Rose/Green BTA light requirements

[artarmon42]

I've got 12 BTAs in one tank. 3 are green, rest are roses. All on one rock island in the middle of the tank. The tank is lighted by 2 AI Vegas.

The roses all are healthy and happy.

All the 3 greens looked the same (healthy) when I introduced them to the tank (at the same time). 2 are now on the underside of the rock island (doesn't get much direct light) and they look fine. But 1 green which is at the top of the island, surrounded by healthy roses, seem to be bleaching.

I'm presuming from all this, that green BTAs require less light that the roses? Can anyone confirm this from their experience?

As I said, the tank is powered by LEDs, which allows me to set different percentage of different spectrums. Do green BTAs need more green spectrum? My current green spectrum is 10% (red is at 25%).

I'll be following along here, I have just introduced a GBTA and also use LED lighting. I am trying to get a light setting as well that the GBTA likes. If I bring the light intensity up too high and I can control the blue and white separately the GBTA will retract and then open up again after the lights go off, so I am thinking the light was too intense. Today I'm turning the blue down to about 30% and the white down to about 20% and we'll see how the anemone reacts. Some input from someone with experience in this would be greatly appreciated.

artarmon42, do you have any pics of that set up it sounds like it would look fantastic?

I'll have to take some updates pics.

In my experience so far, GBTA definitely seem to prefer much less light than RBTAs.

Still hoping for some input on spectrum, but my guess is that there probably isn't a happy middle ground. Not sure if RBTAs and GBTAs grow side by side in natural.
