fuzz on cory cat??

[whitetiprs]

On both fins of the cory cat there is this white fuzzy looking stuff, what is it. Though it was a fungal infection and treated with a combo of meta fix and prima fix and has done nothing. it was only on one fin now it is on both. No other fish seem affected and the cory cat act fine otherwise.

It does seem like a fungus from what I can see. One of my mollies has a similar condition, currently I am treating with Maracyn. But as I have been advised be careful and test your parameters often as it can affect the bacterial colonies. Maracyn and maracyn II are fine with cory's btw. I also recently found out that it is better to keep the temps down around 76-78, I had originally raised my temp as you would with ich.
