I suspect salinity shock and not lighting issues for the problem with your coral.

How slowly should I raise my salinity?

Hi All. I finally posted a picture of this coral in my photo gallery. I'm not sure how to insert the picture into the thread.

That coral is definitely bleached. Glad to see that it's not RTN!!

To post pics in a thread, just copy the image tag and paste it right into your message:

Thanks amcarrig. But what is RTN? Sorry I'm new to the acroynms.

RTN=Rapid tissue necrosis. It's still unclear what exactly causes this condition but the major symptom is rapid tissue loss. There is usually no recovering when a coral has RTN. When a coral bleaches, it simply expels its symbiotic algae (zooxanthellae) giving the coral a white "bleached" appearance. Most corals can recover from this condition with proper care.

What would you suggest for proper care?

Just keep your water parameters in check and place the coral lower in the tank if it's getting too much light. It takes a while but the coral should grow its zooxanthellae back if it doesn't get stressed again.

Sounds good amcarrig. Thanks again.

Can you help me identify what the three spots are on the front it. I think they might be worms, not sure.

Your picture link is a bit squirrelly. Can you try to post it again?
