So my little rainbow fish fry from Catfish Creek are growing up nicely, they certainly settled in well and took readily to all available fish foods.

The main mystery with them is WHAT species or sub species of Rainbow fish are they???

This next one is the only one of the 6 who is developing the green flash up its side ( sorry this is the only non-blurry picture of it)

Could this mean its another type of rainbow since it doesnt seem to be developing the black fin edges only the green and possibly yellow side flashes (the yellow didnt show up in the picture)

And finally

"What you lookin at?"

In the above picture you can make out the yellow that is in his fins surrounded by the black.
