Sick zoos??

[Murminator]

I have had 2 stes of zoos for about 3 weeks I had 1 up high and 1 on the sand. The 1 up high was doing good till about 4-5 days ago then they stopped opening, if they did open they over opened. The ones on the sand are doing perfect, so I moved these ones down to the sand yesterday no change. It looks like these were fragged a few times and the empty polyps are home to a family of brittle stars. There is also a peice of xenia grown on 1 of the polyps that I will remove when they are better. Could any of these be the demise of the zoos??
All suggestions welcome
