I'm sure a lot of hobbyists are aware of these "hardy" fish for use in cycling a tank. That would be a useful resource if it included the most important part of cycling and that is testing the water parameters. It doesn't matter how hardy the fish are if there still remains a lack of knowledge about the nitrogen cycle.
I've had the experience of doing both methods. Due to this lack of information, the first attempt killed several hardy fish due to lack of knowledge of the nitrogen cycle. The second attempt was successful because at that point I had the knowledge and purchased the test kits to monitor the levels and adjust them before they became toxic. I then tried the "fishless" cycle and found it to be extremely frustrating (watching a couple of shrimp decaying in a 75
gal tank is to be honest, an eyesore and embarassing when company came over).

Most folks find this forum when they research sick or dying fish. It is usually within the first or second week of a new tank set up. If folks could get this information prior to setting up their tanks, a lot of unneccesary fish deaths would be the result.
