Polyp extension at night

[oneradtek202]

so i have noticed some of my corals dont have as much polyp extension as they used to at night. is this something to be worried about or just to keep a watchful eye? its only a few acro species that arent showing polyps (cali tort, baby blue acro) the rest seem to have healthy extension. hmmmm

what can polyp extension tell me about the health of my system

Hi Brandon,
Did you check the heat/temp sometimes that will reduce extension

hmm seems to be since ive hooked up my auto dosers that ive noticed the change. Perhaps the one colony is getting affected by its nearby anemone
