Hugo Mulertt created the Comet Goldfish during the 1800s, and since then they have taken aquarium hobby by storm. Descending from wild Prussian Carps, these aquatic beauties thrive when kept in large tanks with plenty of plant-based food available.
Goldfish will eat regular goldfish flakes, but for optimal performance they require a diet tailored specifically to their dietary requirements.

Substrate
Comet goldfish are adept scavengers that will search through substrate and plant roots for any scraps of food that have fallen to them, as well as taking advantage of any opportunities presented within an aquarium to consume algae from surfaces within it.
As these fish have fast metabolisms and diets, they produce large quantities of waste. Therefore, they require a large tank with an oversized filter in order to keep ammonia and nitrite levels under control.
Regular vacuuming/siphoning and frequent water changes will help maintain optimal water quality.
Breeding Comet goldfish should ideally take place in an aquarium environment, where once females are ready to spawn their eggs can be removed and placed in separate tanks. Male comet goldfish will develop white tubercles on their gill covers and pectoral fins and protruding anal vents as signs that they are ready for mating; females on the other hand have fat bellies with less protruding pectoral fins indicating readiness to breed.
Plants
Comet goldfish are popular as petfish due to their easy care requirements and wide array of colors. Omnivorous in nature, comets eat everything from plants and algae to insects, snails, crustaceans and water plants; feedings may include flake foods, pellets or live food such as daphnia brine shrimp or tubifex worms.
Comet goldfish thrive best when housed in a large aquarium or outdoor pond, as these active creatures require plenty of room to swim and grow. When kept in smaller environments, stress levels quickly rise, increasing risk for disease development.
An ideal Comet goldfish should exhibit glossy scales and vibrant colors, without signs of fungus, flukes or bacteria. Keep an eye out for sores or reddened areas on its body, gills or fins which could indicate infections like Ich, Swim Bladder Disease (SBD), Fin Rot or Stress Rot. These conditions often arise due to poor water quality or contaminated live food sources.
Food
Comet goldfish are omnivorous and require a variety of foods for proper care and color enhancement. High-quality flake food formulated to enrich their colors may be especially beneficial. In addition, Comets enjoy eating live worms, daphnia and pond sticks!
These fish have long fins that are susceptible to fin rot if the water quality falls short, as well as developing ich and swim bladder disease if kept in poor conditions.
These vibrant fish make for great aquarium viewing as they dart around their tank with ease. Their intelligence allows them to recognize their owners, while being relatively easy to care for overall. Unfortunately, however, their size largely determines their size; you will require a large aquarium or pond in which to house them successfully and keep them happy. Environment plays an integral part in their size development, and given enough room they may become quite large fish indeed! They may become aggressive when hungry and attack smaller tank mates which makes this fish quite hazardous in your care!
Water
Comet goldfish add a colorful splash to any aquarium and are generally easy to care for. As they can reach larger sizes, however, at least a 55 gallon tank should be allocated as their tank, as these fish tend not to be suitable for beginners.
Cobia are hardy fish that thrive in less-than-ideal water conditions, making them an excellent choice for outdoor ponds with other fish like koi. While they don’t mind strong water flow, make sure there is ample room to swim freely before adding sharp decorations that could potentially snag their long fins and threaten their safety.
As a general guideline, comet goldfish should be fed two to three times each day. Omnivorous in nature, these aquatic inhabitants require flake foods and pellets as staples in their diet; you can supplement that with frozen bloodworms, daphnia, and brine shrimp as desired. They also consume algae and plant matter so make sure there are plenty of green plants present.
