Coral issues

[Helios]

My zoa keep dying. My trumpet, toadstool, duncan, and mushrooms are doing great but for whatever reason I can't keep zoa alive. I've tried them in different areas of the tank and with different water flows etc. Ideas?

How many zoas do you have? If your light is Marineland then that is the cultprit. Your other corals require less intensity while zoas needs more than what you have now.

Did you buy the zoas from the store or online?

there are hitch hikers that eat zoas look into that

Look for zoa eating nudibranchs. They tend to take on the coilor of the zoa they are eating.

Doug, that is one terrifying picture you got there

That is so funny because I had a few hitchiker nudis come in on floridaliverock just like those I left in the tank cause I thought they were pretty. I sold all that rock and have since started over but some poor soul out there may have them.

I'd do a dip on the zoas and see if anything comes off of them.
