morays and puffer fish

I'm setting up a Red Sea Reefer Deluxe XXL 750 (200-gallons) and I'm planning to put a clearfin lionfish as the main fish. I was originally thinking of Niger triggerfish since they were the least aggressive of the triggerfish but after browsing through some forums, they often said that...

Has anyone run into issues with keeping dogface puffers with Hawaiian dragon morays? I have my HDME in a 125 along with a 4" Picasso and a Whitemouth moray. Both eels are around 18"
