got a small frag from Aquarium concepts.. really small frag took awhile for it to get comfortable in my tank now they climbing up the glass. I kindah like it that way it's easier to scrape and glue on a disk.
I thought those buggers looked familiar, I can attest they grow like weeds, just watching the foot how it stretches out man they don't make a mat as much as they stretch from point to point then grow to fill in the gaps. I noticed have quite a bit of green to them as well, made me think "Pink Lemonade Zoa"

Although the frags I did cut from the bottom of the rock are lacking green, perhaps it grows in later.
Seems to be a permanent change of color though due to the lights and not some artifact of fluorescence as ones I cut from under the rock (and yeah they grow more weedier than those ugly brown palythoas) don't have the green even when right under the same blue light.
