SPS bleaching

[Anonymous]

Is it possible for a recovery if SPS bleach? i have a patch on a piece of brown monti dig that seems to have bleached, ive kept an eye on it and havent seen any spreading(bleaching) just curious if this is recoverable, i imagine it is, but im unsure? TIA

If you can still see tissue over the bleached area, than it can recover. If you see just the skeleton, than it might be downhill from there. You could try a Lugol's Dip to try and stop the RTN/WBD, or frag what's left of the colony. Only if you start to see it spread rapidly.

Yeah, might be a good idea to frag it if you can. In case it gets worse and don't recover.

If it has stopped spreading it could grow new tissue over the dead area. But if it spreads more I would remove the offending area.

I agree with A-buff-Doesn't sound like RTN. Make sure nothing has caused it(stinging nearby coral, mucus etc...)
It should recover under right parameters.

what would cause a coral to bleach? and by bleaching do you mean that its turnin white?

 

[badgergoth]

I think I'm right in saying that one thing that causes corals to bleach is when the temperature rises to about 30-33 degrees celsius. Many SPS expel their zooxanthellae around this temperature, causing the coral to turn lighter, and eventually die due to the loss of its symbiotic algae.

Any biologists know if this is a reaction to the zoos becoming denatured, or an oxygen-level trigger? Or something else?

The two main reasons for coral bleaching in nature are rising temps and intense sunlight. Other reasons are low salinity and pollution. Corals release zooxanthellae when it is either not producing enough or overproducing carbon energy.

There are literally dozens of strains of zooxanthellae that have adapted to numerous conditions of light, temp, location, environment, and species of corals. Since corals control the release of zooxanthellae, I always felt that it's ability to survive bleaching events will depend on its ability to maintain multiple strains.

This time time of year bleaching is much more common from the temp spikes.

A lot of people experence this also when changing very old MH bulbs or buying frags and placing the too high to fast.

Good luck with it.

Yep, "It's chiller time"!

my temp is normal just to let you know..my tank is in the bedroom with the A.C. and fans..i dont expect any flucuations in temp...my tank did fine last summer i dont expect any changes this summer it seems to be doing fine, no change.
