Uronema Question

[Shallow Planet]

Can a non infected fish carry this deadly disease? Or will it always show itself in QT if QT is long enough? Example could a tang carry it but be immune and than carry uronema to the display? My current QT protocol is TTM with prazipro and total QT time of 6 weeks for monitoring.

I'm a bit paranoid as I got a purple tang that was briefly in a tank with a chromis who had uronema(When i say brief I mean like 2 minutes before realizing the chromis had an infection). Am I good if it never shows signs over the next 6 weeks?

Thanks!

That's a troubling situation. Uronema is a free swimming parasite that does not require a fish to reproduce. So TTM does not eliminate the parasite's cycle. You can't starve it out of a tank either. Once it's in a tank it's in there until the tank is sterilized. Most fish's immune systems can resist Uronema parasites. But lately, we've seen some cases of Uronema showing up on fish other than Chromis. Not good. If it was my fish, I'd give the tang a 90 minute bath in an acriflavine product like Ruby Reef Rally. During the bath, I'd sterilize the QT and refill with fresh saltwater.

See below, Uronema is a tough one.

Thanks I just picked up some Ruby Reef. Should I give every new fish a bath to prevent from carrying something like uronema? Or is that unnecessary? All I give now is Prazipro before QT is done in 6 weeks.

I am inclined to add a 90 minute acriflavine bath to my QT process. Either during TTM or after Cu treatment during transfer to a new sterile QT. Easy enough to do.

Big fan of RRR. I like its antiseptic and antibiotic qualities for fish that are disease prone. Something to consider when QTing. For example, when QTing a Copperband Butterfly, I've added a bath in RRR and treating the QT with Nitrofuracine Green powder (NFG) to help fight off the all too common "red spot/mark" that once they show up on a CBB, it's almost too late to save the fish.
