My Neocaridina "Skittles" shrimp come in mixed colours - healthy and still very pretty. 10/$20 or 15/$25 I breed 5 colours of shrimp in individual naturally scaped aquariums. "Skittles" shrimp are thriving in my personal aquariums and come in shades of green, red, orange, blue, black, brown etc. Some vibrant colours in the mix too! I continually add colours from my 5 breeding aquariums to my personal community aquariums - they're great little cleaners. Your aquarium needs to be fully cycled before adding shrimp.
