Ok so my temp spiked up to 82.7 and I did not notice it untill after two days. Two kinds of zoas in two different places seemed to have melted away. One completly and the other still has a few polyps left. Then there is another one that looked frumpy but then seemed ok and five days later ( which is today) it looks closed up and clear jelly like. Is this what happens when heat spikes? All the rest of the corals seems Ok.
