In plants, they can eat decomposed matter like seaweed, tree leaves, and grass. In short, Crayfish are predators who can hunt for anything to satisfy their hunger attacks.

How Often Should You Feed Your Crayfish?

Crayfish eat almost anything but small portions, so feeding crayfish once a day is enough. Make sure you feed it at the same time every day; otherwise, it may mess up its routine and eating habits.

When feeding them, make you drop little pieces of 2 cm in the tank for them to eat. No matter what you’re providing it first, measure it, and only then feed. If your crayfish is younger, then reduce the portion even more.
