Yes, Janitor Fish do eat guppies. Janitor Fish, also known as sailfin catfish or Plecostomus, are omnivorous fish that feed on a variety of food sources, including algae, plant matter, and small aquatic animals like snails, shrimp, and fish. Guppies, which are small, colorful freshwater fish, are one of the common prey items for Janitor Fish.
Janitor Fish are native to South America but have been introduced to many other parts of the world, including Southeast Asia, where they were initially introduced as a biological control agent for aquatic plants and algae. However, they have become invasive in many areas and have caused significant ecological damage by outcompeting native fish species for resources and disrupting the balance of aquatic ecosystems.
In aquariums, Janitor Fish are often kept as a means of controlling algae growth and maintaining water quality. However, they can also pose a threat to other fish in the tank, including guppies. Janitor Fish are known to be aggressive feeders and may attack and eat smaller fish, especially if they are already weakened or sick.
To prevent Janitor Fish from eating guppies or other small fish in an aquarium, it is important to provide adequate hiding places and vegetation for the smaller fish to take cover. It is also recommended to avoid overfeeding the Janitor Fish and to provide them with a balanced diet that includes both plant and animal-based foods.
In summary, Janitor Fish do eat guppies and other small fish, but their diet is not limited to these prey items. They are omnivorous and can feed on a variety of food sources, including algae, plant matter, and other aquatic animals. In aquariums, it is important to take precautions to prevent Janitor Fish from preying on smaller fish and disrupting the balance of the tank ecosystem.
