It took two weeks to get the 10 shrimp I ordered, which was my fault, I ordered in a hurry and didnt see that they only ship on Mondays and Tuesdays. I wasnt home when they arrived, but my house sitter brought them in and got them into their tank. They must have thrown extras in there because I lost at least 4 within 24 hours (I did my best explaining how to acclimate, I was expecting worse honestly), I still have 8 alive somehow lol. So thats wonderful! I still gave 5 stars though.
