Fish died after Prazipro?

[mc-cro]

I lost a wrasse last night after dosing prazipro, but the other fish in QT are fine, I dont understand?

so here is the rundown.

10g QT tank, set up using bio wheel filter, bio wheels reside in my sump for quick starts of QT tanks.

4 small fish in Qt, 3 fire fish have been in there for 2 weeks, wrasse was put in last Friday. I dont normally mix in new fish, but I figured I would just extend the fire fish an extra week

water changes and siphoning of poo every other day, ammonia not a problem.

all 4 fish were eating frozen brine, showing interest in other foods.

The wrasse came in last week very stressed, I was not even sure he would make it the first day. laying up side down, labored breathing, pale, the whole nine yards.( He did have a white stringy substance from his anus, I figured worms.) Next day he was swimming, within a day or two he was eating.

The wrasse seemed to be getting stronger and more active, showing increased appetite. So I figured I would go ahead and do a round of prazipro. I made a mistake and was thinking it was my 15g tank and dosed more then the recommended amount, but not by much. a 10g tank should take appr 1/2 teaspoon, 2.5ml, I put almost 4ml. The 3 firefish were completely uneffected, showed no changes visually or activity wise. they still just swam around like no problem.

The wrasse clearly had issues with it. his breathing became very labored, he either layed on the bottom or swam verticle, and often went to the top for air. I did take him out of the QT and put him in a seperate container with no medication for a few hours, but the damage was already done. He did not make it through the night.

what happened? I dont think I OD'ed him on prazipro, I know I made a mistake and overdid it a bit, but the other fish are fine?

It's possible the wrasse was too far gone (with flukes) to make it. I've read once flukes reach the eyes, the prognosis is pretty grim. Also, wrasses seem to be more sensitive to just about any medication... I'm starting to notice a trend based upon anecdotal accounts.

 

[mc-cro]

I specifically watched for cloudy eyes, never saw signs of flukes in eyes. doesnt mean it wasnt there, I just didnt see it.

my unexperienced guess is that maybe the medication put a hurting on the flukes, and they spasmed in his gills, causing him breathing problems?

I really cant find anyone that has OD'ed a fish on prazi. I have read accounts of severe over medicating, and the fish had a hard time, but recovered.

but if wrasse are really sensitive, and in a somewhat weakend state, maybe thats what happened.

Newsmyrna80 understands the pathology of flukes much better than I do. I'm sure she'll be chiming in.

Some new fish just don't make it; I doubt it had anything tro do with PP.

 

[dominic]

not true about the eyes I have used it successfully when it has gotten in the fishes eyes before, make sure you aerate the top of the water when doing prazi also.

 

[mc-cro]

I understand the oxygen suppression. I am also currently dosing my main system ( I havent always done a great job QT'ing fish from other hobbyist) and I am struggling to keep the ph up, without running the skimmer.

IME, wrasses do not fare well if you overdose praziquantel. I experience a situation similar to yours -- I mis-calculated the prazi dosage for my QT and the wrasse reacted with listlessness and labored breathing. I realized my error a couple hours later and corrected with a water change, but the wrasse never fully recovered. He died a couple days later. Like you, I also had a firefish (as well as a royal gramma) that was completely unaffected by the overdose. That is the only time I have seen a negative reaction to prazi, so I am careful to measure the dosage correctly.

 

[mc-cro]

man, now I feel really bad. if the OD of prazi was really at fault, that really sucks

We all make mistakes. I killed three wrasses by administering CP before I figured out that they couldn't tolerate it.

+1 IME wrasses do not handle any overdose of Prazi. I've had the same experience...labored breathing and lethargy. I did a water change but it still didn't make it and this wrasse did not have a severe case of flukes. Ditto on the CP with wrasses.

I am reviving this old thread. My flame angel died yesterday due to my mistake. I dipped it in Przipro but I used a small jar thinking it will be easier to see any flukes. I also had dipped a smaller citrinius goby in the same jar and it did not have any problems. The flame angel did not make it past the night after the dip and putting in the DT.

believe Flame angels are also known for being a bit sensitive to medications. I know they are thought to be sensitive to copper but not 100% on what else.

 

[Rare Angels]

Most pygmy angels are sensitive to copper and it's use with them must be handled carefully. I haven't had any real issues with PP and angels though.

Yeah it's definitely not PP. I had PP for a few hours in the QT as well. It was lack of oxygen and I think that Flame Angles are not very hardy compared to other fish.

 

[Newsmyrna80]

Did your flame definitely have flukes? Angels do have a propensity to fluke infestation. As you noted it was more than likely an oxygen issue. Prazi is known for depleting oxygen.

This. Did you have aeration of some sort?

 

[tc2007]

Well in the QT yes, a good powerhead pointing to top and the HOB filter dropping water. Is that enough? My mistake was to do another dip in a small jar with no aeration of-course and on top of that, I wanted to make sure none of that water goes into the DT so I emptied all the water leaving the fish without it for a few seconds. But by then the fish was already starting to collapse. After I put the fish in DT, it sank to the bottom for a few seconds and then recovered and was swimming upright in place for a few mins before other fish were getting curious. After that it went to a hiding place and next day I found it dead. I proably wont get another Flame unless I gain many years of experience in keeping fish alive :angryfire:

I don't think the flame had any flukes or ich as it was not showing any signs. I just wanted to be extra careful.
