How many clownfish pairs in a 72" macro planted tank?

Hi, I have a 125 gallon tank that I just started and have a 4" sandbed and about 100lbs of liverock. I have other tanks, one 90 gallon reef and one 34 gallon seahorse macro tank. I am slowly transplanting my macros into the 125 gallon tank, and in the fall, after the plants are thriving I plan to add the fish. The plants are prolifera caulerpa, blue ocho, red grape, red halymenia, dragons breath. I dont want too many fish since I dont want to do water changes and I dont have a refugium. I also dont want the plants disturbed too much. I was thinking of two pairs of tank-bred clownfish, and some goby/pistol shrimps. I dont plan on having any corals.

One pair per tank is the general rule unless the tank is massive. While it works for some people, odds are you will be down to one pair once they become sexually mature if not before.

Just one pair in that tank. While it may work while they are still juveniles, once a pair starts breeding they will kill off any other clowns in the tank.
