My Betta Oscar Mystery

Can anyone identify what that black stuff is hanging out of his gills or the bottom part of his head?? It appears the Ich we treated is gone after treating with API Super ICH treatment. Changed the water 30% and now I noticed this abnormal black stuff is appearing. Is it normal? Thank you!


Water parameters: 

  • pH 7.6
  • Nitrates 0ppm
  • Hardness 75ppm
  • Nitrite 0ppm
  • Ammonia 0ppm
  • KH/Buffer 40 ppm
  • Water Temperature 83%  (to help get rid of Ich)

I could be wrong but I think that's just part of his gills.  Can you put a mirror up and get him to flare at it?  Might give you a better view.

Or compare it to previous pictures of the fish if you can get them.  

If it was previously NOT there, that would be something to be concerned about.  Gill irritation could be ammonia.  Or if the ich treatment was an irritant, perhaps.
