Why do they lose their leg?
I Have a few shrimps who have lost a leg ore two.
What is wrong?

Leggs and antennas can disappear by violent accident or by bacterial diseases.

How do I get rid of bacterial diseases?

[imke_j]

You must lower bacterial concentration in the water and provide better water quality. Here is what I experienced in summer 2009 with my tiger shrimps (copied the article from my blog):

Shrimp diseases are yet unexplored in their variety and no one likes to confess that his/her shrimp are or have been ill. But livestock breeding isn’t easy at all and that’s why I want t o talk about bacterial infections of shrimp now. I have had problems with my Blue Tiger Shrimp lately: Some of them where turning kind of white in the body inside and the usual colouration fades. The legs where apparently white like Golden Bee legs and some of them even lost antenna and other extremeties. In a later phase, shrimp are inactive and may ’stagger’ through the water. This shrimp mostly die later on.
Growing populations of harmful bacteria called Aeromonas sobria was probably the cause (see O. Breitenstein for aquanet.tv (http://www.aquanet.de/content/fachbeitrag/45d049f1-29be-48a6-9697-c82b688c41cc)). Due to higher water temperatures this bacteria can spread disproportionately high. Overcrowded tank with lots of organic waste pander the disease. If the immune system is weakened other parasites or fungus can penetrate more easiliy.
But how to get rid of this prob? Advices:


daily water changes with 80% minimum (not less!) for at least 2 weeks. This lowers the quantity of bacteria.
lower the temperature of the water if possible
clean the tank and gravel
add O2 and garantuee a good water filtration
feed less
remove ill or dead shrimp asap

Be careful with pharmaceuticals because this particuliar harmful bacteria might be resistent to antibiotica. In my special case, I supported the recovery with JBL Furanol (http://jbl.de/uk/aqua/uk_krankbild.html): 1 tablet for a 20L tank, added for 4 days. I did a 80% water cange then and added 1 tablett again for 3 days. I than filtered with carbon for one week to get rid of the pharmaceutical.

Tank you so very mutch.
I will start all that tomorrow. :)

I also avoid to use antibiotica.
Mosura Shrimps Tonic helps beside wc, cleaning and other methods.

I got some Mosura Shrimp Tonic today. :)
Thanks for the tips.
