If you are not into selling your fish, I wouldnt worry about the 'hybrid' of your rainbows.. They are gorgeous and unique!

Could be a mix of a Red Salmon (glossolepis incisus) or a Lake Tebera (melanotaenia herbertaxelrodi)
Since your head is spinning anyway, here is another rainbow name to look up. Its called: Parkinson's Rainbow. Melanotaenia parkinsoni. A south Eastern Papua, New Guinea.
Description has it:
Parkinson's rainbowfish is an unusually colored and patterned fish in which a sparkling bluish base color is liberally mottled in yellow, gold and orange in the posterior half of the body.The same yellow, gold and orange extends into the unpaired fins. A red form is also avilable.(quoted from my fish bible: 500 freshwater aquarium fish by Greg Jennings.)
Even if you never find out exactly what type it is... you still have some great looking Rainbows there.
