Open Brain coral

[harlequin tusk]

I was looking at Diver's Den's selection of open brains and i noticed some were from Indonesia, and others didnt have their location listed. Are green Trachyphyllia geoffroyi from Indonesia better colored than green Trachyphyllia geoffroyi from other places? Also the green open brains under actinics look amazing, but when all the lights are on do these corals look kinda dull?
Thanks

My green open brain stays very green even when lights are on. The color looks amazing under 10k and 14k lights. I also use blue LEDs and not actinics.

I Have a Bali Green Open Brain, under Giesemann 14500k 250w, and, have a beautifull electric green, even under the HQI.

two hour a day, it is only on the actinic, really more beautiful, but it is still.

I have mine under and to the front substrate from a 150 watt Ushio 14,000K with four 54 watt T-5 actinics. Four blue LED night lights in my 60" Marineland Pro Lighting System.

How far apart should one three inch green and one three inch red Trachyphyllia geoffroyi be in the bottom substrate. The LFS had they quite close about a few inches and they seem to be doing well for a few weeks before I took them home.
