Common Goldfish

This goldfish was the first departure from the wild carp ancestor that started it all.

The Common goldfish developed its orange to orange/yellow coloration from selectively bred carp that showed patches of lighter coloration.

These goldfish are suitable and recommended for ponds.  They are hardy fish that can withstand low temperatures, and can grow quite large in the right conditions.

Because of their plain appearance, they aren’t that popular for aquariums.

Goldfish sold as the common variety that exhibit pointed caudal fins are probably just poor specimens of Comet goldfish.    The fin characteristics should be the same as the wild carp, with the caudal fin being short and rounded.

A true to type fish is hard to find these days.

The scale group is always shiny metallic.  Any fish that has nacreous scales will be a crossbred specimen or is a London Shubunkin.

The color change from the drab wild coloration to gold starts quite quickly, at about a month old.  Any fish that haven’t changed color by six months old shouldn’t be used as breeding stock.

These goldfish don’t suffer the digestive problems caused from poor food that can lead to balance problems in the more developed varieties with short round bodies
