Another cory thread! This time I have an actual problem! So, I just did a big tank trimming and replanting after a period of neglect due to the busyness of my recent move. I ended up kicking a lot of gunk into the tank and I think that might have caused a bit of an issue with one of my poor corydoras. I looked in my tank today and noticed one of my corydoras that was flicking itself about and upon closer inspection noticed that its barbels were gone and its mouth was slightly white. I can't get a good picture at the moment but will try again later on. The white spot is not raised or fuzzy or anything like that so its making me a little unsure of the diagnosis. None of the other corydoras that I can see are effected similarly so as of right now its just the one.
