I've got a piece of monti that started brownish red and now it's fluorescent pink. I've been working on some nice stylo for a while too that's starting to look promising. It started out completely bleached but now it has colour back to it's tissue and some of the skeleton's starting to pink up too.
I think part of the whole problem of SPS browning out is that lots of people simply accept them to be "difficult" coral and continue "trying" sps in their mixed tanks. I think SPS do best in a specialist tank, just like most LPS do great in a "lagoon" style tank just for them.
Plus it seems most of the LFS's just don't care if their SPS dies off. I firmly believe that stores that let their wild collected coral simply die off without putting an active effort in their husbandry, and make the same mistakes OVER AND OVER, should be boycotted. In most of the stores around the city they just let the coral slowly die and rely on somone buying it before it dies in their own system. I don't think they realize they can save money by just keeping their in stock coral alive, versus having to order more coral to replenish the stuff that died in the store.
It's a vicious cycle. I'm guilty of it myself, buying that $15 piece of coral that's almost dead, feeling that I'm doing the right thing, nursing it back to health. The stores are getting their money back and they just continue ordering more coral to kill. I read about it in the books but working for an LFS I see first hand how the market drives stores to stock difficult coral only to have most of it die in the tanks before they get in a customer's house.
But that's my grumbling about work, take it with a grain of salt
. I have a feeling I might be stirring up some heated discussion...
