I hate to say this, but it drives me nuts when people get on others for trying to keep "hard to keep" corals. Yeah, there are some idiots out there that just shouldn't be....But, if it wasn't for people trying, then we would never be able to keep these species in our tanks. Xenia was one of the "impossible to keep" species just less than 10 years ago. Now we have a hard time stopping it from spreading and give it away.
