all in vain...

All were in vain…all… My three guppy mothers were all died, floating on the surface of water covering with white spots the entire parts of their bodies. I wondered how it could happen. I am now in an effort to check the water and the quantity of anti-chlorine that I supposed to put into and also the black vases I used to place the guppies. Usually when the white spots are seemed to grow on fish, there might be a problem in the supposedly anti-chlorine to be put into a pail of water. Three drops should be enough that I usually do every time I make some water addition when the existing water faces a deficiency of its level but this time it makes difference...
