Ive had some experience first hand with this. From reading it’s like the internal organs of a euphyllia coral. Typically happens under stress I believe. I had this on a hammer coral that was quite rampant but with the stability of my tank increasing it healed and went back to normal :) I would check parameters or try and problem solve to find the underlying issue. Should recovery over time the coral looks really healthy.Hi wondering if anyone knows of this is normal. I recently took a look at my tank and show these white strings under my coral flesh is the normal?
Yea it actually happened today. It was more opened and didn’t have the strings then a few hours later that’s when I noticed. When I get off work I’ll definitely test things. That’s for the advice
