Bleaching- Tissue lightens in color to the point of becoming white, growth slows, polyp extension can be greatly affected
RTN (rapid tissue necrosis)- Usually due to poor water quality, or a swift shift in parameters. The tissue peels off within a matter of hours.
STN (slow tissue necrosis)- Can have many sources, stressful conditions, bacterial/protozoan infection. It can be a PITA randomly striking a colonyt here, colony there until you wind up fragging stuff to keep it alive. Tissue slowly peels off in sections IME it happens in a spot stops for a while then grows again without warning.
If it's the abro I can give you another piece if that one doesn't make it, that frag was pretty low in my tank and wasn't getting a whole lot of light so make sure you move it up slowly.
I got a few starter hardy frags from Tuberider at the dec meeting. One is a pretty stag with blue tips, its not happy. The tip seemed to of lost its color but wasnt too worried as thought maybe stress as it was really cold when it was brought home. Today it seems to have lost a little bit of Tissue at the base and underneath its hot pink. Good news is the tip has colored up again. So now here is my question what is the difference between bleaching, rtn, tissue sluffing off, there is alot of sps terminolgy read and sometimes I understand but sometimes im not really confident in what im trying to describe as my problem with my coral.
