The Jaguar cichlid (Parachromis managuensis) is a striking and aggressive freshwater fish native to Central America, particularly in Nicaragua and Honduras. It gets its name from the jaguar-like spots that cover its body.
 
Here are a few key points about it:
 
Size: Can grow quite large—up to 14–16 inches (35–40 cm) in captivity.
Temperament: Very territorial and aggressive, especially during breeding. Best kept alone or with other large, robust fish.
Tank requirements: Needs a large tank (minimum 75 gallons), strong filtration, and hiding spots.
Diet: Carnivorous—enjoys high-protein diets like pellets, shrimp, fish, and insects.
Lifespan: Around 10–15 years with proper care.
