Sorry, I'm not sure of the species name. It's the common pulsing Xenia, brown/tan colored. I've attached a picutre of the type. It's not the one that's in my tank, but it's the same kind.
Saturday is fine. I'm at work in Coeur d'Alene until 4 pm. You can come to my office or I can meet you sometime after 4:30 or so.
