* Zooplankton: These are microscopic animals that drift in the water. Elvers primarily feed on zooplankton, including copepods, rotifers, and small crustaceans.
* Detritus: This is decaying organic matter like leaves, wood, and algae that falls to the bottom of the water.
* Small insects: Elvers will also sometimes snack on tiny insects and their larvae.
It's important to note that elvers are carnivores, meaning they primarily eat other animals. They don't eat plants or algae.
As they grow bigger, their diet changes, and they start to eat larger prey like fish and other invertebrates.
