Spider.
the grasshopper is more closely related to the housefly.
spider but octopuses can have more or less arms due to predetors or groth malfunction
The octopus is a hunting carnivore, much like a tiger in the jungle. Depending on the size and species of the octopus they will eat fish, sharks, clams, and much more.

Lousiana supplies more than 90% of the crayfish production
I think from disecting a crayfish in my Biology class, that crayfish have 5 sets of different appendages. All in all, the crayfish we disected had 36 actual appendages. Appendages are areas on an animal that "stick out". Kind of like our arms and legs except crustaceans and other animals have more, and can grow them back if they are cut off. Like I said, total, our crayfish had 36 appendages from anterior to posterior. There are a total of 38 appendages, 19 on each side.
The crayfish is more vulnerable to attack from it's belly or ventral side. The dorsal side has armor like plates., while the belly is mostly legs and unprotected internal organs.
Without much more information the question can not be answered accurately. Crayfish are scavengers and guppies are not their natural prey. If the crayfish is small enough and your guppies don't have long flowing fins then the guppies may well be too fast for the crayfish to catch. So the answer then would be none. Are you feeding the crays dead guppies? If so I would add one and see how long it takes the crayfish to eat it. Then I would add more and more dead guppies one at a time as the crayfish devours them. As the crayfish grows so it will eat more.
yeah
Crayfish have a limited ability to regenerate lost body parts, including limbs, but they generally do not regenerate eyes. If a crayfish loses an eye, it may not grow back; however, it can sometimes compensate for the loss by relying more on its other senses. Regeneration is more prominent in limbs than in complex structures like eyes.
The immediate impression from the question is that the crayfish is much more likely to be traumatized.
