Male guppy attmpting baby goldfish murder! July 2, 2007 at 8:23 pm #11545 CrazedpufferParticipant Yes I have fancy Guppies also the same size as my fan tail. It worked for a little more then a week before they got eaten. Also all the fish in the tank will eat babies. Do you have a seperate tank for the babies too?
