Can sps corals recover from bleaching?

[artistreefer]

I lost some corals recently due to high temps and was wondering if some corals can recover. From what I have read the corals dont actually die but just expell their algae. Can someone expain more

Yeah, the first symptom is the zoos got expelled, but the trick is to keep it alive without the zoos. Most will not live much longer, esp., in home aquarium. However, some *do* recover from a slight bleaching.

Make sure you don't give up on the bleached SPS to soon. I have had completely white corals come back from the dead several months later. Hang on to them and good luck.

Of course, sometimes they die too.

They won't get much food from photosynthesis now. They can still eat bacteria and absorb amino acids from the water. However, you might want to consider feeding them with a very small zooplankton based food until they recover.

Good to know, I lost a couple of pieces. Is there any action that should be taken to improve the chances?... perhaps move them to a less intensely lit area or higher flow or .....

I can't isolate any one thing to suggest to increase the chances for recovery. I'd say just keep the same pristine water conditions that SPS require and hope for the best.

I probably would keep them out of high light for awhile.

I'd make sure they have good flow too.

yup they can come back. my digita was completely DEAD looking, but i started seeing bleached polyps.. then the color stated coming back, and now its growing as normal.

you will need to suppliment food. I like oyster eggs

Same as snowman. I had a digita do the exact thing it is now about 80% recovered.

I think it's important to assess if your SPS has gone through a tissue recession or a bleaching event... personally I've never had temp-spiked SPS bleach, they always sloughed off the skeleton and this does not recover except by new regrowth where the white skeleton is used as substrate for either new SPS growth or for other calcifiers. For those who've had them bleach but retain tissue, I like the ideas suggested. The leftover flesh can pull zooxanthellae out of the water and can multiply whatever is left over time to regain color, but if the tissue is nonexistant (you can still see it upon close examination if is there) you might as well break it off and plant a new round.
