You may try to ID it at this page (the best I could find so far):

But from your description, sounds to me like this:
They all are Diodogorgia nodulifera.
There is a good article about them:
R.Toonen
In my experience, they are indifferent to the light (have no MH there, though), as long as no red cyano or detritus build-up - they could be not only in cave.
I'm feeding mine with flow on, just adding the small pinch of food into the water.
You will see, if the food density is good. The coral's look changes from this:

to this:

May be it could be fed less, I'm trying to be on the safe side, until I find details of somebody else's experience.
If the gorgonian is close to the glass and you have a camera with macro-mode, even the simplest, you can see, how the food is processed:
This was dried Cyclop-eeze, the staple food for my diodogorgia.
This is ZoPlan and the 2nd wash of the frozen fish food:
This way you can choose, what is accepted better by the coral.
Flow: reflected from the glass high flow, but not high enough to bend the body of polyps, the feeding in this case may suffer. I had 160 gph pump in 6g tank.
If it will accumulate debris or red cyano on the branches, and basting doesn't help, the gentle rubbing by fingers is possible - I did that several times without after effects.
You can frag it easily - it recover good.
About chili:
I would advise to stick with gorgonians - they have similar polyps with chili:
but less unexpected surprises in care.
I mean medium and large polyped gorgonians, like Diodogorgia above, they could be wide shaped and vertical, with usual short tentacles and with long and curved:
