Types
-
The types of goldfish include flat-body and egg-shaped, such as fancy goldfish. Egg-shaped goldfish cannot live with flat-body goldfish.
Warnings
-
Egg-shaped goldfish are slow swimmers, and many fancies have trouble seeing. Flat-body goldfish will consume all the food before the egg-shaped ones realize you dropped food in the aquarium.
Identification
-
Egg-shaped or fancy goldfish look round like eggs and have decorative, long fins. Some fancies have bulbous heads or eyes, like the celestial bubble-eye and the black moor. Flat-body goldfish have slim, streamlined bodies and swim quickly. They include the common goldfish and comets.
Environment
-
All types of goldfish can survive in an unheated, indoor aquarium.
Temperament
-
All goldfish are social. However, flat-body goldfish may bully the egg-shaped fancies if the aquarium is too small and the fish are competing for space and food.
