Looking for advice on first coral in 6-7 month old tank.

[Xyres]

So my work recently got a bunch of Frogspawn frags from a local reefer. We also have a couple small mushrooms as well as devils hand, a very nice looking brain and a torch. As someone who is just beginning reefing what would be best for me?

My water parameters are:

PH: 8.2
Ammonia: 0
Nitrite: 0.1
Nitrate: 2-3

In my tank I have:

Hermit crabs
Pom pom crab
Orange spotted diamond goby
Red stripe angel
Two ocellaris clown fish
Two cleaner shrimp
Four snails

This is in a 55 gallon with skimmer, LED lighting and high water flow.
