I have noted that the coral frags in my tank that have managed to encrust seem to be the hardiest and fastest growing. Is that my imagination? Furthermore, it would seem that some of my corals are taking forever to encrust, if at all. Although they may be growing up and branching out, they just don't seem to be encrusting. Is there a way to promote faster encrusting? If I had it to do over again, I would have removed most of these frags from their plugs entirely. The plus are unsightly and it seems more difficult for the coral to encrust of them (though that may be my imagination).
