Do Convict Cichlids Have Teeth: Are Their Bites Painful?

Cichlids are among the more popular fish species in the aquarium trade today. These fish are known for their vibrant colors and exciting behaviors. In this article, we’ll look at what makes cichlids such a popular choice for aquariums and what kinds of care they need to thrive.

Yes, some cichlids do have teeth. This is primarily seen in the genus Cichlasoma. The front two-thirds of their mouth (anterior region) is filled with sharp, pointed teeth used to rip food from the tank or other object. The rest of their mouth is not as specialized and instead has a wide range of uses, such as sucking up food or water droplets and grasping prey.

Do All Types of Cichlids have Teeth?

There is some debate as to whether all types of cichlids have teeth. While some experts contend that all cichlids have teeth, other experts believe that only certain cichlids, such as the Mbuna and Haplochromis species, may have tooth-like structures on their upper jaw. In any event, cichlids possess some form of sharp teeth – whatever their state – and they use them to eat their food.

Do Cichlids Bite?

Yes, cichlids do bite. Instead, they use their teeth to rip apart food and often pull it into their mouths with suction. Some of the larger cichlids can be pretty aggressive when feeding, so it’s essential to keep a watchful eye on your tank if you have one of these fish in it. In addition, research has shown that some cichlids have been known to bite humans. Mature males of the genus Crenicara can become quite aggressive. These are often territorial animals and will try to keep other fish from entering their territory by physically defending it with a physical altercation.

Do Cichlid Bites Hurt?

There is no consensus on whether cichlid bites hurt. Some people say that they rarely do, while others claim that they can be pretty painful. But, again, the best way to find out for sure is to ask a vet or other experienced fish keeper. In any event, it’s essential to be aware of the possibility and take appropriate precautions in case you are bitten by one of your cichlids.

Are Cichlids Aggressive?

One of the many things that make cichlids so popular is their aggressiveness. Cichlids are territorial and will defend their territory against other fish. They can also be quite aggressive when competing for food or mates. Aggression may result from the cichlid’s natural selection to survive in an environment with a high level of competition. Aggression is not universal by any stretch of the imagination. Many cichlids are considered relatively peaceful and gentle, even when given a chance for introduction to new companions. However, it’s vital that we look at the situation in totality before assuming anything about these fish – just because it says “peaceful” on a label does not mean you are likely to get one of these fish if you’re looking to buy single cichlids.

Why Do Cichlids Bite?

There is no one answer to this question, as biting behavior can vary depending on the individual fish. Some cichlids may bite because they are territorial or trying to ward off a threat, while others may do it out of instinctual aggression. 

Additionally, some may bite when they become stressed. In most cases, grinding is a behavioral response that can be considered an anti-predator behavior useful in keeping cichlid populations under control and the size of the tank down to safe levels for other fish species, with proper maintenance precautions being implemented by aquarists who are trying to protect their established colonies. Although many people claim that these aggressions exist due to socialization from human companionship during early development, this has not been scientifically proven.

Here are the top reasons why cichlids can take advantage of their teeth and bite:


Cichlids sometimes will bite because they need to defend their territory or are possessive of mates. This can also be seen as territorial aggression – where the cichlid feels that another fish is going to invade its space and tries to ward off intruders with teeth!! It is often most effective, though not always necessary, for owner-reared individuals that have been introduced into an established tank system.

Protect Eggs and Mates

Biting is a behavior used by some cichlids to protect themselves and their offspring. Male cichlids may bite other males to mark them as rivals and protect their territory from them. Female cichlids may bite other females during mate competition to control the composition of their spawn or when defending eggs or young fish.

Reaction to Fear

Yes, cichlids can bite in response to fear. Some fish species exhibit this behavior when they are startled or scared. Often, the biting is not aggressive and is simply a means of self-defense. But suppose your cichlid begins to attack other fish regularly or exhibits aggressive behaviors with you or other owners of the same hobbyist care for these animals. In that case, it might be time to seek out help from an expert.


Some cichlid species will bite during the breeding season to protect their territory and nests. This behavior is usually seen in larger fish fighting for dominance or competing with other males for mates.

How to Avoid Getting Bitten by Cichlids?

Here are some tips to avoid getting bitten by cichlids:

  • Never put your hand in the water when you have a cichlid tank in your home. If you accidentally touch one of the fish, they may think you are a food source and will bite you.
  • Suppose a fight between two cichlids comes up; back away slowly until the battle is over. Do not interrupt the fight or try to take sides. If you do, it may injure one of the fish.
  • Monitor your cichlid tank regularly and remove any uneaten food or trash if it starts to build up. This will help prevent your cichlid from attacking other fish in their tank and potentially biting you.
  • When watching your cichlid tank, be sure not to insert your hand into the water. Fish may think you are a food source and will bite you.
  • If you see one of your cichlids acting aggressively, do not try to pet or scare it away. This may make the fish more aggressive and prone to biting.
  • If you have a large tank, consider using a temporary divider to help keep the fish separated. This will prevent them from attacking each other and biting you.
