So you’re a beginner fish enthusiast looking to add some vibrant color and excitement to your aquarium? Look no further than the baby Green Terror Cichlids! These unique and stunning fish make for a perfect addition to any tank, but taking care of their specific needs can be a bit challenging for beginners. Don’t worry, though, as this guide will provide you with all the essential information you need to ensure your baby Green Terror Cichlids thrive and mesmerize you with their beauty.

Choosing the Aquarium

Tank Size

When choosing an aquarium for your baby Green Terror Cichlids, it is important to consider their growth potential. These cichlids can reach a size of up to 12 inches, so a spacious tank is necessary to accommodate their needs. It is recommended to start with a tank size of at least 30 gallons, but as they grow, you may need to upgrade to a larger tank to ensure their comfort and well-being.
