieties of colors (White, Rusty Pink and brown). Planarias may eat other living, as well as dead, invertebrates, detritus or decaying organic matter. That is why sometimes even if you stopped feeding for a few days, the planarias do not died from hunger and may even attack freshly moulted shrimps and shrimplets when there is a lack of food. Planaria usually slides on the gravel and tank walls in search of food and or bury themselves in the gravel to hide away from the light.
