I’m not sure why people have issues with wrasse and prazi, I never have, and I’ve dosed it many, many times. Prazipro, with good aeration (not just circulation) dosed to the actual water volume of the tank should be completely wrasse safe.
I don’t see any other option, since the wrasse was flashing also. There are other anti-fluke medications, but I’ve had more issues the few times I’ve used them.
Well, the first time the aeration was definitely added after the wrasse reappeared. I'll give them a few days, then I think I'll dose prazipro if things start looking down again, but I'll leave an airstone in there.
