Green Star Polyps?

[chickenofthesea]

These "Green Star Polys" have a white mat. From what I have read GSP have a purple mat. Is this GSP with a white mat or something else? I know its a crappy small pic but its the best I could do.

Looks like GSP in medium lighting. They brighten up in high lighting

Looks like GSP to me. Here is a pic of a colony growing on my overflow. http://i227.photobucket.com/albums/dd219/dwhooley/Oceanic 58/IMG_0667.jpg

hey dave, yours are really white like mine use to be when I got them. Then the Polyps turned green and the mat stayed white.

Herefishyfishy, What do you consider medium lighting? I have these pieces under a 250MH 10000k supplimented with two 15w t5 Actinics about 12 inches below the surface. The MH is about another 9inches above the surface. All insight is appreciated.

Anything less than the sun?:yo:

Seriously, was from the pic. Sounds like you have excellent lighting. Perhaps one of the whiter mantle GSPs though much nicer than Dave's undesirable invasive infestation :fish:

Though a long trip, if you are ever in the area, can give you some of my purple mantled GSP

Yessir. I have a rock full of it. That stuff grows like a weed!

BTW...my GSP is high up in the tank under a 4 bulb T5 fixture.

Awesome, good to know what I have is sufficient. Thanks for the offer! Not up that way all that much but if I find myself that way I will let you know for sure.

The problem is you lack Actinic Power to out drive 10k (yellow peak)~next time try 12K Reeflux. I have a rock that is simply electric neon green w/54w ATI Super Blue and its 36" from the lamp.

Hello,
There are several species of GSP (the down side of using common names) the most common being the bright green Pachyclavularia violacea. Other species can be white or reverse green centers of the stolons and white polyps. Changes of lighting will not affect the colour of these differences as they are genetic. High output florescent lighting or equivalent is the best for this type of coral for polyp extension and colour. There is another Genus Briareum of which some species are very similar to Pachyclavularia. Briareum sp. generally have a very light purple/whitish mat. There is some debate concerning these two Genera as to whether they are really separate or related as some species are nearly identical. One of the differences I have observed is the formation of tube like projections in the Briareum sp. while Pachyclavularia sp. remain mostly flat and encrusting.

Regards,
Kevin

If you are ever in seattle and want some purple mat gsp, I have a bunch. Free of charge

Thanks jrgilles! Awesome pic BTW Aquanaut!

also, please keep in mind that better flow will bring the polyps out more, they like to wave in the water flow
