Goldfish typically won’t bite each other, but it can sometimes happen when there is a territorial dispute or when a goldfish is feeling threatened or stressed. If the tank is overcrowded, goldfish may become more aggressive toward each other and bite each other.
It is also important to consider the size of the tank, as goldfish should never be kept in tanks that are too small for their size. Goldfish that do not have enough space to swim and hide can become stressed, and may be more likely to show aggressive behavior.
Additionally, ensuring that the tank is properly cycled and has the appropriate filtration, as well as that the water quality is well maintained, can help to prevent goldfish from becoming overly aggressive and biting each other.

Why is one goldfish bullying the other?
It is difficult to know the exact reason why one goldfish may be bullying the other. In some cases, bullying can establish a pecking order, particularly in smaller aquariums, where there is limited space.
Overcrowded goldfish tanks can lead to increased levels of aggression and competition for food, as well as space to swim. When this occurs, one or more goldfish may try to establish themselves as dominant and may start to assert their authority by bullying weaker or less dominant fish.
In some cases, it may also be due to a genetic predisposed behavior – some goldfish are just naturally more aggressive or competitive than others. It’s important to keep an eye on the fish to identify any bullying behavior, which normally involves chasing, chasing, nipping and/or fin-flaring.
If the behavior persists, it is recommended that the tank be reorganized to give the bullied fish more places to hide, if possible. It may also be a good idea to add more plants and decorations to the tank, as well as to monitor the tank’s population to ensure that it does not become overcrowded.
How do I know if my goldfish are mating or fighting?
In order to determine whether your goldfish are mating or fighting, there are a few signs to look out for. First, look out for any physical contact between your goldfish. If you notice one of your goldfish chasing and chasing the other, they are likely fighting.
Male goldfish in particular often nip at the fins of other fish as part of their aggressive behavior. On the other hand, if you see two goldfish swimming side by side and rubbing against each other’s bodies, they may be mating.
Additionally, during mating, some goldfish may circle around each other in a courtship dance, displaying their fins and swimming around in figure eights. Finally, in a group of goldfish, take a special look at one aggressive fish.
Males that are interested in mating may become more aggressive in a bid to dominate the other fish, so this could be another sign of mating.
Why are 2 of my goldfish chasing each other?
In the wild, goldfish prefer to live in groups but in a confined tank they cannot express their natural behavior. Chasing one another is an instinctive behavior that may indicate that the fish are trying to establish a hierarchy amongst themselves.
The chasing may also be a form of courtship and mating behavior, so if two of your fish are the same gender, it could be a sign that they are trying to reproduce. It’s also possible that the chasing is a sign of stress, such as when a goldfish is overcrowded or needs more space.
It could mean that your tank is too small and you need to upgrade to a larger one. Furthermore, insufficient maintenance of the tank could be causing the fish to feel that the tank is unsafe and engage in this behavior.
Lastly, make sure that your tank is properly oxygenated, as goldfish require a high level of oxygen for their wellbeing. If the oxygen level is low, the fish may be struggling to breathe and become overly active in the tank.
How can you tell if a goldfish is a boy or a girl?
In order to visually determine whether a goldfish is a boy or a girl, there are a few physical characteristics to look for. For male goldfish, they usually have a thicker body than females, along with a more pronounced “ruffling” of the gill cover.
Furthermore, they usually have a small, whitish patch on the underside of the gill cover, called “breeding tubercles”. These tubercles will be more pronounced during the breeding season. Additionally, the males have much more elongated, pointed pectoral fins than females.
For female goldfish, a surefire way of determining gender is to look for eggs inside the body cavity near the vent (a small hole near the base of the tail). During spawning season, it is common for goldfish to produce eggs, and this will be most evident in females.
Finally, female goldfish are often heavier or more round in shape compared to male goldfish. While these characteristics can be useful clues for assessing the gender of your goldfish, it is not always accurate, as some males may have large and round bodies and females may have a slender body shape.
Therefore, the best way to guarantee that you identify the gender of your goldfish is to take it to a veterinarian who can provide you with a definitive verification.
Why did my goldfish eat my other goldfish?
It’s important to note that goldfish have been known to eat smaller fish, so it’s entirely possible that the act was completely natural. Additionally, goldfish can become quite territorial, especially if they haven’t been properly acclimated to their environment.
If they’ve been around each other too long, they may fight for dominance or territory. It’s also possible that your goldfish simply wasn’t getting enough food, prompting it to become more aggressive to other fish in an attempt to secure a meal.
On the other hand, there may be a larger issue at play that has caused your goldfish to become aggressive or driven to eat another one. Poor water quality, nutrient deficiencies, and overcrowding can all spur aggression in goldfish.
It’s important to ensure that your tank is big enough for your fish, that the water is clean, and that you’re feeding them a high-quality diet. If that doesn’t seem to be the issue, it is best to speak with a veterinarian in order to determine the underlying issue and take the best action for your other fish.
Can I put a new goldfish in with my old one?
