How are antennae chelipeds other walking legs and swimmerets related?
The chelipeds aren't really related to the movement of the crayfish itself, unconciously these appendages might move the crayfish, but really the chelipeds are a form of defense and used for food handling, much like the one big claw of the "Fiddler" Crab.

What is a predatory crustacean?
Crustaceans are animals with hard exoskeletons, like lobsters and crabs. A predatory crustacean is a crustacean that hunts prey and is not an herbivore.
What are disadvantages of radial symmetry?
The main disadvantage to radial symmetry (eyes on the side of the head as opposed to the front) is that vision is mostly two dimensional. A creature with eyes on the sides of its head can only focus both its eyes on an object if the object is directly in front of it. This makes the range (distance) and comparative size of other creatures and objects harder to judge. It also makes discerning camoflaged creatures from their surroundings much more difficult. For raptors (birds of prey), radial symmetry presents a lot of problems when hunting. These are overcome by various other natural systems such as improved spatial awareness and superlative hearing.
Can crayfish and turtuls go in the same tank?
You don't mention the species of either, so it is impossible to tell if one species will try to eat the other or not.
Why does a crayfish hide after it molts its exoskeleton?
