It is an acronym for Rapid Tissue Necrosis, which means the tissue is dying fast. Ever heard of 'flesh eating disease' on shows like ER? It has to be cut off quickly before it gets into your entire body. Acropora suffer from RTN, and it just happens seemingly for no reason whatsoever.<!--break--></p> <p>Here's a lovely piece.<br /><br /><img src="http://www.melevsreef.com/pics/06/04/brent_sps_0409.jpg" /></p> <p>And then a week later I saw this:<br /><br /><img src="http://www.melevsreef.com/pics/06/04/rtn_start.jpg" /></p> <p><img src="http://www.melevsreef.com/pics/06/04/rtn1.jpg" /></p> <p><img src="http://www.melevsreef.com/pics/06/04/rtn11.jpg" /></p> <p>Basically, the tissue begins to look very thin, and just sloughs off the coral skeleton in flakes or disintegrates.
