    Uronema marinum:

    Symptoms - These are the red sores often seen on chromis damsels. The disease seems mostly confined to damsels and clownfish, but I have seen some exceptions to that.

    Treatment options - This is a very difficult disease to treat. Possible treatment options include: Metronidazole (ex. Seachem MetroPlex), acriflavine (ex. Acriflavine-MS), Chloroquine phosphate and copper. The problem is the fish can never be returned to the infected tank from which it came. Uronema is a “free living” parasite which does not require a fish host. So, going fallow will not eradicate it. Most fish seem protected from it via their natural immune system; but for some reason, chromis and some other fish are not always afforded this protection. Once a tank has Uronema, it must be assumed that the disease can survive in there almost indefinitely.

    Formalin bath or freshwater dip may provide temporary relief for Uronema.

    EDIT: A fish infected with uronema should also be fed food soaked with metronidazole because the disease can spread internally. Seachem Focus can be used to bind the medication to the food.

    Came across this looking for other info. Never having used any of the meds mentioned but also knowing enough that you shouldn't use them with live rock. What about the live rock and corals in a tank that has this? This seems like 1 of the worse diseases.

    Metro might eradicate the disease in a DT and there are reports that metro can be reef safe. I'm not certain of either, however.

    Let's take the not reef safe route. Since there is no fallow period, how would you rid the possibility of any hitchiking on coral and live rock? Curiosity setting in.

    Its a shame that there is only one way to test this theory. Not a happy ending if the theory is disproven

    It's being tested to treat dinos in this thread: https://www.reef2reef.com/threads/dinoflagellates-dinos-a-possible-cure-follow-along-and-see.253917/

    But I'm still hesitant to declare it "reef safe" as metro will target anaerobic bacteria, and could thus eradicate anaerobic regions of a DT. This would probably only be a threat to systems which utilize a DSB for filtration. Plenums also encourage anaerobic areas. I'm sure deep inside rock, anaerobic bacteria exists, but aerobic bacteria near the surface probably provides the bulk of biological filtration.

    I assume it would come to a point where finding the neccessary dose to iraadicate this disease, and if thay much os safe in the dt

I have ParaGuard on hand, can get metronidazole and also have CP ...should I QT him right away...he was QT'd for a month before putting him in the DT...that with CP...since he otherwise seems well, should I wait and observe or go for something...Help...

    @Congaken Can you post a photo, showing the red spot on him? Being it's a butterfly, the spot is more likely to be something bacterial than Uronema.

    Does it look anything like this? Maybe just not as severe?

    I would lean more toward bacterial as well, in which case it can heal on it's own or get out of hand. If it's gone already, that's a good thing but let us know tomorrow if it comes back or gets worse

    Well...the right one is gone, but there is a small one on the left side...odd, eh?...so lets see what happens...any antibiotic that will work in a fowlr with motile inverts?...If he needs treatment, I really hate to take him out unless no choice...do have a QT set up...but:confused:

    @Humblefish could you make the case to prophylactically treat all incoming fish with acriflavine and/or API general cure (over PraziPro) to keep Uronema from ever entering a system? Or would one acriflavine bath and two applications of general cure not successfully knock it out. I say this for those who don't have access to CP or have CP sensitive fish.

    You could soak an antibiotic (ex. erythromycin, kanamycin) in with his food, if you also used a binder (ex. Seachem Focus) to prevent the medication from leaching out.


    Treating with General Cure or just metronidazole (ex. Seachem Metroplex) would be a wise course of action for Uronema prone species i.e. any member of the damsel family. You can safely mix metro with most other medications.

    I have MetoPlex and Focus...so whatever the infection seems to be...I'll start a course tomorrow...of course, other fish will eat it too...the bf generally eats live little-necks and cyclops...because of his small mouth...which do you think will be best...other fish are chromies, Kole, firefish, Singapore, Niger and diamnd goby...
