Colt coral frag not opening up.

[dunc101]

Hey everyone,
I bought a colt coral from my LFS about 3 weeks ago. The colt coral was very large so I was able to frag it to get two out of it. Anyways, the original colt coral is doing great, but the frag that I made does not seem happy as it has continuously been "bunched up" and very purple while the original piece is more of a pinkish color and appears to be doing great. I am afraid I may lose the frag as it has not looked good for about 3 weeks now.

All of my water parameters seem fine, however.
Here are my water parameters:
SG: 1.025
ammonia: 0
nitrite: 0
nitrate: 5
Phosphates: 0
calcium: 420 - 440
magnesium: 1200
kh: 8

My lights are 6 x 54 watt T5 fixture in a 90 gallon reef ready tank.

Do any of you have any thoughts of what I could do to get the coral to open up?

Here are a couple of pictures:
This first picture is of the original piece of coral that is doing great in the tank.

And this is a picture of the "frag."

Do any of you have any suggestions on what I could do?

Thanks!

It is right around 3 months old.

I got a huge colt coral in my tank. Everytime I tried to frag it that happens. I found that if I put it in my fuge they heal and encrust a lot faster.


I also noticed that your rock is starkling new. Even though I frag on to small new rocks, yours seem new through out your entire tank. Just an observation.

Mine is doing the exact same thing two weeks after acqisition.:furious::hmm3:

The difference is that my tank is 3 years old and 320 gallons.

All the water parameters are good. Very good flow. Perhaps too much?

Near bottom of 34" tank. Have very high lighting 4 400W MH and 4-96W CF

Hey VictorE,
My coral FINALLY opened all the way up =). It took it a good 3 weeks before it was happy though.
