ok my adult guppies from stores seem to die after a week or two, however i have babies that are around 2 maybe 3 months and are ok... does this mean they wont die on me? btw they are in the same tanks the adults were in... becuase i want to move some from a ten gallon to my forty gallon to breed danios in the ten gallon... if everything is the same as far as water perimeters go will the transfer be an easy one? what can i do to make it less stressful?
