      White mucus on barbel

      I noticed about a month ago that two of my tosai had developed a white fuzzy mucus on them. The Chagoi has it on it's right barbel, and the Gin Shiro Utsuri has it a little more severe on all of it's barbels and I think on the tip of it's mouth, as well as something on it's tail. They are about 4" so it's really hard to observe or to take a good photo.

      Anybody ever seen this on their fish before? Is this some type of bacterial, fungal, or parasitic infection in-the-making...or just "plain old carp pox"?
      The water temperature has been rising here in the bay area, and it's usually around 65-75F.

      When I got it earlier this year, the Gin SU had proven to be quite a problematic newcomer during the treatment in the QT...developing unexplainable white spots on it's tail and dorsal. Encysted form of anchor worm, ich, or carp pox; I don't know what it actually was but it was all gone by the time it joined the main pond.

      Again it's been like this for the past month so I'm wondering whether I should pull them out and perform a shotgun treatment or leave them be.

      I really can't see anything on the shiro, but on the chagoi, I think that what I see on the barbel is SAP, a form of fungus, best treated with Proform C or equivalent. I also see what appears to be a thick slime coat giving a hazy appearance to the fish. This is often the result of parasites, and again Proform C, 3 doses, 3 days in a row, with Prazi or Fluke M mixed with the third dose is the preferred treatment.

      I moved these two, along with a Ginrin Chagoi into a hospital tank but unfortunately I lost the Ginrin Chagoi & Gin Shiro Utsuri...

      The first death was the Ginrin Chagoi which occurred on the night of the first Proform-C treatment. Right after dosing the tank, all 3 of the fish acted very unhappy; either heads up/tail down at the surface, or belly on the tank bottom with fins clamped. This was the first time I've seen this kind of behavior. Once the blue water went away, the 2 started swimming normally, except for the Ginrin Chagoi that was gasping for air at the surface. After 12 hours of the initial dose, I figured the effect of the medication would be gone by now but still heavy gasping so I decided to change out 75% of the water. However while siphoning out the water the fish just stopped swimming and was belly up on the tank bottom(still breathing). I continued on and completed the water change, and held the fish where the filter's current is for an hour but it died...
      I regret not changing out the water much earlier, which could have possibly saved it, but the biggest regret is treating this fish in the first place. The reason I added this Ginrin Chagoi in the hospital tank with the 2 fish shown above is because I noticed a slight mucus type of material attached to the edge of the pectoral fin. I have a Doitsu Kigoi that showed the same exact symptom but I left him in the pond and the mucus was gone the next day.

      Second death was the Gin Shiro Utsuri which occurred on the night of the third dose(followed with Hikari PraziPro). Again several hours after the dosing, this fish exhibited the same behavior that the Ginrin Chagoi did before it's death.

      I'm very saddened and disappointed but I would like to possibly know why these two may have died. I've been thinking over the possible causes...
      The first possibility was the Proform-C itself. It's been opened exactly a year ago; however I just treated 8 new fish(Koi & Goldfish) without any problems just last month, and there was no separation in the chemicals so I'm ruling this out.
      However I have to note that during the treatment of the new fish, 2 Koi developed cloudy eyes after the 3rd day. After researching online, I read others have experienced this oddity after the Prazi combo. Ultimately the eyes cleared up around the 6th day.

      Second possibility was the lack of aeration(hence the gasping). The tank is heated at 75F and the Ginrin Chagoi was roughly twice the size of the other two, but there were only 3 fish in the tank and again I completed treatment of 8 fish in the same setup, with the biggest newcomer being slightly bigger than the Ginrin Chagoi.

      Third possibility was ammonia/nitrite poisoning. Although 100% of the media in the hospital tank was just taken out of my cycled main pond's filter, there was about 2ppm of ammonia & nitrites in the water at the time of death. This is due to high levels of chloramines in our tap water, but since the dechlorinator I use is Seachem Safe, this shouldn't have been the case. Both deaths occurred within 12 hours of fresh water being introduced, which is within the time slot of the binding window.

      Fourth possibility was the dechlorinator & medication combo. Although I have treated all of my fish numerous times, this was the first time I used Seachem Safe since I was out of Prime.

      And finally, could it just have been the stress of the whole ordeal? I always shotgun treat new fish, and before/after Winter and there was a massive die off a few months ago from chloramine poisoning when I left my family in charge of the pond, and I had to retreat the herd just weeks after the Spring treatment.
      So this is about the 4th time these fish have been treated with medication within the past 8 months. Could I have been over-doing it, which ultimately caused the two to die?

      If the white stuff was indeed something treatable with Proform-C, I was expecting it to go away within a few days but it didn't get better nor worse. Does sap/fungus still take a few weeks to go away?
      Whatever it was, the Gin Shiro Utsuri had it pretty bad on the mouth(aside the tail) from the start, which was difficult to see from above but easy in an aquarium. Could it have been mouth rot?

      You got after it with the wrong chem. Get at it with Methyl blue.
