Stocking a 49 gal Column Reef Tank

Hoping I can get a little help here with regard to adding fish to my reef tank. To date my focus has been stocking corals, but I believe I've reached my max on what can fit comfortably in my 49 gal column tank and have room to grow. I'm considering whether or not I can add any more fish. Here's what I have:

Corals:
Hammer
Frogspawn
Duncan
Neon Green Tree
Yellow Polyps
Chili Coral
Montipora Digitata
Open Brain
small polyp colony
mushrooms
fuzzy mushroom

Inverts:
3 turbo snails
2 hermit crabs
1 cleaner shrimp

Fish:
2 clowns

Can I add more fish? If so any suggestions on which ones? Again this is a column tank, more depth than length for swimming. Am I maxed out already?
