What is this on the tetra fin???
Fungas and the other one looks like he has ich.
What would be the best thing to use to get rid of this? I did have them in my large community tank but theses are the only ones affect?
It doesn't look like a fungas more like anchor worm?
Might be. It's a bit hard to tell. Either way you want to quartine the sick fish so that it dosen't spread.
I have them in my spare tank that's fully cycled incase of emergencies like this all 4 are in there and the treatment has been added I have emailed the fish store to see if they can identify this
