Hello, I have a friend who says that after her female fancy guppies give birth they just die the next day. She says that her water levels are stable and they are the same that she has always had them at. She says that the Fry seem fine and go into the breeding grass she has until they grow larger. Another friend of her says she is also having the same problems with her female guppies. They are healthy one day and then after giving birth they die for no reason. Are they doing something wrong, is there something they are supposed to be doing that they are not? I told her I would ask you guys and see if there was any ideas as to the problms. Thanks
