I bought beautiful purple milli and After 2wks it turns to green/purple now. the most green is on stem (?) and poylp ext is somewhat purple..

Same thing happens to yellow milli.

Why it is turning different color ?



They re growing pretty good!

Thanks

I have yet to see a true yellow millepora.....usually its yellow from shipping stress and wont stay that way in an aquarium. Maybe in a zeovit tank.....

Milleporas come in all the time looking great (often in two or three colours that revert to one) but they usually change.

Have had this guy for over a year and a half and no change in color. Has a hint of pink on its coralites. One of my favorites

Ive had a few millies change color on me and my thoughts are because of lighting / placement. I have a blue one (similar to palmers blue) and it looked tri color when i bought it under T5, pure blue now under halides.
 
I have a banana millie I bought from flyyguyy several months ago. It definitly has a bright yellow base, like lolgranny.

I'd like to see one with yellow polyps!!
Usually you get a yellow base with green polyps.
 
When I saw this yellow mille I absolutely had to pick it up! Yellow polyps and base, green tips. It's been in my tank for about a month, and the green tips have turned yellow also since. It looks like it has a green hue to it because of the blueness of the light, in person it looks true yellow.

I find all my wild millis go green then slowly change back. Not sure the reason. The only ones that haven't done this are ones that I nuked with light right from the get go.
 
Some people are color blind to certain shades of green which makes some corals look yellow to them. I know this from selling many green corals :).

Many acros will turn green when you change their environment. MAYBE they do this to protect their zooxanthellae? not sure.
 
Not sure where I picked this one up. It was a 1/2 inch frag that grew in well. Always appeared more yellow than green to me under 12K Reeflux.

Yellow coral under blue light will always have a tendency to look green, its a basic principal of the RGB model that allows you to watch color TV!

Thanks to my RGB Radion I was able to snag a pic under lower Kelvin light, and you can see this colony is a true yellow in my tank:
