So, when you go to add more fish to the tank, there's still a period of time where the bacteria are playing catch-up with the newly increased bioload, which could cause ammonia/nitrite spikes that could be dangerous.
2) If you don't want to keep those fish in the long term, you need to catch them and move them to another tank or return them. Sometimes this is a huge pain.
3) If you're cycling with fish, you have to do water changes during the cycle in order to keep those fish alive. This is time consuming and costs money.
4) Most importantly, subjecting fish to the rigors of living in a tank full of toxic water is something every fishkeeper should be discouraged from doing. Even if your fish survive the cycling process, there are health risks associated with long-term ammonia exposure. Long story short: fish-in cycles are unnecessarily cruel.
This is exactly what is happening to me with my daughter's tank. Fortunately, in the past I don't recall any horrible deaths from cycling except in a saltwater tank. Even though I tested and tested then, I may not have been as worried because of my successful memories of when I was a kid and had fish. They did not even teach us to cycle and the fish always seemed to make it. I remember back then when I was a kid,e we tore the whole tank down to clean it from time to time, which is a known no no now and when I had fish not long ago as an adult. I think the older we get the more precautious we become.
I am all for the fishless cycling. I can't even handle worrying about feeder goldfish and can't even feed anything goldfish. LOL I have a real soft heart for animals.
