My cherry shrimp were doing well for the last 3 months. All of a sudden the adults started dying - their tails having these dark and white blotches where they used to have red. Now one of my younger shirimp is showing same issue on the tail. Attached is a picture of said shrimp.
I was reading on shrimpcorner.co.uk website blog about conditions affecting shrimp and my problem sounds like a chitinolytic or bacterial disease but the picture examples do not look like what my shrimp have. Anyone seen this before?
