Fringe Reef eel island

I've done some searches and haven't found anything so Ill ask here.

I'm putting together a 125 2 island tank, but one of the requirements is that I get a golden dwarf moray or a canary moray. I am going two Island, one large shelf, and a smaller low rubble type area for various gorgs.

The large Island I was wondering if anyone has used pvc inside their island to act as not only structure, but a den of sorts for a small moray like this. I would love to hear experiences and see picture of any old salty pros here have done/seen this.

Thanks again in advance, hoping not to reinvent the square wheel.
