What are the best fish for cycling?

What fish are the best for cycling? For fish-in cycling? I want to cycle my fish tank by adding fish to make it cycle quicker, which types of fish will make the tank cycle quicker?

    Cycling a tank with fish means that you need to moniter the water daily, change the water as needed, which could be daily, which is going to slow down the completion of the cycle, not speed it up.  

    Cycling without fish - stuff 1-5 grocery store shrimp in a nylon stocking hanging into the water, leave the filter and heater on, come back in 2 weeks to start testing the water, when you see nitrates, but have zero ammonia and zero nitrite, do a partial water change, and do more water changes if needed to get nitrates at or under 20 ppm.
