The Oscar may attack your beloved appendices, but you should expect any serious damages. Oscars don’t appreciate any foreign creatures in their habitat, including those looking like human fingers. Some may even act more aggressive instinctively since Oscars are extremely territorial and will even attack human hands if any happens to swim in its habitat. So, the Oscar won’t bite you, but it will poke you with its lips if you insist on triggering them. It’s only then when the pharyngeal teeth will take over, breaking down the victim and preparing it for digestion. Instead, like I’ve already mentioned, they will create a suction effect with their lips and mouths, sucking the prey into their mouths. They can’t bite chunks out of their prey since they don’t have any mandible teeth. They’re not biologically built for that, which is why Oscars only consume food large enough to fit their mouths. It’s more like a poke, sometimes combined with a suction effect, since Oscars can’t really bite. All cichlids will display food-related aggression since it’s written in their biological profile. I suggest adopting a similar approach for community tanks where you have several species of cichlids present. This will minimize Oscar’s aggressive tendencies since there will be plenty of food for everyone. This means sprinkling food in different areas of the tank to force the fish to spread out. If you do have more than one Oscar in the tank, I advise feeding the fish separately as much as possible. It’s one of the reasons why Oscars are often kept alone. They won’t share their space, food, or females with any other Oscar and will consider most fish in their environment to be competition or even enemies. Oscars are cichlids, so it’s only natural for them to display predatorial behavior and showcase aggressive tendencies during feeding. So, they won’t inflict any meaningful cuts or punctures. Only if you insert the finger into its mouth, you should expect some moderate pain, but the Oscar’s teeth aren’t that sharp anyway. At most, your Oscar will nip at your hand with its big and powerful lips but won’t be able to cause any relevant damages. This anatomical feature prevents the Oscar from inflicting any serious harm to potential attackers. The pharyngeal teeth have a similar role, breaking down the food even further before going down. There, internal muscles direct the prey to the back teeth, which kill and grind it. They are suction fish, which means they get close to their prey and use a powerful suction effect to drag the victim into their mouths. Unlike predatory fish like piranha or sharks, Oscars don’t have any teeth on their mandibles because they don’t need any. Yes, they do, but they’re all located at the back of the mouth and in the throat. It’s a tactic designed to scare more than hurt you since Oscars don’t have any visible teeth to bite with.īut more on this issue in the upcoming section. That being said, they might poke at your hand if you place it in the water. They will greet you by coming near the tank’s walls or swimming to the water’s surface if they think it’s feeding time. Generally speaking, Oscars recognize their owners and will show that each time you come close to their tank.
Some may be more aggressive and territorial than others and will react instinctively to anything invading their space, including your hand. It also depends on each fish’s personality and circumstances. To put it bluntly, no, Oscars don’t bite, they poke. Given their naturally larger size, predatorial behavior, and mean look, it’s only natural for the question to arise – Do they bite?
Oscars are large cichlids that display territorial behavior and don’t play well with other fish species.
