Molly? Do you mean moor?
GOldfish change color. Black is a very unstable color and usually goes gold. Gold can sometimes go silver.
It's mostly genetics, so don't worry, they're fine! :)

You mean Black Moor yes? The black colour is actually quite unstable genetically and will often revert to the gold/bronze colour.
Goldfish will often turn to silver, there's a dozen reasons banded about as to why it happens, being kept in the dark with not enough UV, diet, surroundings, water quality, stress and old age are all reasons.
a molly is not a goldfish... I think me mean black moor. and they will turn gold its very normal... as for your fantail... same thing as your moor... its totally normal.
