Dream Blue Velvet Shrimp turning Brown
Well, like the title says. I've been keeping some Dream Blue Velvets in a planted 10 gallon tank. Couldn't help but notice 1 or 2 shrimp turning brown. Fearing an infection I isolated said shrimp, not expecting them to last more than a few days. Fast forward to several months later, and they are both still brown but doing fine. It was time last week one of the browning blue Velvets finally passed over night, and my second one is doing just fine. I have included 2 photos of the second browned shrimp before I removed it from my 10 gallon. I just want to know if this is some sort of genetics related change causing the brown to appear over time, or if it is some sort of bacterial infection.
