Probably the same exact zoa, but given the different variables such as water quality and lighting between the 2 vendors system they probably look different. My son and I have many of the same zoas in our tanks, but becuase I run LEDs and he has T5s they look quite different. Even if I take zoas fomr his tank and put them in mine they still look slightly different until they have re acclimated to my lighting.
Ive ran this experiment many times thinking one of us had a cool morph or something and it always end ups the same once they are under the same lights and have had proper time to acclimate.
