Very strange A.hyacinthus growth

[Buran]

Hello from Italy,

I am asking here if you have any experience of this strange growth in my 7-year old A. hyacinthus that developed, during the last year, a totally white new branch.
Here are some pics.
Any idea??

Looks like a different coral grew off the rock behind it. Is it definitely part of the hyanthicus? Looks like different growth and polyp structure. If it's part of the table, you have my attention! That would be very odd for sure. Any pics of it where we can see the base?

Yes, definitely sure it's a part of the hyacinthus...here you are a pic of January, you can see where it started from...

That's odd, you should frag it and see if it propigates with the white color. No clue why it would do that, was it damaged there at one point?

No, no damage at all, the place where it is has not been changed in 7 years...

No one had similar experience???

Is it, in your opinion, the same Acropora? does it have the same corallites shape?

Look here, that is the same animal

yep :bounce2:

You have got to frag a piece and keep us updated on what it turns into! Very cool.

 

[Buran]

To tell the truth, I would avoid fragging this animal, I have never done that in 7 years...

Just snapping a small tip off won't hurt a thing. Sometimes fragging a large colony is good for the coral. I understand how you feel but if your as interested as we are about what is going on, fragging to regrow the other portion would be a huge help at figuring out what is going on. Either way thanks for sharing and I hope someone can shed some light about what is going on.

 

[Buran]

Ok, thanks, I will have a better look to see for a small branch suitable to be fragged

This is crazy!

Hoping someone can shed light into this issue...

How much growth have you seen in this coral over 7 years?
Have you changed any additives lately? Added anything new? Changed flow?
To me, it looks like that extremely rapid (and often pale) new growth that corals sometimes have.
But, having said that, the whole structure of the new growth is totally different from the mother colony. It is very very cool and interesting.
I see less extreme versions of this when a frag is added to a system and the original piece does nothing but it begins to grow a new section which grows like crazy but looks very little like the original piece...
I'd frag a piece as well and see how it grows somewhere else..

The coral has a regular growth, 7 years ago started from a frag (see pic) and during this period no changes have been done in my tank...
