How many fish should I add?

[TripleJ21]

Hello everyone. I'm in the middle of stocking my 75 gallon reef. In order to save money on shipping, I was wondering if I would be able to purchase and add three fish at the same time into my tank. Would it be too much on the bioload at one time?

Here are the fish:
Green Canary Blenny: 2 in.
Blue Reef Chromis: 2in.
Half Black Anglefish: 2 in.

Also, I know the angel should be the last fish to add, but do you giys think I would be able to add a tang afterwards? Maybe adding an angel that is larger than the angel would aid against aggression?

People are going to ask for more info about your tank, how long has it been up and running. What's in there there now? Ect.....

Good point. My tank has been running since June (5 months). I have 80 pounds of live rock and sand. No sump. Just 2 Bak-Pak 2's. I do a 20% water change every other week. My corals are softies and LPS.

My current inhabitants are:
2 Occ. Clowns
1 Barlett's Anthias
1 Yellow Fin Fairy Wrasse
1 Flame Hawkfish
