Based on anecdotal reports that my tank should be a little more seasoned.
It’s in my frag tank about a month old.Those anecdotal reports always make me wonder for their basis, and I feel its more down to husbandry than tank conditions.
Example - when I set up the 105g, I did not wait the required year for water conditions to stabilize or for the tank to 'age' before adding nems. I added 3 within 2 months, but I keep my water clean, maintain water changes, and occasionally dose minerals. All 3 are flourishing and happy as clams. Of course there are exceptions like waiting on pod population to stabilize for a mandarin, but I've wondered if the 'tank stabilization wait' is just, as you said, purely anecdotal and based on opinion.
Mark, what age was your tank when you added the first clam?
