Native to South America, it thrives in groups, prefers warm water, and eats mostly plant-based foods. You can witness 3 species, red hook metynnis, black banded metynnis and blue hook metynnis in their amazing colour patterns! These unique colours appear when they are matured and in their breeding condition! | Water World Sri Lanka | Facebook
