What Is Infusoria? (Beginner‑Friendly Explanation)

Infusoria is a collective term for microscopic freshwater organisms such as ciliates, flagellates, rotifers, and other microfauna. These tiny organisms are essential for feeding newborn fry, shrimp larvae, and other small aquatic animals that cannot eat larger foods.

What aquarists use infusoria for:

• feeding tiny fry (bettas, gourami, tetras, rasboras, killifish)
• supporting shrimp larvae
• boosting microfauna in planted tanks
• starting natural ecosystems
• feeding copepods and other small cultures
