The thing is, even with aquaculture, drawing any attention/attraction to this hobby is indirectly causing damage. think of the Noob who comes to your house or sees your tank here and wants some nice size pieces for his own new reef. Ultimately, someone who sees a mature colony in an established tank is going to want the same, and will be impatient about it. Why not buy the fist sized colony at the LFS
instead of waiting a year for the frag to grow?
I don't know how many people on here have killed corals, fish, and inverts to just say "oh well, it was only 35 bucks, I'll buy another one".
