I initially ordered a pair of the blue platinum guppies and bloody Mary shrimp. I changed my order and their customer service was still great. The shrimp I ordered got delayed in shipping twice and the seller reached out ahead of time to assure me that they were ready to replace if anything happened. The shrimp surprisingly showed up all alive even after a week in shipping! I dosed with prime and acclimated slowly. The shrimp are all alive and colouring up quite nicely. I recommend ordering from this seller. They are currently having a free shipping promotion!
