Caridinides wilkinsi 'Calman' aka CWC.
Temp 22-28 deg cel
They thrive on decaying leaves, algae and other detritus materials in ponds/tanks , great little workers/cleaners.
They will breed in freshwater, it doesn't require salt/brackish water to breed.
Similar to chameleon shrimp, colour will change depending on their environment.
