TSM Aquatics. I will never let a non QT'ed fish in my tank. I have had several QT tanks running at once. I just got tired of having all those tanks. I have purchased several high end fish from TSM Aquatics and they all arrived and looked great. When you look at their prices versus the cost to QT a fish and the pain that goes along with it, they are not that expensive.
I have bought a Gem tang, Purple tang, D. Sailfin tang, True Blonde Naso tang, Divided Leopard wrasse, Eightline Flasher wrasse, Pintail Fairy wrasse, Yellow Flanked Fairy wrasse, and a Orangeback Fairy wrasse from them.
