Awesome looking shrimp.
Dwarf Crayfish, not a shrimp. Which is what makes them much more amazing. A crayfish that is fish and shrimp friendly! I forgot to mention, plant friendly too! Truly an amazing sp. There are other dwarf crays that behave similar to these but I believe these dwarf orange crays are the one that catches people's eyes the most.
CPO stands for Cambarellus patzcuarensis 'Orange'
This is just a color variant of the original Cambarellus patzcuarensis. Long name, hence why most people just abbreviate with "CPO" for short.
These are generally sold in groups or in pairs.
Pairs go for about 50-60 dollars each.
