Everything Was Perfect

I ordered the duckweed along with 15 caridina shrimp and multiple different snails. Every single animal arrived alive and healthy and all plants are thriving a week later.

Package also arrived very quickly. 23 hours from Ohio to California.

Wonderful healthy plants! Arrived gorgeous.

Couldn't ask for a better delivery. The Spirodela is healthy and beautiful. Everything was packed well and insulated for protection against the weather. All of the plants are doing well in their new home.
