First RTD

I had my first experience with RTN. These four small frags were place in different areas of the tank and all four RTN within two days:( . I know this is contagious so is there anything I can do to help prevent it from spreading to another coral?

This brown "spots" was most likely a type of jelly infection, which then could have lead to rapid tissue necrosis.
I've lost dozens of corals due to Rapid tissue necrosis. My most recent event was from a beautiful A. polystoma, which happened to get RTN right in the middle of the branches. In result, I had to frag each branch off the colony. Luckily, those branches seem to be doing fine. From my experience, wild colonies almost always get rapid tissue necrosis in less than the first year of being introduced to your aquarium. Besides wild colonies, Acropora and Pocillopora seem to be prone to rapid tissue necrosis, unlike corals such as Montipora sp. The corallites of Montipora are inside the skeleton, rather than outside. By having these inward corallites, it protects the coral from getting many diseases. I once lost a lovely captive raised frag of a purple A. hyacinthus (table acroporA) with electric green polyps in less than than 30 minutes due to rapid tissue necrosis.
Out of curiousity, has anyone had any experience with placing superglue over the RTN'ing area of a coral? Has it worked? This may be something I am willing to try.
By the way, I would highly recommend reading this article below:

Nut,
Are you using any kind of dip before you add em to your tank?
Were these shipped tank raised frags or frags you got locally?
Did you cut down the time the lights were on...I have found this to be the biggest problem.

Yeah I did all that. To my knowledge they are tank raised (from GARF). This is one that showed up with dead spots so I cut off the dead spots, that's why they are so small. I attached a pic that was taken before I fragged it. The thing is they were in my tank for 2-mo before they RTN and they were showing growth.

Well, Graf isn't high up on my list of places to order from but since I live in So Cal I don't have to MO anything. From your first post, It sounded like these were 2 day old frags. I see now they were 2 months old.
I've never ordered from Garf and never will. From what I have read and heard from a few people I know who have TRIED to visit their "establishment" its not the best place.
What kind of dip are you using?
If the frags were mine, I would start chopping them above the RTN....

I'm not using a dip, for some reason I read drip in your first post :eek:. Anyway what is the dip for? It's to late for fragging, they are completely gone :(.

Sorry to hear about your frags. Its a bummer to have em two months and then this. If it were 2 days it would probably be easier to take.
As far as the dip goes, I use Kent's Tech D, it seems to work pretty good.
