How long did that change take?

I'm trying to find out more accurately, but the "blue" photo was taken 08-20-05 and the "red" photo was taken 12-10-05; so sometime within four months. It's in one of my friends tanks.

My understanding is that color relates most to lighting levels

That's my experience with Goniopora. The intensity of light effects the production of fluorescent proteins. More light = more FP. The increase in FPs increases the bright coloration in the green and purple species, but a change of light temperature hasn't produced a change in color spectrum. I haven't experimented with different color temp over my tenuidens yet (just intensity), but I do have a different purple species that showed no shift in spectrum going from 10k to 14k. The red goniopora species that I have do not become more intensely red when exposed to higher intensity light, they just fade toward a pale color (toward being bleached).
I feed all of them with cyclopeeze and I think if astaxanthin had any effect on FP coloration within the corals, it would have been seen by now.

disclaimer : Very bright Goniopora does not always equal very healthy Goniopora.

what do you think of this one,I'm thinking of purchasing it:

Run away!

Poor coral.

When I bought the blue gonipora, I got it home and put it in my tank, and it looked purple under my PCs. Just yesterday I upgraded to a 175W Mh, over my 29G tank, with a 20K bulb, and now the goni looks blue again. So thats cool. But I am concerned about him though, cause he hasn't come all the way out yet. Some of his arms come out a little ways, but he hasn't fully extened yet. And his heads are a little different. He doesn't have tentacles around his mouth like other gonis. I think that it must just be a different species of gonipora. Here's a question on a different subject, is cyclops the same as cycolpeeze, or is it totaly different?

Thanks John Kelly and sorry I messed up your SN,I was on my way to buy it-your post stopped me.

But it wasn't noticeable when it first got into that tank?

No. The owner said that it took several months to change color. It's an interesting adaptation. I would guess that in this instance a certain wavelength of light caused it to change and not the overall intensity, but it is usually the intensity that causes fluorescent colors to be more or less saturated.

This is the same "Purple G. tenuidens" that I posted above (2nd and 3rd photo), but after having some shade placed over it. The polyps became more tan colored and the purple slowly disappeared from the tentacles; a normal adaptation to lower light intensity.

It's bleached and looks like it got burned on top (too much light too quickly). It could revive, but it will probably just make you pull your hair out instead . Maybe if the store would give it to you for $5 or less.......

Very Rare bright yellow LIVE Gonipora coral!!!!

It is amazing how many people try to dish off bleached and unhealthy Goniopora as "Very Rare". Granted, some sellers don't know the difference, even experienced ones sometimes, but others....they are just dishonest.

here's my yellow goni.

 

[calvinkaren]

That is a very interesting color. I hope those are real colors for the coral. Nice Pictures.

 

[kimoy]

these pictures are not edited. the first one is under 20k halides and 10k pc plus 4 03 actinic pc. the second pic is all under the actinic

Unfortunately it is bleached.

.......with a couple of flatworms on it too.

 

[kimoy]

it looks bleached because of the light reflection. you have to see it in person to see the real deep yellow color. this is my second goni my other one is same as your but has a green tip and still growing after 4 months. here's a picture early in the morning with actinics on.

 

[kimoy]

i mean when the halides just turned on. actincs been on for an hour when i took this picture.

JENnKerry, still waiting for your gonis to drop a few more babies so I can get another or two from you. Let me know if any of them are dropping again. Thanks.

The yellow coloration is from fluorescent proteins. The reason why it is considered "bleached" is because the polyp tissue contains no zooxanthellae (brown) coloration at all (like your second one). Your Goniopora need at least some zooxanthellae; otherwise they will eventually die. Also, when they are bleached, they won't extend fully. Notice how your "bleached" one isn't near as extended as your second one?

If your lighting is too strong, your second one will end up looking like your first one in a few more months.
