Any idea what happened??

I fixed the links for you. To imbed a picture you need to post the URL of the image itself (i.e., the JPG file). To find out what it is, you can right-click on the image itself on the photo webpage, select "Properties" and you should see a "http://somethingsomethingsomething.jpg" -- that's what you want. Ignore anything trailing past the .jpg extension -- you don't need or want that in the [img] ... [/img] tags.

Now. As for the pictures. Wow, that's nasty. I wonder if it's got a bacterial infection or something. The only thing that I notice of your parameters is that your SG seems a little high. It should be closer to 1.025. I don't think that's behind what's happening to your anthellia though. What is the tank temperature, any idea of the daytime/nighttime swings? (Temp, pH, ... ?)
