Everything went perfectly. The package was waiting for me, as expected. All of the Berghia were visible and active. After the drip acclimation, they are now in my tank. I watched as they crawled, from where I placed them, into the rock work.
They little dudes made it here yesterday, and were in very good shape. They are now in my tank, and hopefully hidden in the rock work, eating and getting really fat. Thanks for all the details and quick shipment.
