why do these have no color?

[jennibee13]

im thinking they are zoas that are on bottom and not getting enuff light to produce algae and hence color up, but i have others on the bottom that are doing fine , even in the shade, 2nd pic.........

[jennibee13]

ouch , sry for oversize

some (many, actually) are just plain old brown. They may turn greener over time or in different light, but brown is very common.

[jennibee13]

sometimes one or two will show some orange but it dsappears after a few days

[seapug]

brownish-orange, I would assume....

try breaking a few polyps off and putting them higher up to see if it makes any difference.

Try a 20K blue halide. Most of the retailers use a 20K radium bulb to get the truely outstanding colors. While it does make the whole tank blue(perhaps more than appealing to the eye) it will color the corals up well. But remember that with a higher K rating, you lose intensity. So you get great intensity with a 6500K 175W bulb, you may need to step up to a 250W 20K bulb to get the same intensity but increased color.

Good luck!
Oh and on second thought, they just may be brown Zoas! Some dogs are just mutts!

what kind of lights do you have they should show a lot of there color under anctics too when the lights first come on
the name is pallie or something like that they have a longer stem and as stated before brown is a very common color

[jennibee13]

8 bulb t-5, 3 ati ab, 4 ati b+, and one ati super color

On a side note.....Looking at the second pic, I notice some aptasia that you might want to kill before it spreads and becomes a real problem.

[jennibee13]

well somebodys eating them, cuz ive never had them spread, i suspect my 2 pepps are having midnight snacks...............now look at this pic just b4 lights out, 3 of them seem to turn orange, could it be too much light?

[dogstar74]

those three are different species. The Brown ones are Palyzoas like was described before. The Orange ones are Zoanthid polyps. They can co-exhist as you can see. But they are different species all together.

I have no idea ab out the colour of your corals, but the cyano on the sand isn't a good sign......

Im not coral buff, if water parameters are out (as suggested by cyano) it may not be helping, or may even be the cuase.....

Just a suggestion - obvisouly assuming that it is infact cyano on your sand .......??????.........

[jennibee13]

all parameters are spot on, 4 yr old tank, it comes and goes, ive stopped worrying about it, so how would i go about fraggin this sort of thing, ive fragged a few of my sps, these seem fragile..................
