I received a beautiful and healthy Masked Swallowtail (G. semifasciatus) angel that I pre-ordered a month before TSM was ready to ship out. After the long wait, I received an incredibly well packaged and healthy fish (huge box with lots of room for the fish to move in) that immediately took to my tank; eating prepared (frozen and flake food) within hours and withstood a very energetic group of fish in my reef. It continues to thrive several weeks later! TSM is an invaluable resource and retailer in our hobby. Their QT process cannot be beat and the quality of fish/corals/etc they offer get a massive head start to success in our tanks, and, we get a specimen that can be directly added to our tanks without weeks of QT. I'd buy from them without hesitation (only wish they updated their livestock more frequently!), especially if it's another semifasciatus!
