Are my Zoas dead?

ichthy · Mar 21, 2019

The small zoas haven’t opened in about 3 weeks
The largest one hasn’t opened in about 2 weeks

A few people have said they’re just extremely ticked off. One or 2 blamed my Coral Beauty Angel, Drew but Drew has been in the tank since March 6th and the smaller colonies were already closed.

For the weekend of March 8, something happened with the bulbs/wiring of my Coraline Biocube 29 gallon and my temperature went up from 77-80 and sat at 83 degrees. I didn’t have the white lights or the little blue ones with cooling fan, only the dark blue lights.
I got the replacement hood on March 18th.

Salinity as of 3/20/19: 1.024
Calcium as of 3/20/19: 424
Nitrite, Ammonia, Nitrate, Phosphate as of 3/20/19: 0
pH as of 3/20/19: 8.1
Alkalinity as of 3/20/19: 9.6

I think they’re fine. I often keep my tank at 80-81 degrees. It won’t hurt them as long as it doesn’t go higher. Just watch them.

I have been watching them and no change. I fed them once and they closed up and haven’t opened back up.
My temperature did go up to 83 degrees for like 8-10 hours (while I was at work) but that was due to some wiring/bulb issue in my hood and they were closed before that.
