Crayfish with Oscar and parrot

[Rabin Singh]

From what I understand crayfish are opportunist's and pretty voracious. I'm thinking of getting one to go in the tank with Oscar and parrot. Since they both tend to swim in the top part of the aquarium, I think they would not be affected by the crayfish. So just to be very sure that I can keep the fishes safely with the crayfish I decided to post this. So what do you guys think??

Got my brother a four inch one thumb remove just for the safety of the fish I gave him. With out that claw he can't really hurt your fish as bad but there still an opportunity it still could hurt it or have it with my luck 3 inch electric blues tag team on it trying to eat it but finally stopped. How you got way bigger fish they do feed on crayfish if they wanted to
