It seems that most of the zoo's reefer here uses fragging as the method to sprut the growth rate
I had a friend who has frags of zoos turning into colonies at a fast rate which causes it to be a nuisences. and not only one of them happen this maner...Its the whole tank of zoos growing this way..and the idea here is that , he did not even frag ...
so i wont agree that fragging is the only Cause of speeding zoos growth rates.
