Here are the points outlining why keeping guppy fish with Oscar fish is generally not recommended:


✔ Size Discrepancy: Oscars are considerably larger than guppies. Oscars can grow to a substantial size, while guppies are small in comparison, making them vulnerable to being seen as prey by the Oscars.


✔ Aggressive Behavior: Oscars are known for their territorial and aggressive nature. They may harass or view smaller fish like guppies as potential prey due to their hunting instincts.


✔ Risk of Predation: Oscars have large mouths and can easily swallow smaller fish like guppies, posing a risk of predation or injury to the smaller fish.


✔ Differences in Water Parameters: Oscars and guppies have different water parameter requirements. Oscars need larger tanks and specific water conditions compared to guppies, making it challenging to maintain suitable conditions for both species in the same tank.


✔ Potential Stress: Housing guppies with Oscars can result in stress for the guppies due to the aggressive behavior and predatory instincts of the Oscars.


✔ Separate Needs: To ensure the well-being of both species, it's advisable to house them separately in tanks that cater to their individual needs, preventing potential conflicts and providing a suitable environment for their growth and health.
