Hi bikerchick... due to the inbreeding of guppies over years genetic defects have developed. I too have had this on some of my guppies, it is almost like they are paralysed. There is nothing you can do she will soon lose her appetite and then sadly die

Sorry there is not better news for you, i once lost an almost entire clutch of 40 fry to this At least it is not contagious.
