Prazipro Shelf Life

[ca1ore]

Havent used mine in a while, passed the smell test. Added some to a small QT and within an hour the 3 wrasses contained therein were lying on the bottom. Oh &#@$*; rapid water change and fingers crossed. I guess praziquantel does have a shelf life.

Wrasse can be very sensitive to it, i think I lost a flasher because of it, haliochearus biocellatus was fine with it.

Not sure about shelf life, but it should have an expiration date, right?

Do you have plenty of oxygenation? I know you have a large DT and many fish, I am not questioning your ability, just curious. How old is the bottle in question?

My wrasses always bury or hide for at least the first day of treatment.

Expiration date worn off ….. probably a sign that it's too old LOL.

No, no, not adding it to the main display, just a small QT. Turns out I am the idiot however ….. writing on the bottle is too small for my old eyes and I quadrupled the dosage. Ooooops. Fortunately caught in time and all three wrasses are fine and back eating again.

I was going to suggest possible OD. As I understand it, outdated Prazi is just ineffective, not dangerous. Glad everything worked out.

Sorry I made that confusing. I knew you were using in QT. I meant I knew you had successfully QTd several fish.

Uhhhh ohhhh. I'm glad you caught it quickly. I have never had negative experience with prazi and wrasse. So long as you beat the snot out of the surface of the water with a wavemaker so they have plenty of oxygen. Prazi drains it quick!

Ah ok. Yes the history of my fish is actually quite interesting. I took a break from the hobby for a few years. Got back in in early 2013 by buying a craigslist special. Always QT new fish, but I did not QT that tank. When I upgraded to a 265 later in 2013 I had an ich breakout. I assume it was there from the start. I always QT new fish because I don’t want to get something worse.
