What Comet Goldfish look like

Comet Goldfish are long-bodied goldfish selected for speed and a long deeply forked caudal fin. They are streamlined, single-tailed, and best considered pond or very large aquarium fish.

Behavior & temperament

Comets are active, fast, social fish that outcompete delicate fancy goldfish. They need strong filtration, open swimming room, and cool stable water. They are egg scatterers.

Diet & feeding

Comet Goldfish are omnivorous grazers. Feed quality goldfish pellets or gel food, blanched greens, duckweed, daphnia, brine shrimp, and occasional bloodworms. Feed modestly enough that water quality stays stable.

Behind the name

Comet refers to the long flowing tail trailing behind the fish.

Plan your tank

Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
