shaywood Posted September 20, 2008 Share Posted September 20, 2008 Last night this coral frag was looking great. This morning most of it's color is gone, except for the top 1/3. Next to the coral is a astrea snail and at the base of the frag is a lot of droppings (like something spent the night at the frag). Is it possible that the snail eat the color off of the frag? I have had this happen to two frags now. All water parameters are great, so I don't think its a bleaching problem. Shawn Quote Link to comment Share on other sites More sharing options...
spectra Posted September 20, 2008 Share Posted September 20, 2008 Looks like RTN to me. Once this happens pretty much forget about it. If it was a bigger colony sometimes it can be saved by fragging a good pc off. I have had this happen and it sucks. Quote Link to comment Share on other sites More sharing options...
Guest Snorkelwasp Posted September 20, 2008 Share Posted September 20, 2008 i dont think it would be a snail...usually snails and hermits are confused with the culprit but they are just doin their jobs of janitor and cleanin up the mess Quote Link to comment Share on other sites More sharing options...
stylaster Posted September 20, 2008 Share Posted September 20, 2008 i agree with spectre ,rtn, best you can do is frag off a good piece without any die off and glue it to a frag plug and hope it recovers, the snail being there is just incidental Quote Link to comment Share on other sites More sharing options...
markdadof2 Posted September 21, 2008 Share Posted September 21, 2008 What is RTN? sorry for my ingorance Quote Link to comment Share on other sites More sharing options...
R-3 Posted September 21, 2008 Share Posted September 21, 2008 Yep definately RTN! RTN is Rapid Tissue Necrosis. It is a disease where the tissue starts to "slough" off rapidly. Instead of a acro slowly starting to die RTN usually happens overnight almost. Later Ryan Quote Link to comment Share on other sites More sharing options...

dsoz Posted September 21, 2008 Share Posted September 21, 2008 Take a sample of your water to WAVES, and have Joel do a phosphate test (it costs $1). He uses a special machine to detect trace amounts of phosphates. Maybe some of the other LFSs have a colorimeter to test for phosphates, check around. I know that Joel has one, and he is the one I go to if I want my phosphates tested I thought that my water quality was OK, but I had two torts do RTN, and sure enough, I had some phosphates in my system. dsoz Quote Link to comment Share on other sites More sharing options...
shaywood Posted September 21, 2008 Author Share Posted September 21, 2008 Phosphate is zero. Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted September 21, 2008 Share Posted September 21, 2008 I agree with the RTN therory. Maybe the snail was eating the slough off the coral and that is why it was around. Thats just a guess. Quote Link to comment Share on other sites More sharing options...
