Hey guys had a curious question that was having an issue finding an answer. I see all these awesome Acan colonies that grow out like a zoa garden. How do people get them to grow that way instead of in a ball? I have one that is looking like it will want to go in a ball shape but would like it to grow long ways. Is this just a let it grow and it will eventually grow along the rock type thing? I have a frag of some micros and the heads are growing around the disk but it was already flat when I got it. Thanks guys!
