copper power with Mccoskers flasher wrasse?

[joec]

30 days prophylactially should be ok, correct? They are not particularly sensitive?

Wrasses can be sensitive to copper I would recommend keeping it at 1.75ppm. I’ve done both 30 days and the 14 days then transfer into a sterile tank and myself and the wrasse preferred the latter.
