Pond Boss Forums INTRO Questions & Observations Identify the fish.....may have a problem

Thanks. The biggest difference that should be discernable in all fish, irregardless of size is the anal fin ray count. 12 in CNBG and 11 in BG.

So, I'm just guessing here but if the fish is a hybrid, that anal ray fin count would still apply.

Hmmmmmmmmmm................. That might mean counting and splitting any "CNBG" into two groups to test their cold water survivability depending on the anal fin ray count.
