Green Terror

Andinoacara rivulatus, commonly known as the Green Terror, is a species of cichlid fish native to South America. Here are some key features and information about this species:

1. Origin: Green Terrors are primarily found in the rivers and lakes of South America, particularly in the Pacific drainage of Ecuador and northern Peru.

2. Appearance: They are known for their vibrant and striking colors. Adult Green Terrors typically have a greenish-blue body with orange or red markings on their fins. The males tend to be larger and more brightly colored than females.

3. Size: These cichlids can grow relatively large, with males reaching up to 12 inches (30 cm) or more in length, while females are generally smaller.

4. Habitat: In their natural habitat, Green Terrors inhabit slow-moving rivers and areas with submerged vegetation. They prefer environments with hiding spots such as rocks, caves, and driftwood.

5. Behavior: Green Terrors are known for their territorial and aggressive nature, especially during the breeding season. When kept in captivity, they may display aggressive behavior towards other fish, especially if they intrude into their claimed territory.

6. Diet: In the wild, their diet consists of a variety of foods including small fish, insects, crustaceans, and plant matter. In captivity, they can be fed a balanced diet of high-quality pellets, live or frozen food, and occasional vegetables.

7. Aquarium Care: If you plan to keep Green Terrors in an aquarium, it's important to provide ample hiding places and territories. The aquarium should be sufficiently large to accommodate their size, and water conditions should be maintained within their preferred parameters, including slightly acidic to neutral pH and warmer temperatures.

8. Breeding: Green Terrors are known to form pairs for breeding. The female typically lays eggs on a flat surface, and both parents are involved in guarding and caring for the eggs and fry.

9. Compatibility: While Green Terrors can be kept with other large and robust fish, they may show aggression towards smaller or more passive tank mates. It's important to carefully choose tank mates and monitor their behavior.

Remember that keeping cichlids, especially those known for their territorial behavior, requires careful consideration of tank setup, tank mates, and water parameters to ensure the well-being of the fish. Always research and understand the specific needs of any fish species before adding them to your aquarium.
