I ordered 2 plants. Both of which came in a nice sealed package with a decent amount of packing material. They were both in rockwool cubes that I took off. They were very healthy plants with an established root mass.
Pros
Provides shelter for bottom-dwelling fish
Cons
They may require specific mineral and nutrient supplements
I received a large specimen in very good condition. I have and will order from them again. There were snails in the rock wool so either soak in Panacur or enjoy the freebie.
