I got a montipora frag as a freebie from Aqua SD. It had nudibranchs and didn't survive. Looking at other Montipora on their site it looks like they have a bad infestation that has spread to all their montipora. Just a heads up to dip before putting in your tank. Everything else I've got from Aqua SD is great. It just seems like this is an issue they're having with montis.
