Well guys its strange. If you recall I was having issues with my brown button polyps. They were closing up and looking like they were beating eaten or just were decomposing....shrinking away to nothing and then end up with holes in them and such. I did a freshwater dip on them and they appear to be doing better. I have a new colony of zoas and two small frags of zoas also. The new colony and one of the frags of zoas aren't doing very well. The frag rarely opens anymore and looks to be shrinking. The colony is opening, except the ones on the outer edges...these seem to be closing up and shrinking. The colony just doesn't look as full as it used to be and has several that just won't open. There are no white dots or anything on the zoas that would indicate zoa pox. I did a freshwater dip on them the other day, but it seems as there is no improvement in their condition. The second zoa frag is doing great, but the odd part is that it has one of the zoas from the other frag in it, and it is doing awesome, but one inch away the original frag is doing terrible. This leads me to believe it is not water conditions nor lighting since the same type of zoa is doing great and is located less than an inch away among another type of zoa frag. Does anyone have any suggestions or ideas as to what I could do to prevent further deterioration of the zoas? I'll try and post some pics later...thanks all.
