Characidium schindleri is a small freshwater fish up to seven centimeters long. It lives in clean fast rivers and streams in eastern Brazil and feeds on small invertebrates.
Characidium schindleri differs from related species by a precise pattern of dark stripes and spots on the body. This fish helps maintain balance in rivers by eating insect larvae and becoming food for larger fish.
Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
