Clark Posted December 18, 2013 Share Posted December 18, 2013 Sorry, no pic. I have some small monitpora plates Ty gave me that I really damaged when I lost heat in the tank on two occasions. They are only a few squares inches across each and they are 95% bleached white. Do they have any chance of regaining their color or are they goners? They get good light and my water parameters are otherwise stable and centered. Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted December 18, 2013 Share Posted December 18, 2013 If they are only bleached, they should recover just fine Clark. If you see them receding, then that is a different story. Quote Link to comment Share on other sites More sharing options...
Timfish Posted December 18, 2013 Share Posted December 18, 2013 Can you see the polyps extending, that will tell you if there is and where there is live tissue? Like Ty said they should recover but I once saw a monti frag that had bleached out then grown from a 1" frag to a colony over 2" dia without coloring up. It can also be several to many weeks before you start to see any significant recovery. Quote Link to comment Share on other sites More sharing options...
Clark Posted December 18, 2013 Author Share Posted December 18, 2013 What does "receding" mean? I mean, what do I look for? I don't think I've ever seen polyps on these but my eyesight isn't so good... Quote Link to comment Share on other sites More sharing options...
Timfish Posted December 18, 2013 Share Posted December 18, 2013 That's a good question and here's my go at defining it. "Receding" or "Tissue loss" are similar in that the coral colony for some reason is loosing tissue. "Tissue loss" is more generic and typically is used for any dieoff anywhere on a colony. "Receding" is more commonly used when the loss is around the edges of a colony. With bleached colonies initially it may be difficult to tell if there has been any receding of the tissue as the part that's still alive and the part where there has been some death both look white but over a short period algae will start growing in the exposed skeleton discoloring it. "Receding" may also occur naturally in healthy colonies as the colony grows and shades the tissue around the lower parts to the extend it dies from lack of light.

Clark Posted December 18, 2013 Author Share Posted December 18, 2013 Thanks! I'll watch for all of this over the next few weeks. Quote Link to comment Share on other sites More sharing options...
