good waste of $40...but now that is too late...you already have it...now if you want any chance of keeping it alive, you need to first go read the ENTIRE thread of the Dendronepthyta (misspelled?) topic...it's around 40 pages, but it has guys with success with these. I'll shoot you the link later on...in the mean time, find out about reef snow...the theory is that these beautiful corals eat the bacteria that grow on the slime of other corals, the bacteria that eat detritus, so the tank needs to have lots of organic compounds floating around in the water column, thus causing a dirty tank,,,but the tank needs to be kept with low nitrates...good luck, and any help i can give let me know....the coral will slowly starve to death...it won't just croak, it will shrink very slowly, between one month and six months, but nonetheless will die, unless you've done lots of studying and are willing to do all the extra stuff to keep it alive. These things have been known to grow multiple feet in days-weeks, so there's plenty in the wild...but IMO, they should be regulated and sold only to those who are licensed to keep them...but that's another topic.
