Goldfish are bottom tank inhabitants that provide valuable ecosystem maintenance by keeping the substrate clean. Being omnivorous fish, these bottom dwellers enjoy feeding from an assortment of sources.
Beginner pet owners may become dismayed when their goldfish spends most of its time at the bottom of the aquarium, yet this is part of its natural biotope. To best care for their wellbeing and buoyancy, provide food that sinks; offering floating pellets could cause fish to inhale air which compromises buoyancy and swim bladder capacity.

Food
Goldfish are omnivores that feed on both aquatic plants and small critters in their natural habitat, so aquarium goldfish tend to prefer hanging out at the bottom. It’s not out of boredom; detritus accumulation provides food sources that aquatic creatures eat like goldfish and other aquatic species.
Feed your pet goldfish foods that sink, while avoiding high-fiber options as these will cause bloat. Instead, select foods containing 20-30% protein content for best results.
Goldfish tend to be social fish in nature and should get along well with other types of aquatic life, although this will depend on their temperaments and diet requirements. Look for larger than your goldfish species with similar dietary needs (for instance blue or yellow platies would make great additions); however, you should avoid semi-aggressive barbs like rosy barbs as these might attack and injure fins of the goldfish in your tank.
Breeding
Goldfish are bottom feeders and will readily consume pellets, flakes, plants, small crustaceans and live prey items such as worms. Soaking food for several seconds before feeding it helps it settle to the bottom rather than floating on top of their tank.
Under ideal conditions, you should be able to witness these beautiful fish at work during their natural breeding activity. Males will start chasing females around while pushing her abdomen in an elaborate ritual that can last up to an hour long. Be wary if this behavior appears as it could turn aggressive if she becomes stressed out during mating season.
Goldfish will do well in a community tank as long as their water parameters match up and they’re of comparable size, such as Plecos, Loaches or Guppies occupying similar environments as these goldfish. Plecos, Loaches or Guppies that inhabit similar environments make great additions.
Care
Goldfish, like other omnivorous scavengers in nature, are adaptable creatures that make quick decisions to feed on whatever is available, including plant matter and live prey items. Furthermore, detritus (dead and decaying organic material that sinks to the bottom of their natural biotopes) becomes food.
Pet parents should provide their fish with a varied diet of flakes and pellets to maintain good health, with wetting dry foods before giving it to your fancy goldfish to aid with digestion and avoid buoyancy issues associated with excessively fast gulping of too much food at once and disrupted swim bladders.
An established feeding schedule is key to ensure your fish reaches its full potential and doesn’t overeat, leading to a messy tank and gunky substrate, overfeeding could make your fish susceptible to an ich disease that causes translucent spots on its body and fins; fish suffering from this require isolation as well as medication that can be purchased either locally or online.
Feeding
Goldfish are bottom feeders that feed on both plant matter and live prey items found at the bottom of their natural environments. As aquarium inhabitants, these goldfish also scavenge for food when necessary – making them excellent tank companions!
Goldfish are opportunistic eaters and will consume anything they can fit into their mouths, such as smaller fish or even their own young. Therefore, it’s essential not to overfeed them and provide them with an appropriate diet according to their size.
Feed your goldfish foods that sink rather than float to keep their swim bladder from filling with air during inhalation and digestion. Soak flake food for five minutes prior to feeding it so as to make digestion more efficient, and provide them with plenty of hiding spaces so as not to induce stress, since stressed goldfish secrete an ineffective version of their slime coat, making them susceptible to diseases.
