Plate coral bleaching?

[FarmerTy]

Really, never? Not even broadcast feeding? Glad they're doing well for you. All my research told me feeding them is very important. Mine gets a little bit of everything from phyto and reefroids to pellets and my frozen blend i feed the tank. Probably picks up a little food almost every day and target fed once a week.

I do feed my fish so incidental feedings will occur but even when I had it in my sump with no fish, they did fine. I would imagine the GFO caused it to react and lose color unless there was a lighting change associated with them too.

Why not feed it something easy for it to eat?
Spot feed with BRS reef chili or other small pellet food. Would be easier for the coral to Take up the nutrition in the food.

Why wouldn't meaty foods be considered easy? Pellets are hard and reef chili is a super fine particle designed for smaller polyps. I use finer particles to start a feeding response but then feed a nice meaty chunk. It devours the fresh food in seconds versus pellets where most of the time it spits them out

I think if someone is sick or weak do I feed steak or ensure?

All my corals and nems show great feeding response, growth and health with reef chilli. Just food for thought.

Hmmm, didn't I say I actually use the finer particle foods? Not sure why your so defensive? Did I insult you any way? Can you go ahead and explain how pellets are easier to digest then a fresh piece of food? I'll use your logic, if I'm sick I'd rather have fresh food rather than dog food. Make sense jimmy? I use reef chili, reef roids, reef frenzy, they are great foods and never said they werent.

I took a PAR reading and that shows 67 PAR on the sand bed next to it. So I'm pretty sure it's not due to too much light.

That 67 par might not seem like a lot, but the number itself is less important than the degree of change. Adding a carbon reactor can drastically change light transmission rates, especially in areas like the bottom of the tank. That's generally why I prefer putting bags of carbon outside areas of direct flow, like sitting in the sump, rather than using reactors. They can strip yellowing compounds out of the water so fast the corals don't have time to react. Unless you are diligent about changing before the carbon is exhausted, you might wind up with a similar issue next time you refill it too...

Thanks for the info. I'm trying to remember what my PAR readings were the last time I took them (we are packing to move, so don't know where the paper is I wrote them on), but I know it was right around in that same range. I don't think there would be a drastic change from adding the carbon since the tank is so new.

I did feed it a chunk of fresh raw shrimp today and again it gabbled it right up. I've got about 2.5 weeks before I have to move the tank to the new house, so hopefully his guy recovers pretty soon.

Just and update to this thread. I ended up only direct feeding the plate coral 2-3 times. Each time it ate the shrimp quickly. The color did return after a couple more weeks and he was looking pretty good before we moved house.

Due to some unplanned setbacks at the new house, the tank did not get setup for about 3 weeks and everything stayed in two small temporary tanks with just HOB filters, an air stone and controlled natural light coming in the window behind the tanks. The plate coral has retained its color though out all of this. In the temp tank it would go from completely flat to so inflated that it looked like it would pop! It has now been back in the display tank for a day and a half and it is looking fine. In fact, all of the corals are doing good. I have just one goniopora that is a little slow in coming back out.
