If your a zoo freak, they are probably worth it. I just have an amount I dont pay higher then for a frag of zoos, so I cant see myself doing it. They are impressive though. A lot of people also have problems with darker blues staying blue over time, these being a different shade of blue may not have any issues like that.
They are going quick. I got some of the light blue ones and there were only a couple left today when I went. There are still a few of the other blue ones. They are a slight darker shade. They are all VERY cool. They also have some VERY cool wrases. All my fish died about 6 weeks ago so I am waiting to add fish, but I wish I could buy some of the stuff they had there.
Athen's Aquarium had some like that. I would have bought them but I have no money. THey were $28, light blue with a greener bouth, about 15-20 polyps on each frag, they only had 2 though and its been a couple of days, I'm sure they are gone.
