    Default Why does a shrimp turn red?

    Look at left shrimp on the picture:

    I lost several orange eyed blue tigers in this tank. They all are turn red in a chest area before they gone.
    I can't tell whether it's from inside their digestive system or it's just a skin.

    What is wrong with my food, water or hardness. What do you think?

    It looks to me to be an infection, bacterial or fungal. I would quarantine the infected specimens.

    However, I have no further advice to offer. There are far more informed keepers here who may have direct experience with Tigers. We can't get them in Australia.

    Good luck

    I just found several dead blue pearl shrimps. Some of them have similar red stomach area.
    There were fine just yesterday.

    What kind of things can make them dead and red from the inside?

    As stated, this is an infection. Quarantine immediately!

    These infections are passed on by eating. When one shrimp dies, the others will quickly eat it and become infected, also.

    Thank you, it makes sense.

    But how can I 'cure' shrimps from it?
    Last time I had that thing I was changing lots of water everyday and in a week it gone. But I lost several dozens of shrimps. They are usually adults.

    Quarantine and water changes. Medications prove difficult, expensive & often lethal to shrimp.

    Ok, I see. Thank you!

    In fact, I can't guarantee all my colony.
    I will try to separate shrimps into two groups and will promptly remove dead shrimps. I have been seeing a dead shrimp each several hours now.

    Igor,

    Isolating some "clean" shrimp to act as "bank" in case you are unable to stop the spread of the infection, is a very good idea.

    If you started with a large colony, you will probably find that some may survive infection. These will then be resistant.
