Sea monkeys are neither herbivores nor carnivores. They are omnivores. This means they eat both plants and animals.

Here's what they eat:

* Algae: A primary food source, they eat a variety of algae found in their habitat.

* Bacteria: Another important part of their diet.

* Small organisms: They also eat small organisms like protozoa and microscopic invertebrates.

So, while they may nibble on plant matter like algae, they also consume small creatures, making them omnivores.
