Can someone help me ID this bright magenta millepora?

I got it a while back from an LFS about 4 years ago. I grew fast to what it is in this picture and then drastically slowed down. It was always so vibrant and my favorite under LED. For about two months it's been turning bright highlighter green which is a shame and has not grown from this picture in over a year. The PE has been really bad compared to what it was years ago (very fluffy). I feel it's slowly going to die off...

It was a super cheap frag (like $20) from a trade in back in the day but I have no idea what it is. I'd like to hunt another one down!

We rarely give millepora enough flow and that is why it's growing weird and not in it's usual colonial structure. My guess is it never had enough flow and as your other corals have grown they are blocking even more flow.

Millepora is a shallow water species that gets a ton of flow, highest of any of the common species we keep. Due to being shallow they also receive a ton of light in the whiter spectrum and will likely benefit from a decent level of feeding and nutrients.

If you can't add more flow to it and concerned about losing it, the you might want to frag it and find a more suitable location. Like right in front of a powerhead or return outlet. I put mine on the edge of the rock work where it receives the most flow and is not blocked by other obstructions. Metaphorically, that stylophora next to it may as well be the Empire State Building next to a small ten story condo.

As for an actual name. I don't play that game with species like millepora and micromussa which can change colors in different systems or even different locations of a tank.

I mean at this point call it whatever Mille you want, since it didn’t come with one. For me, when I get hints of green in a piece, it’s maybe due to lower par, but the contrast looks good. If a piece goes completely green, it’s probably the wrong spectrum (ie. Too much blue) or it’s in recovery mode of some sorts.
