Got this Falcula on Tuesday and gave it a Prazi bath. The Prazi did its job. What is the best treatment for the wounds left from the flukes falling off? Thanks in advance.
Welcome to Reef2Reef!
I think that lesion is something other than from the Neobenedenia flukes that you suspect. Neobenedenia are randomly spread across the fish, not in a vertical lesion like that. Was there a similar lesion on the other side of the fish?
I can't tell - in the photos, these look more like lost scales than dead Neobenedenia. If so, that scale loss is what is causing the skin lesions. That in turn is likely to be Uronema, that causes "deciduous scales", they fall off the fish when it is handled.
Trouble is, Neobenedenia *does* look like a bit like lost scales, so it can be easy to confuse the two issues. If you magnify the "scales" and see a round sucker at each end, its Neo, If you can see rings and no suckers, then they are indeed scales.
Hopefully it isn't Uronema, as in severe infections like this, it is always fatal (sorry!). It could be a secondary bacterial infection from the Neo, but again, it wouldn't be localized like this....
