Welcome to The Reef Tank!
Your set-up sounds good and agreed with the advice on the soft corals. Capnella and "
Colt corals" would do well, too; they are soft branching corals which I like better than most of the Xenia. The Capnella is great because it frags itself, LOL, by dropping little branchlets that attach to just about anything easily and are ready for trading in a very short time. Some of the hardier leathers (not the yellows) would do well in there also.
I'd add a little more live rock, but not much. Small tanks get crowded fast and it's easy to do an extra gallon or two water change on them to keep water parameters in top notch condition.
Have fun!
