Pink Colt Coral

A little reading will greatly benefit your future coral selections.

FYI, Colt Coral was the common name but a few years ago it's name was changed to Klyxum. It's naturally quite pink, which possibly explains why a little dye can make it look almost fluorescent. The real key to brilliantly colored coral is lighting. That's the advantage of using a pink/purple fluorescent tube for every 2-3 blue/actinic tubes.

At the bottom of this post I have added pics of how the real Klyxum looks. The lighting was 2-250W 14K MH and 2 VHO Fluorescent tubes, one Super Actinic and one Actinic White.  I've always been confused by that name Actinic White, since the tube clearly glows a purplelish-pink color, almost exactly like the plant grow tubes commonly used in freshwater tanks.

I was looking to see when the name was changed to Klyxum and found this article which was too good to pass by. I hope you find it helpful.
Renaming our Corals
Also found and copied here, is this tiny 2 post thread from 2006, mentioning one and answered by another of the geniuses of our hobby:

Klyxum coral ok with sps?
Eric Borneman identified my one and only soft coral as a Klyxum 
(colt). I realize that it has been only recently described as a separate
 species, however, I have been told that it is one of the  most "benign"
 of the group of colts.  I also know his standing about "separation" 
from soft & hard corals. I am wanting to add some acros in my 55 
gallon tank. Does the beautiful Klyxum have to go? I currently have 
monti's doing fine. Thanks!

			I do not agree that there is any big concern mixing hard and soft 
corals. My aquaria have always been mixed.  Perhaps it is because I use 
carbon that things are OK (although I have not always done so), or 
perhaps it is because there just is no true basis for such concerns, or 
perhaps it applies to corals that I do not keep.

That said, many people worry about chemicals reported to be inside of 
certain corals and macroalgae without much knowledge of whether they are
 released in any significant quantities, or whether equally concerning 
chemical;s are not present in other corals and marine organisms.

This article has a bit more on toxins in tank water:

If I were you, and I liked that particular coral, I'd certainly keep it unless  and until it seemed to be causing a problem.
