I want to add a few flasher wrasses (different species) to my DT (6'x2'x19") and have a question. I will be quarantining first in my QT, which contains 10 gallons of water (I think it holds over 17 gallons, but I only run 10). I realize it would probably be best to add all three wrasses to the DT at the same time, but that would require all three in the QT together and if something went wrong, I could lose 3 fairly expensive fish. My thought was to add one first, quarantining with other fish that aren't wrasses, and then maybe add two more at the same time later. My DT has a lot of rock... not exactly the proverbial rock wall, but close, and it allows for fish to swim front and backside with some holes that allows them to cut through. My question is, does adding these flashers in this manner make sense?
