Hi. I recently inherited a bunch of coral from a fiend and one of them was a leather. Not exactly sure what kind of leather it is. It was perfectly healthy when i got it but my calcium and alkalinity where really high. The coral started developing this yellow discoloration at its tips and in a couple "arm pits" when the branches split off. I fixed my water quality issue over a month ago and all water parameters are in check. I performed surgery and removed the affected areas with a razor. The problem went away for a few weeks but has returned a month later. Its like a yellow discoloration of the "branches" of the coral and it appears to be rotting it away. Today i noticeed that it had "rotted" away so much of a branch that it has almost falllen off. There doesnt appear to be any small parasites eating at it and there are no obvious signs. The leather is exposed to substantial current so it isnt that... Does anybody have any idea what might be causing this? For the most part it only affects the tips and "arm pits" of the leather. Please excuse the crappy picture, taken from my cell phone shortly after the halide shut off (which is why the polyps arent out). When the lights are on the leather fully expands and all polyps come out (except for affected ones). I plan on doing an iodine dip soon but does anyone have any ideas? Anyone see this before?
