I am honestly not sure how long until she drops! This is the first tinme I have seen this happen with her or any of my fish.. none of teh others are white!! Maybe I have been feeding her too much!! I have been feeding her three times a day. Same as the othes, but the others dont get like that. She doesnt move around a whole lot... but when she does she is pretty active. Right now she is sitting at the top of her tank. I tried looking on the pics on here to tell how long until she drops.. but I jsut cant tell.
