overpopulated?

I was thinking about adding a niger triggerfish and a dragon wrasse to my tank(details in signature) this weekend, but was wondering if it would overpopulate the tank. also my lunare wrasse seems extremely peacefull(maybe cause he's not the boss of the tank) but would he attack the dragon, he's never attacked any newcomers. One last thing is i also added the angelfish about two weeks ago, too soon to add more fish?

 

I think it would be a lot of bio-load.To many fish already. Two large angels in a 100gal is already enough. I would actually only keep one large angel in that size aquarium.
Don't get me wrong. I don't mean to discourage you but IMO the overall fish's health depends on ur ability to keep your water pristine and sufficient space to grow.
The snowflake, yellow tang and the emperor angel all require lots of swimming space and if they don't get that, problems are likely to occur in the future.

 

I have to agree here with siddique. You have several large fish already plus the eel. I wouldn't risk having issues arise with the water quality later with the livestock you already have.

 

if it's too much bioload then how come my aquarium still seems empty, btw I only have one angel, a juvenile emperor. also the snowflake is a baby(even though i know he will grow big). Thanks for comments

 

Saltwater aquariums that are properly stocked always seem empty. If you see a marine tank full of fish there is surely a huge huge sump hiding somewhere near by. I would wait a month between adding new fish to let the bacteria get used to the bio load.
