I recently bought eight fish sold as Forktail Rainbows. In all of my
meanderings through Rainbow pictures and discussion on the web, I have
never seen them referenced.
Here goes the description. First off, they are not the typical
rainbow deep body, instead shallower like a Killie or guppy. The
"Forktail" moniker derives from a tail edged top and bottom in bright
yellow, grey or black in the middle. I think the most unusual feature is
the set of pectoral fins that actually extend upwards to the top of the
fish, again edged in yellow as are all of the fins. The body is a shiny
silver and the eyes are blue.
Any ideas as to the true identity of these little guys and where I
might see a picture? Also, what would be the adult breeding size? Any
help greatly appreciated.
