how many fish were in the tank originally ?
what size tank are we talking about ?
Triggers, Tangs, Angel Fish and the 2 new Puffers
all these fish are fairly large to begin with and would for sure add a major spike
triggers and puffers together is like a nightmare waiting to happen
adding new fish to a QT that already is housing fish with ick is a sure fire trip for disaster , ick takes any where from 6/10 weeks to die off and your main tank should remain fallow for that same 6/10 weeks
