Well as you know Chad. I have (2) anemone. The first one is not very bright and never had the yellow tips (it was a really nice orange though). However from my discussions from the guy that i purchased it from in Parker(sean) he swears up and down it was purchased as an Sunburst anemone from Aqua Mart 3 years ago and he's had nothing but that 1st anemone that has split over and over in the tank so no mixing up. He has T5's and I don't think was ever good about changing them.
I am not much of a picture taker so stupid me I don't have any for compairison. However I sent that picture i sent you of my new 100% verified sunburst that i purchased from Ki next to his. His response to me was where is the one i sold you. After around 6-8 months in my tank it has DEFINATELY lost color. It is much more dark/dull...(regardless if it is/was a sunburst). He doesn't believe that the duller one is a picture of the one that he sold. So that goes to show you the distrust in this hoby about things like this. So if my new sunburst ends up dull and loses color after a year or so, what conversation do you think we will end up having then?
What I find interesting about that article is the following:
"LEDs seem to make the anemone loose its rich color and can even start to resemble a Lemon Drop BTA"
Lemon drop is more yellow, like yours is full on yellow under your LED's.
I've been told by Ki that the more mature they get the more yellow they get. So is it a combination of maturity of the parent anemone and lighting that gives it more yellow? One of the main things about that article is the fact that "This bad boy is ORANGE!". Not the fact that it has yellow tips...
Just a thought, but if we have Lemon drops and they are yellow...sunburst are orange with yellow tips. Maybe a lemon drop is a sunburst that has been kept under LED's for a long time...Sunburst is a lemon drop that has been kept under some combination of 20,000K spectrum with purple and actinic T5HO supplements.
So assuming that, maybe a rainbow kept under optimal lighting can fool people into thinking they are close to a sunburst. However once they go under LED's like in my tank they turn a less bright orange.
Disclaimer: not only do i run LED's, but they had been turned down really low. I'm slowly ramping up the lighting, but when i had the lighting up before I had some very upset zoanthids. This tank no longer has zoanthids that are going to be staying in it long term so i'm just hoping the euphylia can handle higher light.
