Zoa warfare

[nick9one1]

I've got small colony of blow pop zoas that are close to nuclear explosion paly's.

I've noticed a paly encroaching into the zoa colony. The none of the zoa's now seem to open properly, and thy have changed to green!

Do I need to step in and do something?

I’ve never kept palys but I’ve had multiple types of zoa live with each other with no problem. Also, not aware of zoas changing colors. Following along...

Ive never had a problem with these two as neighbors

Could there be another reason the blow pops are changing colour?

I've had them for 8 months and they've always been this colour;

Now they look like this

I've got other sps, lps, and zoa's which are doing fine.

Bring down white lights a notch, add both peroxide and iodine to your tank. Should wake this puppy right up

I like adding iodine vials from prodibio. Melev’s reef has some YouTube videos on them. I bought some pale zoas for really cheap and brought them back to life.

Those zoas are probably "morphing" which is normal to most species. You can try to control that by offering different a spectrum or offering some carbon source, but keep in mind that other zoanthids in the system could also be affected "negatively" (at least at the same level in your point of view, similarly changing color) some how. Some times it looks like they are morphing, but they are actually bleaching because of some stress, like temperature too cold or too hot, etc.. So you have to make sure that's not the case. If so, time will heal the colony.
Be ware of those species of green Palythoa mixing with zoanthus. I would definitely keep them seperately.

My experience with palys and zoas growing into each other is that the bigger palys will win..this is happening in my tank with some purple monster palys that grew into some red zoas. The zoa colony has shrunk significantly, and the palys are continuing to grow over them.

You never can tell, but in my experience smaller, encrusting type zoas tend to knock heads with larger palys and eventually they will come to blows. The larger palys don't always win.

Local reef shop had a rock with over 200 heads of utter chaos growing next to a rock of some gorilla nipple type zoas. They got along fine until the zoas went postal and within a few days most of the chaos along the border turned grey and started melting..then the rest of chaos started doing the same.
