How many fish to introduce at once post fishless cycle?

[TX_REEF]

Hello! my tank should be finished up with its cycle (0 nitrite and ammonia) in the coming days. The system is 90gal total volume, 72gal display. I was planning to add a pair of juvenile clowns, but would also like to add a six-line wrasse. Would it be ok to add all 3 at once, or is it too much and I should space them out? I know traditionally "1 by 1" is the safest approach, but wondering if the system size and the fact that it was fully cycled and proven to handle ammonia already might give it some more flexibility. Thanks for your input.

You should be fine, but I'd add the wrasse a little later. I added 2 clowns, a lawnmower and a clown goby to my 26g peninsula without issue.

When fish are added, the bacteria population increases with the new load converting the waste to nitrate.
Adding too many fish up front will exceed what the bacteria will handle which is why its best to stock fish slowly

Take your time. Adding a small pair of clowns is a good first step. I recommend waiting to add a six line wrasse for 2 reasons.
1- Space out the bioload increases as your tank matures. Wait 2 months to see how the 2 clowns are doing in the tank before choosing a 3rd or 4th fish.
2- A six line can often be a bully, especially to other wrasses. So wait to add him until you decide if you want to add any other docile fish or other wrasses. Add your gobies, cardinals, jawfish, firefish, blennies first.
