So I’ve never owned a wrasse before and decided to order 3, a royal flasher, carpenters flasher and Mccoskers flasher. The royal flasher was doa and the carpenters looked rough and ended up dying shortly after. Didn’t realize until after I got them and did some googling they usually don’t ship well. Mccosker is doing awesome today! My question is are there any diseases or parasites that wrasses are prone to? I saw somewhere that they can carry velvet without showing symptoms. My qt procedure is to leave them in there for 4 weeks no meds and just monitor (I’m in Canada so it’s almost impossible to get meds for fish) I do however have copper power but that’s it. Appreciate any help!
