Once I get more tigger copepods in stock, I will start a new thread with a link to a video via photobucket. I just split the mother culture today, but I can film it as a demo. How many, I can not say. Estimate, around 500 good sized adults with many younger copepods. I recently bought a tisbe culture from aqua culture nursery farm, but due to the temperature fluctuations I received the package DOA, along with the replacement. I am waiting for winter to kick in before I place another order. Cold packs are just not cutting it in 100 degree weather.
