Corals and cold temperature

[Koty]

As the (very mild) winter in my country started. My tank temperatures are 22-23 C. Corals seem to be much happier than in the summer where it was 25-26.

Hmm that's interesting. I had mine in the past at about 79-80F. I have since lowered to 76-77F. I haven't gone as low as you, but i would agree, a bit colder and mine also seem happier
