Cardinal Tetra strange Fin

[Joeriw]

Hi Guys,

I noticed one of my cardinal tetra's has a strange fin since yesterday.
It's white and looks very stif, not clamed to the body but fanned out. Like a piece of plastic stucking out of the fish.

Any idea wat is going on with it?

This tetra was part of a batch i got at a 'bad' pet store. a few of them where sick (Ich) so i treated them with Esha 2000 and Esha Exit for the last few days. Somehow this little guy still developed this strange fin. Most of the batch sadly did not make it, but now there are now signs of Ich anymore. (unless this fin is a symptom)

Water parameters are good, about to do my 50% waterchange later today.

The fin looks odd but it isn't a symptom of Ich. Keep up with the water changes and tank maintenance and just watch out for any other odd things.
