I bought this Lobo yesterday in hopes of nursing it back to health. Very ambitious since I'm new to this hobby but it spoke to me

and I couldn't refuse. (of course it was at a drastically reduced price).
Attached are pictures but here's added description. One Lobe has flesh but in quite a few areas along the edge the spikes (skeleton) is exposed. On the second lobe, to the left, only a small section of flesh exists. There is a 3rd lobe (not pictured) which there doesn't appear to be any living tissue.
This is what I've done so far and I would greatly appreciate any advise to help me, help Mr. Lobo.
- Yesterday I took around an hour to acclimate it.
- I added the Coral vitamins to the tank (already a part of my routine)
- This morning I target fed it Coral Smorgasbord and again this evening. (no reaction)
