PraziPro: Adverse fish reactions?

[NexDog]

I dosed PraziPro the other day in a 50g QT that had 2 Foxfaces and a Potters Angel. The Potters Angel was very active but the next day I found hiding and not eating and its colour looked off. After 24 hours I saw no change so did a 24 hour water changed and turned skimmer and UV back on (Prazi instructions say turn off). It looks a little better today but still not 100% . Can this happen with Prazi? Are dwarf angels more sensitive to it?

I have had this happen to me once with a group of Bartlett's anthias and once with a juvenile Atlantic blue tang. However both times, the fish had not started eating and really settled in to the quarantine yet. I did a large water change and added carbon and purigen to pull out the prazi and then dosed it again once they had started eating vigorously. They did fine with it the second time around.

I think it may not be the prazi itself, but rather that those particular fish had a large parasite burden, either externally or internally.

After it happened the second time, I changed my quarantine protocol. Now I wait until the fish is eating very well and settled in, usually a week after they arrive, to treat with prazi.

The Potters was eating really well and 10 days into hypo QT. I hope it pulls through.

This may not be it, but to expound on what Gwynhiwy said, think of flukes like little blood-sucking corks. You kill off a lot of them on a small fish, and that leaves hundreds of tiny open holes for the fish to bleed out through. I've actually used two minute FW dips on fish that I know have flukes, just to kill off a portion of them each day, then hitting them with prazi - so that the fish doesn't have osmotic problems from too many flukes leaving at the same time.

Sounds like a good idea. I didn't see anything that looked like flukes though. I now see a pale patch on its side. Its not swimming well. I don't think it's going to make it.

I'm sorry to hear he's not doing well. Don't be too quick to attribute it to the praziquantel though. There could be, and likely are, other problems going on. I hope he pulls through!

UV destroys many medications. Most but the most stable like Cu.

UV is a catch-22. Once infection has established on a fish and medication is needed, UV cannot be used with that fish, in general.

Have you considered ammonia problem. Has your QT (more precisely the filter medium in your QT) been well-cycled?

Any medication's impact on nitrification bacteria has to be well-considered.

The 50g QT runs 24/7/365 and has LR and sponges so it never has to recycle. The fish seems to be doing better but now has some finrot and some whitish stuff on it. Can't really make out if its fungal or bacterial so I dosed Melafix for now. I'll do Pimafix next week if it makes it that long. I'm 2 weeks into the QT cycle currently.

I believe I had this happen to me. I treated my Naso Tang for flukes. He started looking better quickly, but them within about 24 hours he had a lot of discolored dots all over his body and has not been doing well since.

Is there anything that can be done to help out? He is not swimming much and seems to have pretty rapid gill movement right now. I treated him 4 days ago.

My Potters didn't make it....
