Here’s what you should know about a 5-inch Green Terror: Size and Growth: While a 5-inch Green Terror is still relatively small compared to its potential adult size, it’s already a good size for its age. Male Green Terrors can grow up to 12 inches (30.5 cm) in length, while females tend to stay smaller, around 8 inches (20 cm). Growth can be rapid, with some fish reaching 6 inches in about 5 months. Aggression: Even at this size, Green Terrors are known for their territorial and aggressive nature. You need to be mindful of their temperament when choosing tank mates. While they may be relatively peaceful as juveniles, they become more assertive as they mature. Tank Size: A 5-inch Green Terror will still need a sizeable tank, but it will need to be upgraded as the fish grows. A minimum of 75 gallons is recommended for a single Green Terror, and a compatible pair will need even more space, upwards of 150 gallons. Diet: A varied diet is crucial for a growing Green Terror. Offer a mix of high-quality cichlid pellets or flakes, along with live or frozen foods like brine shrimp or bloodworms. You can also include some plant-based foods, such as spirulina flakes or blanched vegetables. Tank Mates: Choose tank mates carefully. Only add fish that can stand their ground and are similar in size to the Green Terror. Other cichlids of similar size can be compatible, but avoid overcrowding the tank. Introducing the Green Terror after other fish are established can help reduce aggression. Important Notes: Water Quality: Regardless of the fish’s size, maintaining excellent water quality is crucial. Perform regular water changes to keep nitrate levels low and stable. Breeding: If you have a breeding pair, be aware that their aggression levels will be at an all-time high during spawning. If you’re keeping a 5-inch Green Terror, you are likely witnessing its transformation into a larger, more colorful, and potentially more assertive fish. Providing a spacious and well-maintained aquarium, along with appropriate tank mates and a balanced diet, will ensure your Green Terror thrives.
