Is it a good sign or a bad sign when the corals get all puffy when the lights at their highest intensity. I've always leaned towards that is a positive response
Lol. As a newbie, I was thinking about that too. My branch hammer coral swells when the lights are on and shrinks when they go down. So I would say it's not a bad thing. GL
Yep, you are right! It is definitely a good thing. They retract during the night and puff during the day to increase surface area for photosynthesis. Nice corals!
