What is a Green Terror Cichlid?
The Green Terror is also known as the Andinoacara rivulatus or Gold Saum. It’s part of the Andinoacara genus, along with two other species. The most common type is the A. rivulatus from Ecuador. The Peruvian Green Terror or Silver Saum (A. stalsbergi) and A. blombergi are less well-known in aquariums.
Green Terror’s Origins
The history of the Green Terror cichlid’s classification has been complex. The first record of A. rivulatus was in 1860. Since then, it has had many names and classifications. The A. stalsbergi from Peru was recognized as a new species in 1988, first called “Aequidens” sp. “silversaumbuntbarsch.”
Introducing the Andinoacara Genus
The Green Terror is part of the Andinoacara genus, a group of South American cichlids. These species are known for their green and black scales. The A. rivulatus, or Green Terror, has scales with dark centers and light edges. The A. stalsbergi, or Peruvian Green Terror, has scales with light centers and dark edges. A. blombergi, from Ecuador, has its own unique colors.
Over time, the classification and identification of Green Terror cichlids have changed. This has caused confusion among experts and hobbyists. But, understanding the different species in the Andinoacara genus has cleared up the confusion. This has helped us appreciate these beautiful South American cichlids better.
Vibrant Colors of the Green Terror
The Green Terror cichlid is known for its bright and eye-catching colors. These fish show off deep green, sapphire blue, and bright orange or yellow on their fins and body. Some have a more muted, olive-green look, while others shine like jewels, catching the eye of fish lovers.
Their colors help them blend in and communicate in their South American river homes. The mix of green, blue, and orange helps them hide and talk to each other. This makes the green terror coloration a big reason why these cichlid colors are loved by vibrant freshwater fish fans.

|---|---|
| pH | 6.5 – 7.5 |
| Temperature | 73 – 81°F (23 – 27°C) |

To make the Green Terror’s colors pop, aquarium owners need to get the water right. They need slightly acidic to neutral water, warm temperatures, and moderate hardness. With the right care, these cichlid colors will really stand out, making the Green Terror a beautiful addition to any tank.
“The Green Terror’s colors are a true marvel, constantly shifting and shimmering as the fish moves through the water. It’s like having a living piece of art in your aquarium.”

Size Matters: How Big Do Green Terrors Grow?
The Green Terror is known for its big size. Males can reach up to 12 inches (30 cm) long, making them a highlight in any aquarium. Females, on the other hand, grow to about 4-5 inches (12-15 cm), showing a big size difference with males.

For these big cichlids, having the right tank size and water conditions is key. With proper care, they can do well and make aquarium keeping rewarding for their owners.
Green Terror: The Aggressive Freshwater Fish
Green terror cichlids are known for being aggressive and territorial. They don’t mix well in community aquariums. They should be kept with other big, aggressive fish like Oscars, Red Parrots, and Giant Gouramis. When choosing green terror tankmates, it’s important to pick fish that can stand up to them.
Compatible Tankmates for Green Terrors
Choosing the right tankmates for green terrors is key. These fish aren’t easy-going. They do best with other freshwater aquarium fish that can defend themselves and won’t be seen as prey.
- Oscars: These big, feisty cichlids are perfect for living with green terrors.
- Red Parrots: Another big cichlid that can handle the green terror’s aggression.
- Giant Gouramis: These big, strong fish are a good match for green terrors in size and attitude.
- Plecos: Bigger plecostomus species, like the common pleco, can live with green terrors without being bullied.
- Other Cichlids: Aggressive, medium to large-sized cichlid species like Severums and Jewelfish can also be good friends for green terrors.
Remember, even though these fish can live together, the green terror’s aggressive nature means you need to watch them closely. A well-designed aquarium setup is also key to keeping the peace.
Distinguishing Male from Female Green Terrors
Learning to tell a Green Terror cichlid’s gender can be exciting for fish lovers. These fish show clear differences in looks, making it easy to spot males from females.
The Nuchal Hump or “Kok”
As they grow, male Green Terrors get a big bump on their head called the nuchal hump, or “kok.” This bump is a sure sign of their gender, as females don’t have it. The kok gets even bigger as the male gets bigger, making it a striking feature.
Size Difference Between Sexes
Size is another way to tell males and females apart. Males can grow up to 12 inches (30 cm) long. Females usually don’t get bigger than 5 inches (15 cm).
Color Variations by Gender
Both males and females have bright colors, but they’re not the same. Males show off intense colors with bold patterns and deep greens, blues, and yellows. Females often have less bright colors, looking more subdued.
By looking for these differences, you can easily tell if your Green Terror is a boy or a girl. This helps you understand these interesting fish better.

Housing Requirements for Green Terrors
Keeping a green terror cichlid in an aquarium needs careful planning. These fish are lively and like their space. They need a big and well-thought-out home.
For one green terror, a 75-gallon tank is the minimum. But, bigger tanks are better since these fish can grow up to 12 inches long. They need lots of room to swim. If you plan to keep more green terrors or other fish together, add 100 gallons of tank space for each extra fish. This helps prevent fighting and keeps the peace.
The tank should be filled with different hiding places like rocks, driftwood, and thick plants. These spots help reduce fighting by breaking up the fish’s view. Also, a strong filter is key because green terrors make a lot of waste.
| Aquarium Size | Recommended for Green Terrors |
|---|---|
| Minimum Tank Size | 75 gallons for a single fish |
| Recommended Tank Size | 100 gallons or larger for a single fish; additional 100 gallons per tank mate |
| Ideal Water Parameters | Temperature: 68-80°F (20-27°C) pH: 6.5-8.0 Hardness: 5-20 dGH |
