The two doses of prazi should have been dosed 5-7 days apart to break the flukes lifecycle. I think I would focus on the copper and getting a good handle on that. I'd get the seachem test kit if you are using cupramine. You're going to want to test it frequently, definitely after any water changes, to make sure the level is holding steady at .5, and no lower than .4. Keep in mind, cupramine becomes toxic to the fish around .7-.8 so you don't want to overdose it either.
Im just about out of ideas for this yellow basslet. As I said in an earlier post, my LFS was able to get him eating again on formalin and metro. So I picked him up on June 3rd and put him back in quarantine, along with another clown.
At the suggestion of my LFS, I continued with metroplex for another week. During that week, he declined. He may have taken a bit the first day I had him, but after that, he went from coming out while I was feeding and not taking a bite, to not coming out of hiding at all.
At that point, again at the reccomemsation of my LFS, I did 2 treatments of prazipro. I saw no improvement.
I did notice his fins are pretty roughed up. So to treat for fin rot, I'm now treating with kanaplex . Im also treating with metro again for any possible internal parasites. Plus, that's part of what my LFS used to get him eating again, so might as well give it one more shot.
After two treatments of kanaplex/metro, the basslet has shown slight improvement. Instead of hiding all day, I've noticed him come out to swim in open water a couple of times. He's still not eating though. I'll do a third treatment of kanaplex tonight.
If he's still not eating after the third treatment, should I treat with a fourth? The instructions for kanaplex say to test for a maximum of 3 doses, so would testing with a fourth dose be detrimental to the fish? More importantly, am I putting the clown at risk if I try an additional 4th round?
In all honesty, I'm thinking its about time to euthanize this fish. I feel like I've thrown everything I can at him to no avail
