Pyrocystis fusiformisProduct Review (submitted on May 23, 2011):
I loved these dinoflagellates. They came on time, in a box with a cold pack. That night, they glowed a brilliant turquoise shade and where still glowing in the morning! I definitely recommend these for everyone. I give it 6 stars out of 5. If i ever need bioluminescent algae again, I am buying here.
