What is this?

Can anyone tell me exactly what this is? I was told it was a blue lobster but is there a different name for it?

some people call it an electric blue crayfish, they are not real lobsters, just crayfish

Do you know how big it gets? I got it from someone and I'm trying to make sure I can take care of it properly!
