For the first part, the compelling thing about corals is the special lighting that they need and is typically available only in DT. I don't suggest eight weeks without proper lighting for corals. QT corals has such an inherent problem.
For the second part, no no no, you do not have a small cycle want you add fish. Go back to my question. How would you cycle a new tank for a ten inch queen angel? There should be and will be no ammonia for this ten inch fish whatsoever. Even ten such fish.
For bacteria population change according to bioload change, the process is rather slow, Three weeks at least.
Many LFS have wide differences in bioload for their tanks for systems. You will typically have at least a few weeks of low bioload before the bacterial population declines significantly.
Also, just think about a typical cycle. There will be typically 2-3 weeks when ammonia has been exhausted (nitrosomous max out) and nitrite peaked. The nitromoous for two-three weeks have little ammonia to feed on (while nitrobacter grow), yet they survive.
If an aquarist makes sure that the nitrification capacity is very high at the end of a cycle, there will be at least about a month (may be more) when the nitrification capacity remains very high without bioload.
