Prazi treatment question
- Thread starter xanthurum
- Start date
I would do it tomorrow.
Too late i waited and waited but after no replies i did the second dose. Thanks for the reply although it came to late i will be better informed next time. Nobody was showing signs of anything but I wanna be positive the fish are clean of anything before hitting the DT. I will not take any chances with this new tank. Next on the treatment is a full 5 to 6 weeks of cupramine. Any other medication suggestions while in QT I have no problem keeping everbody in there as long as needed. I am already planning on a full 3 months with the final 4 weeks being observation to ensure health.

Prazi can be well overdosed without negative impact anyway, in most peoples experience. So I'm sure they are fine.
re: other med suggestions - there are some internal parasite powder medications you can mix with food that take about 3 days to take effect. i don't see too many people recommending that though so I have always just done the 4 weeks observation (including TTM) and if they seem healthy I don't bother with those powders. Sorry I can't recall the product names but can find out if needed.
sounds like you got a good plan going!

While most fish can tolerate higher than recommended dosages of Prazi with the exception of wrasses you didn't OD the fish. Prazi, per Hikari, is out of the water after 72 hrs plus you did a water change...no overdose. How much of a nitrite dose did your WC cause? A water change is what we do to reduce so I don't know how it could have caused an increase. Also fish can tolerate nitrites pretty well to a certain point. I'm wondering if there wasn't something else going on with the angel.
This morning nitrite read about .10 an yesterday it was at zero prior to the WC. It has remained at that level all day so i just did another WC to bring it down. I figured the filtration would bring it down today but no dice. I removed my goldflake into a 10 gallon by himself with clean new water and his breathing is substantially better. All the others in the QT are breathing better since the WC I just did and I hope I dont get another spike. There was nothing else wrong with the regal, after he died he had red splotches on his face and that is a sure sign of nitrite poisoning.

What is your ammonia? A nitrite reading of .10 ppm may cause stress but is not lethal. Now if it was 10ppm then yes, that is lethal. Are you using anything like Prime in the tank?
Ammonia was zero and yes nitrite was above lethal .3 can be lethal and i types in the wrong number before it was about 1.0 not .10 I did use prime to try and help but the damage was done and the fish died. No other casualties thankfully but i did have to do another WC this time about 25 gallons just to bring the levels back down to a repectable level and the following morning nitrites were nearly undetectable again. I have no idea what spiked them to a lethal level in less than 10 hours in an established tank or why 12 hours later they were still elevated. Or why another WC suddenly jump started my biological back into gear. I actually suspect a new frozen food i tried thursday night i will thaw some out and test it tomorrow.

According to Randy Holmes-Farley's article on nitrites .3 is not lethal in saltwater fish. http://reefkeeping.com/issues/2005-06/rhf/index.php#tab2
There may have been something else wrong with the fish.

I thought I read someplace that most s/w fish can tolerate nitrites up to 40 ppm. It was ammonia, which occurred just before the nitrite reading, that probably killed the OP's fish. The "red splotches" on the Regal are indicative of ammonia burn.
The only other possibility I can think of is if the OP mixed an ammonia reducer with Prazi. Some have reported fish fatalities after doing that.

Something like Amquel or Prime. Useful for controlling ammonia (in a pinch) when not medicating.
Here is what went down, when i woke up friday the fish was still alive but died about 5 minutes later. I had no idea what to do and after freaking out and removing the fish i tested the water. Ammonia 0, Nitrite 1.0, Nitrate around 20, PH 8.2, Phosphate .25 or so. At this time I dosed prime according to the bottle for nitrite help and I went out and got lots of water in the event it came down to doing another WC but hoped my filtration would take care of it. At around noon I fed a half cube of brine just to see if the remaining fish would eat and they did. The fish were still breathing rapidly so i tested again and Nitrite had not changed.
At 7pm another test revealed no change in Nitrite so a 10 gallon was set up and the goldflake placed in it. I had about 22 gallons left and changed out the water in the 55 with it. All fish breathing improved and Nitrite was around .5 so I felt better. Next morning Nitrite was .1 and by the end of saturday undetectable. I wondered if it was the new brine shrimp cubes i fed thursday night and friday so i tested it.
This was a new cubed brine shrimp i have never used in all my years. The test went as follows
1 cup of RO/DI tested perfect
1 cube of brine shrimp
5 minutes thaw time then tested water used to thaw brine shrimp
Ammonia .6, Nitrite 0, Nitrate 0 but a big black bug looking thing was in the cube as well
My question is, is ammonia normal like this or not. Also is it possible something happened to my Nitrobacter that just couldt handle the nitrite that resulted from the ammonia in the food.

Just so I've got my facts straight...
What you are talking about happened in your QT, right? Not in the DT?
What do you use for biological filtration in QT? Or do you just do WCs and use Prime to control the ammonia?
You added Prime on Friday, and then dosed Prazi on Sunday, correct? Any WCs done in-between?

I've heard of this with Copper before, but never Prazi... is this really a problem?
I just lots some Chromis during QT right when I started Prazi and had dosed Prime/Amquel when they died... hadn't considered that being what caused it.
Yes QT, its a 55 gallon with 30-35 lbs of live rock. I know i shouldnt have LR but i wante it for bio and hiding spots. Aqua clear 70 and Aqua clear 10 plus 2 powerheads. Prazi first dose on sunday, WC and second dose thursday along with new food. Dead fish friday morning, water test and prime then another WC late friday.
I personally haven't had a problem mixing the two, but to be fair I've probably only done it a couple of times. However, I've read probably half a dozen posts on here where it was claimed all fish in QT died after mixing the two. Symptoms were eerily similar to mixing copper & Prime. Still all just anecdotal... but enough to make me shy away from doing it ever again. On the flip side, you can find a few posts where folks claim no ill effects after mixing copper and an ammonia reducer. So, go figure. :spin3:
Here is another curve ball, after the WC friday night i have not done anything except some light feeding. Since everything was good with the water i decided it might be best to do one more dose of prazi. Dosed a few hours ago and Noticed the fish breathing a bit fast so i checked and Nitrites have reared their ugly head again. Reading .3 currently but were undetectable this morning.
