I had two problems with the shrimp:
(1) I ordered 15 peppermint shrimp ... there were (3) bags that were labeled (5) however there were only 3-4 shrimp in each one. I looked at them for 15 minutes so I know the little guys weren't hiding anywhere.
(2) I received 5 cleaner shrimp ... 4 of them were active ... one of them was umm "asleep". Following their acclimation instructions I placed the shrimp together and started the acclimation. It didn't take long for the 4 active cleaner shrimp to clean the sleeping one right up.
That was my fault though ... I should have known better. Maybe he would have come back to life had I put him in a separate bucket.
Make sure you look at their return instructions carefully. They want you to send back the dead items in salt via registered mail.
