bleached corals
 

will bleached corals ever get their colour back?

Depends on the coral...and you have to know that it is bleached, and not just dead.

I had a frogspawn that bleached to almost being clear when it wasn't getting any light due to being shaded by another coral, once I moved it to my new tank it pretty much got all it's colour back in about a month and has never looked better.

mine r blastos and mushrooms. will they get there coulour back

I had some mushrooms that were on some live rock that I bought that were in heated saltwater with no light, they were pretty much clear and see though, now that they are under light again they have gotten all of their color back.

i have a little toadstool that bleached from some regenerated purigen in sept and is still totally bleached but looks totally healthy except the color

Yes, SPS will if you can still see polyps..otherwise its DOA

Spot feeding blastos will help keep them alive till they can recover
