Fraggin Colt coral and other leathers

[Matt]

Mark,
I've read that it is a bad idea to frag colt in the aquarium, but I've done it a couple of times, just took a scalpel-sharp knife in and slice-aroo. However, I've read that the elastic band or string method to choke off a section is preferred when fragging in the tank. It takes a day or two to get to the point where it falls or can be cut off without releasing any goo.
