I bought a fantail about 2 months ago because of its coloring, nice
orange with a great black stripe on it's back, black tail and touches of
gold/yellow on it's belly. I noticed 3 days ago that the black is
alomost completely gone form it's back and very faded in it's tail. Can
anyone tell me why. None of the other 5 fantails in the tank have
changed color and they are all about the same size, approximateyt 1 -
1.5 inches long.
