Zoanthid color darken. not enough light?

[CaptNemo]

Hello everyone,

I used to have a 70W MH over a 20gallons High tank (aga). The MH is about 4 inches above the water. the color of bam bam zoanthids was bright orange. now i upgrade the tank to a 37 gallon oceanic tank with the high of 21". I also upgrade the MH to a 150W double end light. the light is now also above water about 4-5 inches. The problem is this. my green/pink tip frogspawn and my bam bam zoanthid's color is less bright. the bam bam is darken and frogspawn not as green. What is going on? is it becuase i just move them over the new tank? it has been is the new tank about 3 weeks now. or is it becuase of not enough light? What do you guys think? i am just keeping zoanthids , frogspawn ricordea, gsp, and mushroom. do you guys think those corals will thrive and keep the bright color under this 150W MH under the high of this tank?
By the way, in both tank, the zoanthids is about 5 inches above the bottom glass of the tank. the frogspawn is about an inches or two lower in teh new tank.

thanks.

zoos usually darken when they want more light as they house more zooxanthellae. move them up a tad and see if they regain some of their color over a week or two. don't move to high to quickly or they may become washed out.

Most likely stressed from the new conditions. Test all the water parameters you can and see if there is anything there. If not , keep the water quality right and they'll be nice again. I have zoas on the bottom of a 20xtra high and they are crazy with color. They just need to adjust. If you've found that in 2-3 more weeks they are not coloring, move them up higher gradually as mentioned above.

do you have the same kelvin in both bulbs and are they the same manufacture that could be why they seem a diffrent color
