The shrimp arrived alive and in good condition. However, my aquatic skills are lacking as one week later, there are only 8 survivors. I tried to acclimate them slowly after arrival and for a day or so I thought it was successful, but alas no. Yes I had adequate and different food offerings, temp was right, live plants, established and stable 10 gallon tank. Thanks for your shrimp. I am studying, but I am an experienced fish guy. Just no so much shrimp I guess.
