Troubleshooting Coral Decline

[ReefHog10]

Curious what your typical troubleshooting protocol is when you have a singular coral not doing well? In this case it’s a Marvin the Martian Acro. Other acropora around it are receiving similar lighting and flow and are doing great. This particular one has slowly retracted its polyps over several weeks and now really has little to no extension at all. No obvious pests or fish picking at it that I’ve witnessed. While I know it’s possible that some corals will not do well with no obvious solutions, wondering what those of you who have been able to nurse one back to health have done with good success. Thanks in advance!

I would say water parameters, flow, and light. If it's not one of those three, it can be hard to figure out, at least for me. Sometimes, for whatever reason, a particular coral just doesn't do well, even though others are flourishing

Try it in a different location… I personally don’t stress it.. I mean I got over 100 acros and everything seems happy except my green slimer at the moment it started peeing .. I’d frag it but I have 3 colonies and can’t give it away lol.. I have a big chunk I broke off laying on the bottom and it’s doing very well.:
