Hey everyone. I have a quick question(lengthy post, sorry)which hopefully an acan expert could chime in on. We had a major temperature spike about 3 days ago where the temp shot up to 86! I realized this late at night and immediately did what I could to get it down. Since then temp has been stable around 77. Some acans and my Duncan were under stress and were expelling some if their zooxenthellae but have since stopped so I'm not necessarily concerned with that.
After getting the temp down, I changed all RODI filters, did a 10%waterchange with brand new water and salt, checked my params as well as some other maintenance.
Parameters were:
Calcium: 480
Magnesium: 1480
Alk: 7.9-8 dkh
All tested with brand new salifert kits.
Anyways I did also however notice that a few of my acan colonies(3 out of 19 and only a few polyps on each) have had their mouths open more than usual, and a white thing coming out of their mouths and sometimes on the side of the polyps.
This white stuff, as well as he open mouths have only been occurring late at night, ~1 hour before my last set of actinics turn out for the night. After doing research I've come to believe that these are the mesenterial filaments, but I am really not sure. All of my acans are within a few inches of the coral next to it. And the only corals around them are more acans haha. All lords. So I'm not sure why they would feel threatened by essentially the exact same coral next to it. I have a handful of huge colonies touching eachother(practically overlapping) that aren't having this issue at all.
Any ideas?
Could this still be side effects to the temp spike even though it was a few days ago?
Would they send out filaments to attack hair algae?(I'm working on getting rid of that, and its not like its strangling them or anything)
Thanks to everyone who replies and/ or takes their time to read this lengthy post. I appreciate it.
