I picked up a frag on Dec 1st via online from TCK. Coral arrived healthy - great polyp extension, but it was not as colorful in the pics. I've yet to get it to color up. Polyp extension is still good, and it seems to be growing, but it's just pretty blah as far as coloration goes. I also picked up a grafted sunfire cap from them on the same order and that has probably already doubled in size since I got it with great color. Any idea on why the Tenuis isn't coloring up?
