So.....
I don't see any additional overt signs of ich and/or velvet (in terms of spots/dots), though I'm keeping my eye on the foxface since his belly may have a dusty-looking patch. It was really hard to tell this morning because he was swimming around quite a bit.
Now, for the bad news... all 3 of my wrasses that are in the copper (my exquisite, flasher and orangeback) are simply not doing well. They are breathing heavily at the bottom, haven't been interested in food, and are generally looking really stressed. The orangeback was "swimming" around the bottom of the tank without even lifting itself off the bottom. He was basically scooting along.
I keep reading that wrasses do not fair well in copper. That's why I had opted to treat the leopard wrasse separately, since she's apparently even more sensitive than the others.
I'm wondering what I can do to improve the situation? Should I try to lower the concentrate of the Cupramine? At what level will it still be effective? I've read that it can still be therapeutic at .2 (I believe this came from the Seachem website directly). Is this correct? I'm fairly concerned that I'm going to lose my wrasses at this point. I'm only 5 days into the treatment, and they are already looking like this.
What if I were to pull out the copper with carbon and try paraguard instead? Is it any gentler or would I run into the same problem regardless?
The other fish seem to be tolerating it without much issue (at least thus far). The problem is that really, the wrasses and the foxface are the centerpiece of my reef tank - other than that, I have smaller background-type fish. I wouldn't have much to look at without the wrasses, and I picked out some of the most colourful ones for this reason. It's hard to get much of a fish selection in Canada, so replacing them would be difficult, and I will be devastated in general if I lose them since I'm fairly attached.
Any suggestions?
