Sun coral shedding/dying?

DPal · 04/12/2017, 12:19 PM

Looks like my sun coral is dying. I removed it from DT and hoping to bring it back. Looking at different forums about it but nothing shows a picture of this shedding.

The sun coral was doing well for 3 months but it stopped coming out to eat the last 3 weeks with target feeding using plastic bottle (Reef Roids and mysis). This morning I saw yellow bits of skin like shedding.

Anything that I can do to help it recover?

First picture was in February 2017, second pic is today.

Hi DPal,
I would try taking your sun coral out in small container of tank water and try
with some stinky food (mysis shrimp) and see if it will open. I would try the for a few day, the same time each day.

That is a stress indication which you often see when they have been shipped. Has anything else changed in the tank?

Looks like a WC issue. Also lose the Reef Roids and feed only meaty foods.

A few years ago I had something that looks similar happen to my sun coral colonies. I had about 6-8 colonies that I had for a couple of years (some much longer) and overnight most of them developed a condition that looked similar. They began losing tissue and I lost most of them. No other corals were affected.

Nothing changed in the tank, even my the picky Flowering tree coral is happy. Well the sun coral wouldn't come out and died (smelled). It was my favorite

I wanted to start a collection of yellow, orange and black sun corals.

My sun coral had a small spot of yellow skin it shredded about a month ago but it went way. mine has went 3 or 4 days without opening up before but usually opens every night
