* Zooplankton: Tiny animals like copepods, rotifers, and larvae.
* Small fish: Fry (baby fish), and sometimes even larger fish depending on the shrimp species and size.
* Worms: Small worms like tubifex worms and bloodworms.
* Insects: Larvae and pupae of insects that fall into the water.
* Other invertebrates: Snails, clams, mussels, and other crustaceans.
It's important to note that shrimp diet varies greatly depending on the species, age, and habitat. Some species are more carnivorous, while others are primarily herbivorous. Additionally, availability of food in their environment plays a crucial role in their diet.
