Guppy Fry

Can Guppy fry be kept in Glass Bowls.

Fry are very sensitive to fluctuations in temperature and water quality. I wouldn't keep them in a bowl - if you need to separate them from parents and don't have a separate tank, I'd suggest either a tank divider (if the holes are small enough that they won't fit through) or a net breeder trap.
If you don't mind a few being eaten, housing the fish in a heavily planted tank will allow some of the fry to escape and survive to adulthood.
