Goldfish are known to be opportunistic feeders and will eat just about anything they can fit in their mouth, including snails.
Some snails, such as nerites, can live harmoniously alongside goldfish in an aquarium and help to keep it clean; other snails such as ramshorn snails feature beautiful colors while contributing to keeping the tank free of algae growth.

Size
Goldfish can reach great size under ideal conditions; some have even reached 10 inches long!
Goldfish released into the wild can wreak havoc on natural ecosystems. Their voracious appetite consumes snails, amphibian eggs, fish larvae and young, aquatic plants and aquatic creatures such as snails. Furthermore, their presence alters water chemistry by stirring up mud and decreasing sunlight penetration into aquatic systems.
Researchers from Murdoch University conducted research into the effects of goldfish in Tasmanian waterway known as Vasse. Over one year, they tracked these fish over time and observed them outcompeting native species for food and habitat, disrupting oxygen levels by foraging shallow waters where oxygen levels are low; disrupting an ecosystem by foraging for oxygen-depleted waters due to their long distance swimming capabilities and high protein intake (cosmos). Goldfish thrive in such poor environments because their high protein intake allows them to outcompete other local species for food sources (cosmos). Furthermore, social creatures that enjoy having company among their own kind – even during changes or when water changes occur!
Environment
Snails can help maintain a healthy tank by sucking up organic debris from the gravel and eating uneaten food that rots in the tank, thereby decreasing algae bloom. Unfortunately, snails can overbreed and damage aquarium plants without proper management.
Before adding snails or any other aquatic creatures to your goldfish tank, it is wise to quarantine them to protect against diseases they might carry that could affect them. Simply place the snail in a jar containing stems of fast-growing plants with enough water covering their bodies – this should suffice.
Larger snails can serve as an effective deterrent against goldfish, as they’re less likely to be eaten by them. Nerite snails are ideal as they have thick shells and reach an inch in diameter, while Ramshorn snails come with vibrant hues for added visual stimulation in your aquarium.
Behavior
Goldfish fish often interact with humans when food is involved. They recognize their owners by the faces in the tank, swimming to them whenever food is present and mouthing at the surface to ask them for it. Goldfish may even learn to associate specific voices or names with meals and respond when seen or called.
Goldfish tend to be peaceful creatures when kept in captivity and don’t tend to fight or bully each other, however if their environment changes (change in water quality), or other sources are overwhelming them they may become more aggressive and start chasing or fin nipping each other.
Goldfish may make great pets, but their wild presence can be detrimental. Their voracious appetites and tolerance of cold waters have the ability to negatively impact native biodiversity while their bold behavior of “sucking and spitting” during foraging can uproot aquatic vegetation, reduce clarity in water bodies, release nutrients that promote algae growth.
Food
Goldfish are voracious omnivores that will consume anything they can get their fins on; however, this doesn’t mean that you should feed them things that may not be good for them; in fact, overfeeding is one of the primary causes of fish deaths, so take care to not give too much food at once!
Goldfish should only be fed what it can consume within two minutes – this serves as a reasonable guideline, though you should still try and vary their diet to avoid overfeeding them.
Some people enjoy offering their goldfish an occasional treat of boiled vegetables such as broccoli or zucchini as snacks in their aquarium. Blanching carrots or other fruits to provide additional variety is another popular practice – just make sure that any produce that may cause irritation has been washed before giving it to your fish!