Yes, you can put a new goldfish in with your old one, but it is best to do it slowly and carefully. To ensure the safety of both fish, start by introducing the new goldfish to the tank in a separate container for about an hour at a time.
This will allow them to get used to one another, and it will also prevent any aggression from occurring. After adding the goldfish to the main tank, monitor the behavior of the fish for a few days to ensure that they are getting along without any problems.
Make sure that both fish have enough space to swim, and that they each have access to food. In some cases, you may want to provide additional plants, caves, or other hiding places in the tank to provide extra security and to promote peaceful interaction.
Additionally, make sure that the water parameters in the tank are appropriate for both fish. If both of your fish are healthy and seem to be getting along well, they should be able to happily coexist together in the same tank.
Are goldfish toxic to other fish?
Generally speaking, goldfish are not toxic to other fish. Goldfish can be a peaceful species that can often get along in tanks with other types of fish. That said, they are omnivores and can become territorial, so they should not be kept with very small or delicate species.
Additionally, goldfish produce a lot of waste that can be toxic to some species in large quantities, so it’s important to perform regular water changes and make sure the tank is adequately filtered.
What are goldfish teeth called?
Goldfish don’t actually have teeth in the traditional sense. However, they do have “pharyngeal teeth,” which are located in their pharyngeal (throat) region, and which they use to crush food. These special teeth are set in a stone-like material called “dentine,” which is found surrounding the base of the scales.
The pharyngeal teeth are arranged in a unique curved pattern so that the fish can better grind up bits of food. This arrangement is similar to the way modern-day mammals have teeth in our mouths.
What kind of teeth do goldfish have?
Goldfish have pharyngeal teeth, which are located in their throats. These teeth are flattened, and curved towards the rear of the throat. They are very small, and usually measure 1-2 millimeters in length.
The pharyngeal teeth are responsible for grinding up food, and they do not grow or regenerate like regular teeth. Goldfish also have regular teeth located on the upper and lower parts of their jaws. These teeth, like those of other fish, are quite sharp and are used to capture and hold prey.
Though they are easy to see and feel, they are much smaller than the visible teeth on a human mouth, measuring just millimeters in length.
Do goldfish have canine teeth?
No, goldfish do not have canine teeth. Goldfish have a basic type of tooth known as “pharyngeal teeth”. These pharyngeal teeth are found in the back of the goldfish’s throat. They work like a rasp to help the goldfish grind down their food so they can swallow it easier and digest it more efficiently.
These teeth are very different from the canine teeth found on humans and mammals. Canine teeth, also known as “fangs”, have evolved for defensive purposes and to help tear apart animals and raw meat.
Goldfish do not need these canine teeth since they are herbivores and only feed on algae, insect larvae, and other plant matter.
What are pharyngeal teeth in fish?
Pharyngeal teeth, also known as pharyngeal dentition, are teeth that are located in the throat area of fish. This type of dentition consists of conical, bicuspid, and molar-like teeth that are organized into one to three rows of teeth located near the gills.
These teeth are usually used for food-processing and feeding, although their exact function may depend on the species of fish. Pharyngeal teeth have been found in both fresh and salt water fish, but they are more commonly found in freshwater species.
The arrangement of these teeth can be highly diverse, depending on factors such as the size and anatomy of the species. Generally, the larger the fish, the higher the number of teeth in its pharyngeal dentition.
Do comet goldfish recognize their owners?
Comet goldfish, like many other fish species, have the capacity to recognize their owners. Per research conducted by the University of Oxford, goldfish can recognize individual people by their faces.
Additionally, the study found that goldfish are able to remember the faces of those they encounter over time. Studies have also shown that goldfish have the capacity to develop behavioral responses to their owners, as well as objects, such as food, being presented.
For example, a goldfish may recognize and respond to their owner reaching into the tank, or a container with food. While these species may not show warmth and affection like some other pets, goldfish can recognize and respond to their owners, as well as objects and stimuli, in meaningful ways.
Are comet goldfish friendly?
Yes, comet goldfish are generally considered to be friendly. They are a type of fancy goldfish, which means they tend to be hardy, easy to care for, and relatively friendly. Goldfish can become quite social and recognize the person that cares for them, even following them around the tank.
They are a highly intelligent fish species and can remember when it’s feeding time, sometimes even responding to their owners voice. They also make for fun companions, as they interact with one another and can learn how to navigate aquariums.
Comet goldfish are a particularly good choice for more novice fish-keepers, as they are hardy and can even tolerate the changing water conditions of first time tanks.
Have goldfish got teeth?
Yes, goldfish have teeth, although they don’t look like the teeth humans have. Their teeth are bristles that are located on the edges of their “tongue” or the roof of their mouth, which is used for grinding food before it is swallowed.
Goldfish also have a second set of teeth located on the outside of their mouths called pharyngeal teeth. These teeth are used mainly for catching and holding prey. It is also possible for goldfish to develop tusk-like teeth, caused by an abnormal growth that may be a sign of an underlying health issue.
