you are probably OK on BIO load for now since you only have a couple of larger fish and the rest do not produce a huge amount of waste. A 132g may sound huge, but unless you have a large sump to go with it you are still somewhat limited. In comparison I have a 90g with a 30g sump( only 12g less than you) and 8 fish which I consider myself maxed. Remeber your fish will grow. Those 1" chromis can someday be 3-4" monsters.
Also, keep in mind that all that rock displaces water volume. In reality my 120g of capacity is probably more like 100-110g because of all the rock I have.
My larger concern is how fast you are adding all these fish. It seems like every few days you are posting about a new addition(not using QT if I recall). By adding the fish so quick you are not allowing your sytem to naturally react to the increased bio load. If you continue adding fish you could cause you tank to go back into a mini cycle and risk losing all you have with an amonia spike.
, the best advice anyone can give in this hobby is to be patient and take it slow. While you are waiting do as much research as you can on any potential additions or changes you want to make.
This is defianetly not a hobby for the impulsive. Just think about how much time and $ you have invested so far and you are just starting out. I think a lot of SW
hobbyist burn out and leave the hobby because they try to ovedue it right away and when their system crashes they give up. I have almost been there myself. My current system is 3 + years old and still growing.
Bottom line, Do not do anything else for a few months and let your system mature. A SW
setup really does change a lot in the first 6 months. You do not want to reach your max bioload right away. If a natural swing occurs it leaves no room for error if your bioload is already maxed out.
