Corals side effects

[racoloish]

I use Seachem Paraguard to treat the display tank some fish and then I notice side effects on my corals. There were back to normal in less than a hour.

Are they going to be fine?

I'm not familiar with paraguard so a bump for your question. Your corals look pretty unhappy with it but their color and such is good......maybe just a reaction to the paraguard?
