I don't think the unusually colored fish are hybrids of Koi and goldfish because these fish belong to different technical scientific named genus and individuals from different genera and typically will not successfully interbreed. Technically it gets into number of chromosomes for egg and sperm to combine and form a developing egg. Chromosome number has to be very close in number and similar such as in donkey and horse for the chromosomes to match and for an egg to form and cells to continue division.
