Omnivorous, Goldfish are not fussy eaters at all and will consume anything they can fit in their mouth. A healthy diet of goldfish flakes and pellets is ideal in addition to treats such as bloodworm.


Goldfish are peaceful but will eat anything they can swallow, including smaller fish and shrimp. They will also attempt to eat gravel/pebbles, so you will need to keep an eye on them. It has been known for goldfish to get pebbles stuck in their mouth.


Males are more slender than females and may develop white spots on the gill plates.


Goldfish are egg scatterers and like to spawn in plants. For a detailed guide on breeding Goldfish, click here.


Comet Goldfish are one of the most numerous aquarium fish. Unfortunately their requirements are often underestimated and it is a regular sight to see them kept in far too small a tank. Goldfish grow quite large and are active fish so space to grow and swim is vital to keeping them healthy and happy.
