I got two new Tillandsia plants to put in my tank. They both are Tillandsia funkiana (might also be spelled funckiana). I plant to mount them on a piece of grapevine and hang a wire about the bigger end of the grapevine, forming a hook on the other end to hang on the edge of the terrarium top. I figure this is also the way I'm going hanging another grapevine piece with airplants in the near future. Each of them is four to six inches already in length.
