15 mixed colours of Neocaridina shrimp - healthy and beautiful - $25 I breed 5 colours of shrimp in individual naturally scaped aquariums. These "Skittles" shrimp are thriving in my personal aquarium and come in shades of green, red, orange, blue, black, brown etc. Some vibrant colours in the mix too! I continually add various colours from my breeding aquariums to my personal aquarium because I enjoy seeing variety. They're unique and very healthy! Your aquarium needs to be fully cycled before adding shrimp.
