What Do Crawfish Eat?

Crawfish are **omnivores** , so they eat both plant and animal matter. In the wild, they’re also opportunistic scavengers, which means they’ll eat whatever food they can find near the bottom of the water.

Quick Scoop

• Plants: algae, aquatic plants, leaves, twigs, and decaying vegetation.

• Animals: insects, insect larvae, snails, worms, small fish, tadpoles, and other small aquatic creatures.
[7][3][5]
• Dead matter: they also eat decaying plant and animal material, which makes them important cleanup scavengers.
[9][5][7]
• In captivity: common foods include sinking pellets, algae wafers, vegetables like zucchini, peas, carrots, and leafy greens.

What They Like Most

Crawfish usually do best on a varied diet, and many sources note they lean heavily on detritus and other bottom-dwelling food sources. Younger crawfish tend to eat more animal-based food, while adults often consume more plants and algae.

One Important Note

Crawfish can be cannibalistic if food is scarce, so steady access to food matters, especially in tanks or crowded habitats.

Good Feeding Examples

• Sinking shrimp pellets.
• Algae wafers.
• Frozen peas.
• Zucchini.
• Carrots.
• Spinach or other greens in moderation.

TL;DR: Crawfish eat just about everything small enough to find at the bottom of the water—plants, algae, dead matter, insects, snails, and tiny animals.
