I had "wild caught" maricultured coral before and they lasted about 6 months then rtn'd and died while some aquacultured sps thrived and I still have them after 2 years. It's a roll of the dice with maricultured especially if its 1st generation, IMO. My local lfs doesn't get them in much anymore because the die off is too much but I would say dip routinely at first just to be safe. I had a 1st gen montipora that had great color and grew super fast, then suddenly rtn'd and died. When I took it out a gorilla crab popped out. He had survived the original dipping and had carved a home in the center of the coral and killed it. You just never know what will come with a wild grown coral.
As far as fragging them up and naming them...this is a funny subject for me. IMO, the popular thought around this is only named corals come from the big names in the coral trade. I say ******** to this. I see so many "named" pieces show up elsewhere with no name...ex: divers den posts a ton of maricultured colonies titled only with their growth characteristics that are posted elsewhere on the web with some goofy name for 3 times the price. There might be a few rare color morphs out there that people want to charge $1500 for a 1/4" frag for but I say they can have it. Like any hobby or industry there is always a niche carved out for the "ultra high end rare whatchamacallit" that people like to buy into just to say they bought it. If you want to frag up your coral and give it a cool name like Captain Americas Star Spangled Underpants then have at it. That's the beauty of a free market in a free country. "Murica!
