    SO, I made alot of purchases at fallfest.  To the tune of $700 dollars.  My question is, everything looks amazing, most things already looking comfortable in my tank, however, one of my corals, its a branching acropora, bleached in the bag on the way home, also, I rode with another member who also bought a acropora (we both bought them from the same vendor) and they both bleached!?!  Any ideas why or what we should do?  I don't want to bad mouth any vendors.  I emailed them instantly and havent heard anything back.  Any suggestions would be great.  THanks,

    Unfortunately it sounds like they sloughed tissue.. also known as RTN for Rapid Tissue Necrosis. I'm guessing the water in the bag was cloudy and possibly foul smelling when opened? If there is any tissue whether brown or colored you can either leave be and hope it stops (usually it doesn't on a frag) or cut above the white into good tissue to seperate it from the decaying part. With an average frag size it's easier said than done and still could very easily spread to the remaining piece. IMO unless you have a stable and healthy tank, corals that begin this process are better removed from the system and either quarantined, fragged, or disposed of. Leaving them in the tank can pollute/stress other coral that may otherwise be fine.

    So its 65 percent bleached. Partially still good color and part brown. I would rather removed it than have it kill anything else but its not totally gone yet. Your description was right on though of when I got it home. I did a coral rx dip. Do think I should remove it?

    Also do vendors typically refund this type of thing seeing as how I had no fault?

    Not knowing your system and if you have a seperate system. I would say you could cut the remaining portion that is good and either secure it somewhere safe for a few days or glue it to a plug with as minimal handling/stress as you can. If it continues up i'd say it's a goner.

    The only thing I will say is most vendors will offer an arrive alive guarantee on orders shipped, I don't know how they handle shows. IMO corals at shows can be quite stressed depending on the travel time and other factors in setting up. I guess you'll find out what they are willing to do.

    Good luck

    Yeah, like I said (realting to vendors) I am not trying to throw anyone under the buss. I am simply suprised because 2 corals from the same vendor did the same thing and everyhting else I bought is doing just fine. ANyways, thanks, I will be fragging it and hopiing for a recovery. Makes it frustrating since it was the second most expensive thing I purchased.

    Another thing also is that change is light will also stress the coral. So make sure to put them al the bottom ajust for your style or light. In my tank usually when I get new coral I dim both blue and white leds to half way.
