Are they known to grow in colonies? I can't upload any of the HQ pics I have so it's hard to show that there's 4 distinct flattened football-sized lobes to it. Can I post links from external image sources?
After all of these years, I honestly haven't seen it in the dark. It's unfortunately not open to the public 24/7 and our service hours land us there 11a-2p at the latest. We're actually installing some long-awaited Radion XR30s next week, the left T12 VHO ballast is failing on us and we're finally out of bulbs. Should be able to get some more vibrant pics soon.A picture of it closed up would be helpful, but I know that may not be practical and whoever is maintaining the system understandably may not want to disturb it. You should be able to post links to external images depending on the hosting sight.
Do you have any suggestions for the light acclimation? I was going to start it out in the 25%-30% range. I'm not certain on the PAR level of the T12s and my experience with LEDs has mostly just been in the last few months. Figure less is better to start, then use the acclimate function in the mobius app over a month or two to raise ~10%.Looks like a big maroon, is she as old as the coral? These are guesses but not many corals have such large valleys with multiple polyps (mouths). But besides Acanthophillia maybe a very mature Trachyphillia, Mussa, Symphyllia agaricia or erythraea or maybe Lobophyllia flabelliformis.
I would be very careful changing out the lights and at least initially matching PAR. Corals have decadal memory and a big change even if other specimens of the same species do well.
