Bad looking acro

[Toadfish]

Is this RTN? If so what should I do? This has been slowly progressing over the last few weeks, going in and out. Finally decided to post a pic. Thanks in advance. BTW this is the back of the coral but I'm beginning to notice it slightly in the front.

one more from the side

Hey Toadfish, RTN is very fast, no two week thing. With RTN the skin of the coral actually peels off the skeleton (can't spell today)

It appears to me that the coral is not in a place where it is getting enough water movement. it looks like the rocks around it are blocking the water. I would move it somewhere where there is GOOD flow to get between the branches.

Look close at the coral and make sure you don't have a crab in there that is eating the polyps of the coral. Don't misunderstand that part, there are good crabs that live in the corals with no problems, but there are others that hide and eat the polyps.

Have I confused you yet? LOL

No I understand, there is a crab but I have never seen him eating the Acro. I'll keep any eye on him, and move the coral in the meantime. thanks

was going to say the same thing light and water movement needs improving. just a guess though .i have lost a chesterfieldensis slowly over a few weeks that i could not explain .
