Meeting An Anemone's Lighting Needs, Blues Vs. Whites

How significant is "white light" to a nem?

In a nem specific tank, I'm curious as to what their specific light/par requirements are since I don't have to consider any other corals. Can they flourish under more blues with very little white? How much exposure do they really need per day? What works well for others?

Yes I bought a nice rbta from someone here about 9 months ago and it split last month.
I run 25% whites 75% blues.
Ah! I have about 6 in a nem only tank. Thinking I need to move them. One is so big he blocks all the light to the nems below him. Not sure if he is wanting more light, or if he is just selfish with it and doesn't want to share. I just set up another tank, so moving them shld be easy enough. Just curious about light needs.

Similar to coral, they’ll express different color under different light triggers. It’s hard to say what wavelengths will do what, color wise to a variety of nems. Bubble tips seem to be able to thrive in a very wide range of par. I had one parked in about 200 par for several years and it never moved. Tentacles were a little skinny though. Someone may come back with a contradictory experience, but I tend to lean toward higher light = more bubbly tips. Could be wrong.

Once you start talking about other anemones I can’t help never kept any others.

I think they would be fine! I would suggest feeding them especially in a nem specific tank :). Their colors will get better and better the more they are fed

Do you have them under T5 or LED's?
They are under LED's. They almost look like a giant lilly pad right now, gathered right at the surface and spread wide. One has bubble tips, another has the longer tentacles, and the remaining are in various stages in between.

Wow, that's interesting looking. I can't say I've ever seen them flatten out like that. I't hard to say if they are getting too much or not enough light. Are the two side by side the same kind?

They are both Rainbow nems, but from different originating tanks. The bigger one I just got about a month ago from a system buyout. The system hadnt had a water change in almost 2 yrs, had cyano (or maybe it was dyno) and a form of gha in the system. Was "faded", but has since colored up nicely. There are 2 I believe came from Travis' tank and the 2 smaller nems with all the yellow came from a hobbyist near midtown, oh and a green "intergallactic spagetti" anemone from Frank. all were under LED's in their previous systems.

So pretty, are those called rainbow nems? Nevermind, you answered it already

My light is programmed for a 11hr light cycle

08-0830am - 10% blue 0% white

0830-0900 - 90% blue 10% white

0900 - 1700 75% blue 25% white

1700 - 1730 blue remains the same, white decreases by 5%, but I increase red/greens by 5%

1730 -1830 90%blue 10% white

1830 - 1900 10% blue 0% white

1900 - off

Weekends I get super crazy and open the black out curtains and let the tanks bask in natural daylight for about 6hrs.

It may sound weird, but I don't run any combined percentages over 100% (i.e. 90% blue 35% white I would consider 125%)
