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.

How many guppies per week will a crayfish- eat I am looking forward to establishing a semi natural balanced ecosystem and am thinking of using crayfish as pop control Thanks- Any help?
it is depending on how tall the tank is and how much water is in it i have a medium sized tank full of water and i bought 15 guppies and 2 crayfish and after a month only 3 are gone and 2 died ofsickness i know this because there was no bruises. if only you plan on feeding them guppies have low water and fat and slow guppies also feed the crayfish fish food sometimes because they will starve without it because catch rate is so low also they don't only eat fish like most people believe they eat fish about 1 to 3 times a month because of catch rate they eat worms,plants and other waste.
