noticed you posted a few questions on coral growth,
it vary's from tank to tank, to many variables, equipment, light, feeding, cleaning, etc.. list can go on
looks like Nate cant keep em I know some people who have em and it grows like weeds... in my tank they grow but very slow.... I got a frag of em maybe a quarter size and glued to a baseball size rock... months later they maybe covered half the rock so far,
Another frag I glued to the back wall and guess what they melted away slowly same tank but in a different location
I have learned patience is key in this hobby, I love to take pictures about every month and look back and say WOW...
