I have been ordering Copepods for many years and I never notice any reaction from my fish or corals when I bought from other places not so buying from Pod Your Reef! The copepods were alive and well! You could even see some swimming around in the tank my mushroom corals went crazy! Highly recommend getting your copepods from here!
