I received my 33 shrimp December 1, 2017! It’s hard to believe that I’ve already had them for two years. There was one shrimp fatality a couple weeks after I received them but I haven’t noticed any since. The tank is 5 gallons and it has only had 1 small partial water change about a month ago when I added too much spirulina by accident. I have only fed the shrimp about a dozen times or so over the past two years. I saw the first berried shrimp July 2019, after 1 year, 7 months, and 19 days. This resulted in 15 floaters and in September we had another batch of 35 floaters. Currently I have one berried female with lots of eggs, and another with only 3. I have thoroughly enjoyed my experience with these guys and get great pleasure when a new berried shrimp is spotted or a bunch of floaters appear. By my calculations if we haven’t lost any of the shrimp we are up to 82 and still only see about twenty at any time. Still lots of room to grow.
