This technique avoids his large, powerful front claws, which he'll use to pinch when threatened. If he latches on, immediately submerge him in his tank where he feels comfortable; he should happily let go. To avoid disease and health problems, keep your crawdad's tank clean. A simple aquarium pump will filter out impurities and aerate the water.

These decapods are fully capable of eating small, slow-moving fish. That means they can become a bit problematic if you stock your tank with daring fish that like to swim close to the crayfish. These creatures might even attempt to grab larger fish if they venture too close. Dead or diseased fish are not off the table. Another potential issue with crayfish?
Crayfish love snacking on plants. Lush aquariums filled with greenery are great for most freshwater fish and invertebrates. But with the crayfish, you have to plan for some potential destruction. More delicate vegetation will be no match for your crayfish.
They will use their larger front claws as the first two pairs of walking legs to shred fine plants to bits! Hardy and fast-growing plant species are tough enough to survive crayfish snacking. Some good examples include hornwort and Java fern , but anything else will get destroyed slowly as the crayfish feast. Crayfish come from pretty filthy environments. Typically, they inhabit streams and rivers. Instead, they stick to the muddy riverbed.
You see, their diet in the wild consists of primarily decaying matter. Fast currents that sweep dead plants and animals downstream. Using their claws, they grab onto anything that manages to flow by.

Just like lobsters, they have pincers and are colored brown, gray, and red.
They are members of the family Parastacoidea and the family Astacoidea. Crawfish breathe through feather-like gills. Some of them could be found in streams and brooks where freshwater is abundant, while others live in ditches, paddy fields, and swamps. Many crawfish cannot thrive on polluted water, although a few of them are hardier. Crawfish eat plants and animals, either decomposing or living and detritus. There are three families of crawfish, two in the Northern Hemisphere and the other in the Southern Hemisphere.
The rest can be found in Eurasia, North America, and Japan.
