I said I would reply once I received the package so here it is.
I let the bags float on top for awhile slowing adding water. I followed the directions that came with the package. I was alittle nervous when I put the mushroom rocks into my tank because they sure didn't look like much. I arranged the rocks where they fit best. Left to go take a final exam and when I came back home I was very pleased.
I received one purple, one red, one green with reddish spots, one light green, and one kind of pinkish. All had opened up and look beautiful. Most had more then 7 mushrooms on each rock. Good package. : )
