only zoo's fail in my tank

[d_icemand]

So i have a jbj nano with stock lighting that i change every six months. I do water changes once a week. I dose iodine every 2 weeks. i have candycane, xenia, multiple hammers, frogspawn, a leather and some Ricordia. But when ever i add some zoo's, they never last. They always close up and dwindle away. Only partially open when the lights are on. So whats the deal? I keep them away from everything in the tank. It doesnt matter if i place them high or low in the tank.

advice please,

dave

I would try to keep them at least 6 inches away from any of your LPS. Also, some of those corals might release compounds in the water which are toxic to zoanthids...

What about the flow in the tank and other inhabitants like shrimp/fish?

When is the last time you tested your water?

the flow in the tank might be on the week side. The cleaning crew and fish seem real well and happy. I had the LFS test the water a couple of weeks ago ---PH was a little low but nothing abnormal. I have a lot of stuff in my little nano so something maybe stinging or killing it. I like my other stuff more so im not real worried about---just curious why zoo's cant make it. i thought zoo's were real hardy.
