I pre-ordered two tangs and a wrasse that were still going through QT, and on the day they were scheduled to finish I received a call from TSM saying the gem tang needed to be kept longer because copper levels had fallen below therapeutic levels their first week. But the rep I spoke with was also concerned that the gem I chose was too small to fit well with the larger sailfin I also ordered and suggested I take a larger specimen they had that was ready to go that was closer to the same size so that there would be less chance of aggression/bullying. Very pleased with the care that TSM puts into not only ensuring that you receive quality, healthy fish, but also that those fish will be happy in their new environment and work well with your tank's other inhabitants. All three fish arrived perfectly packaged and in great condition. Fat, happy, and accepting all different kinds of food right out of the box. I will absolutely be giving TSM my business again.
