probablly better to let them grow out a bit, atleast to heal over. One thing I am learning in fragging is that if you let a frag heal over in the tank it was originally in, it will usually have no problems, but if moved to a new tank with diffrent parameters of any kind, you will most likely lose it.
Matt would most likely love a piece, myself I have a frag of that same blasto I bought from Rob probablly 3 months ago. I appreciate the offer though. I am sure if you wanted to be generous though that someone in Chico has something to trade you for a piece...
