🔬 Why So Many Species?

Cichlids are masters of evolution:

• 🎭 Adaptive Radiation → In isolated lakes, they evolve quickly into hundreds of unique species.
• 🍽️ Specialized Feeding → Some eat algae, some snails, some fish, some insect larvae.
• 💕 Unique Breeding Behaviors → Mouthbrooding, egg-guarding, and complex parenting drive diversification.
