The mystery of my missing platy

Ok see my sig I believe that the fish I have in my 36g tank are pretty peaceful. Here is my story I have a calico platy that has been missing from my tank the last few days. I saw her in the tank on Thurs and now have no idea where she is. I looked under the cave and behind my shipwreck bubbler. I have not seen her body floating on the top or laying on the bottom so I don't know where she is. She doesn't come out to feed when I feed the fish. I am really upset could it be possible that one of the fish ate her my other platies are fine. I suppose if she is dead I will find her when I clean the tank. I am upset because she was one of my first platies. any ideas what could have happenned to her. I am stumped.:help:

Awwwwwww man that sucks she was one of my fav platies I thought she was fine but maybe she got sick who knows but I had her for months poor thing if she is dead what a way to go

No spikes in parameters no she is not in the shipwreck I haven't seen her since that Thurs. I think as sad as it is she is gone very mysterious though. She was fine not sure what happenned or how she died and from what and that is upsetting to me. I did get another female platy to keep the other male company she is bigger than my other platy was and is doing well. My other platy was so pretty am very sad she is gone.
