That sounds like it should be ok. From what i have heard the Humu can get pretty aggressive not too sure about the Angler.
Your setup is kinda like ours.
We have a 90 gallon with about 50-60bs of live rock and running a Coralife 125 skimmer also. We have a Dogface Puffer, Bursa Trigger, Lunare Wrasse, Lawnmower Blenny and a Zebra Moray Eel. They all get along well together.
The Coralife CSS is a good skimmer, it is a little touchy to get dialed in at first.
