This is a Common Goldfish.

Their closest relative is the Prussian Carp, the only difference is their color.

Commons come in a variety of colors including red, white, orange/gold, or black and yellow.

Be careful about what other types of fish you mix with Commons and Comets, they will eat anything they can fit in their mouth!

This is a Bubble Eye Goldfish.

They have upward pointing eyes with 2 large fluid filled sacs underneath.

It wouldn't be a good idea to tank any aggressive, fast fish with these guys due to the delicate bags under their eyes.

This is a Fantail Goldfish.

They have an egg-shaped body with a high dorsal fin and a long quadruple tail fin that spreads out and resembles a fan.

These fish are classified as "fancy" like the Bubble and Moors. They're not a basic shape like the Comets and Commons.

This is a Panda Moor Goldfish.

This is a Black Moor Goldfish.

It, like the Panda Moors, have telescopic eyes and should be tanked the same.
