uuuummmm, I'd go with the snail idea. Crayfish are...well, they're crayfish. They have those pincers for a reason- defense. For cleaning fish, I'd recommend corys, but they need to be in groups of 4+, and a 3 gal is far too small for that.
Just because I don't type with candy and rainbows doesn't mean I'm being mean.
My opinions are based on research and experience. Ask for help!
