View Full Version : Metronidazole dosing
I have 2 motoros that are absolute pigs and eat like there's no tomorrow. I've had one of them for a year and the other one for at least 3 months. I think at least one of them has internal parasites (clear-ish feces), and obviously I want to get rid of them.
I see metronidazole (flagyl) being recommended all over this forum, but can't seem to find any info on dosing. I'm thinking I will dose the water because I can't be certain who eats what and such. How much to dose?
Noone? Everybody's using it but noone knows how much?

I do use it that medication for flower horn but never use it on my ray either. Rather then use that medication in water I think its best that you put that medication in the food and try to get Focus from seachem, mix small dose first and feed them. Ray is scaleless fish so dose in the water need to be less then scale fish.

If your rays had a parasite that was affecting them so much then they wouldn't be eating at all. It ain't broke so don;t fix it.

Hi i would suggest to use Tremazol(Raysafe) from Sera if its worms that causes the problems! Try to catch some fresh pooed out poo and get this probe under a mikroskope for analysis, thats the best way to find out 100%. Also coly from Preis is raysafe also against gill and intestal worms. Success.

i have dosed my flower rays with pure pharmaceutical grade metronidazole at the rats of 1/4 tsp per 40 gallons with no ill effects whatsoever! i have even accidentally measured up to 1 full tsp per 85 gallons and they didnt even flinch. metro is VERY safe. pick up some metro + by ARG. its sold under aquarium solutions. its very safe and has the dosing instruction on the label as well as a polymer that binds it to the intestinal wall. just maker sure during dosing that you change at least 50% of water everyday!
if you must... dose per intructions on bottle...
Could always use Prazipro by jungle as a preventative.

i have gone this route with the guessing games and IMO causes more harm than good.
i am pretty sure prazi pro is not made by Jungle

what do you feed? I feed shrimp often and the feces is clear/whitish often.
without knowing what the parasite is there is no sense in medicating.
Metro is very safe, should you find that you need it, 1/4 tsp per 20 gallons, daily for 7 days with 50% daily water changes before medicating.
My mistake. I ordered a bunch of Binox with Prazi the other week and confused the makers.

Problem with Metronidazole is that it can be hard on the kidneys. You would see a cumulative effect on the kidney damage. It wouldnt be on the first dose, but eventually you can see renal failure from using Metronidazole. Very safe for a single dosage to "clear out" the intestinal track, but prolonged exposure or repeated doses could prove fatal. Also, it does not dissolve into water as well as I would like. So mixing it into food would be ideal.
I feed mostly market shrimp. Once in a while they get salmon and beefheart (with garlic and spinach). They nibble on massivore, but never take the whole thing.
I guess I'll just stop worrying about this. I was just concerned about the clear-ish feces.

Sorry about the lengthy response time... BUSY BUSY here! =D
Here is a link for drug interactions, etc for Flagy: http://www.medicinenet.com/metronidazole/article.htm
Pay attention to this quote: "Metronidazole blocks the breakdown of propylene glycol in the liver leading to accumulation of propylene glycol in blood. Accumulation of propylene glycol could cause seizures, increased heart rate, and lead to kidney failure. "
Here is a link to a Bob Fenner post regarding metro and kidneys. I have also experienced this personally with discus, cichlids, and other fish.

I asked because I found many links to metro citing the damage caused to the liver ( in humans) but all the kidney problems seem to be secondary ( your first link) or anecdotal (your second link), however , your point is that metro has potential damaging side effects and should be used correctly and not be used too much, and I agree

Granted... you dont run into propylene glycol every day... but still... HEH!
