Can Acros bounce back from RTN/STN?

[pjdiddy]

This guy had RTN and eventually it stopped and now looking better with great PE. Are the damaged part will get its polyps back?

Damaged parts will remain dead IME, but it can certainly regrow over those spots if conditions stay on track.

Yes, but it can take a long time. I usually just wait for them to put on some size and demonstrate that they are totally healthy and then I snip those parts off and make a new frag out of the live area. I have found that healthy, growing acropora will heal and regrow a lot faster than they will grow over dead skeleton.

For that particular frag, once it gets to softball size, it might have covered up that area completely... maybe sooner.

The dead parts just become liverock that a healthy acro will encrust over. Assuming there isn't a bunch of algae remaining on the dead areas.

Just recently added a Hawkins Echinata to my tank that RTN'd the first night. I thought it was dead and now a couple of weeks later it is starting to show good signs of life. I'm amazed how quickly the live tissue is starting to grow back over the smooth skeleton.

RTN in my experience is pretty much 100% mortality. STN I saved quite a few from dying.

if you fix whats bothering it in the water it should bounce back.... I would suggest not dipping it bc generally that makes it worse
