I don't have much, but funny that I saw this thread, because I just bought these today... They're not even really open yet, and I have no idea how to use my crappy camera, but hey... they're yellow:
Just opening:
Again, I have no clue how to use my camera, sorry for the crappy pics...
If you were looking for some yellow's, and want to trade, I 'm pretty sure I could frag this piece...
The polyps on this type are real small, and look like they might be the encrusting kind of zoa.
Like I said, I just got this piece, but after I'm sure it's safe, if you're desperate, I'll split it, just let me know,
HTH....
