They have gills to be able to breathe underwater.
Permeable skin, to be waterproof, so they won't sink.
Bright colours to show they are dangerous, so do not approach. (as well as being beautiful)

A Guppy's adaptation is pretty simple to know..... they have the same adaptation all fish have which are: A gill to breath and fins for swiming. Other than that, is nothing else. =]
