About two weeks ago I purchased a neon pink tip torch it’s my most expensive coral. For the first week it was doing so well opened up massive and was doing perfect. A week later I went to glue a new coral frag I bought and I grazed the torch with my hand it closed up and was bothered for a day or so. Then it was my time for a water change and after my water change my torch hasn’t opened back up. It’s been closed since. I thought it might of gotten an infection so I did a coral dip on the torch and placed him back. Light and flow hasn’t changed at all. My water parameters are all in check. Any help. It’s the third week and I see my torch more opened and not closed but its tips are all curled up. My tank is 5g nano btw. I will attach pictures of the torch in the three weeks in order of how it’s looking. Keep in mines every other coral in my tank is doing more than well and I have other LPS
