What's wrong with my rainbow monti?

[Dylan]

I don't know what's wrong with my monti. Parameters have been dead steady for 3 months, lighting is 250w EVC 20k in a Lumenmax 3 reflector. It's about 20" away from it. 0 phosphates, nitrates. It started getting this white about a week and a half ago, and it keeps spreading. I have a pokerstar and a superman monti right next to it, and they are growing like crazy. Any ideas? STN?

Looks like superman monti.

Edit: looks like something may have fallen on it like some sand is all.

Doesn't look like a nudi was eating at it but keep an eye out for them

This is what they look like:

It's not a true rainbow, but the colony I got it from has the green center, etc. I did get some sand on it, that probably is it. I hope.

I've been watching and I don't think they're there, but I'll pay closer attention now. Thanks for the pic, I didn't know what they looked like.

that will happen to my montis once in a while for no reason, a lil sick spot, then gets better after a week or two. IMO it is that montipora is a sensitive species that pics up toxins or floating stinging cells from nieghbors.

My alk is steady, and the flow is moderate but random from a vortech on reefcrest.

Move it down, too much light. I have had the samething happen to colonies and when I move them to less light they are fine in about a week.

+1 on the superman

I have had my montis do some crazy stuff...the bottom of my orange cap monti which is a huge bowl is pretty much white. The top is still growing like crazy though.

Dont want to take over thread, but I cant get mine to rainbow...Had all the colors when I bought it...Params are steady, but no rainbows for me...Looks like a superman at the moment..Any tips?

Older polyps change colors over time. You might just have a superman. Mine actually is rainbow, I have a superman right next to it. It's just not a Tyree Rainbow.

Make sure you keep your mag level around 1400. Most montis don't do well with low mag.
