Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations RESxGSF hybrid

This fish has the appearance of a pure RES but lacking much of the red/orange coloration on the opercular tab. It does have a narrow orange band but it is small and is such that leads me to believe it might be a RESxBG or RESxCNBG hybrid.

Any opinions on the pedigree?
