Pods? What are pods? They are tiny little bugs that fish consume as part of their normal diet. Mandarins, Wrasses and more enjoy these delicate crustaceans. In a well established refugium, you should see many pods scurrying around. This is anAmphipod, which is recognized by its shrimp-like shape. Copepods are straight in shape, and look like tiny bugs. Amphipods are much easier to see. Reef-safe.
