I wasn't aware that goldfish occurred in the wild,they certainly don't have any kind of defense system to protect them against any predators. If there is a fish that eats them then the condition of their scales won't make much of a difference.
Nice fish in the body but not enough finnage for my own liking. He looks disproportional.
fishhead0103666 scales swirling like this creates drag for the fish. Makes it harder for them to swim and these short bodies fish are already not the best at swimming. Scales dont just protect a fish. They are designed by evolution to reduce drag and help the animal cut thru the water
