Physical Characteristics and Growth of Oscar Fish
Oscar fish, also known as velvet cichlids or marble cichlids, are large fish belonging to the Cichlidae family, native to the Amazon River basin in South America. Their typical physical traits and growth data are as follows:
Maximum Body Length
In the wild, oscar fish can reach a length of 30–35 centimeters.
In captive environments, with sufficient space and nutrition, some individuals can approach or reach the size of their wild counterparts.
Growth Rate
Juvenile oscars grow rapidly, reaching 15–20 centimeters within their first year.
Growth slows down in adulthood, taking 3–5 years to reach their maximum size.
Special Notes
Oscar fish are aggressive and should be kept alone or provided with ample space to move around.
Their body colors vary by breed, including red, white, and black variations, but there is little difference in body shape across types.
