Hi Riley,
I have always been told from hobbyists keeping the hallucinations that they light low light and low flow.... Looking at your pic above it appears as though the hallucinations are on the same rack as sps requiring much higher lighting and flow... Personally, I would move them lower to your sandbed...
I would find a spot for them and just leave them NBA
. I don't think you have had them much more than a couple weeks and they may have suffered in my tank from very low nutrients.... I'm hoping you can get them looking nice again....
I doubt anybody here in this country is going to be able to provide you with any kind of info on this particular zoo. Perhaps try posting on r2r forum would get you much better advice IME . Sometimes a single coral just doesn't want to do well and can die... I doubt there is anyone in the world who can suggest or know the exact reason why a frag goes poof when others are doing great....
It's just te way this hobby goes.... I would be thankful you are having as much success as you are because most ppl in this hobby do not have anywhere near the success you are having in the short time you have been in the hobby.... Many struggle for years and it is easy to lose thousand in corals and fish all within just 24
Hours even.... My two cents
