Hi friends- another Cory problem. This one appears to have a small white fuzzy growth on his nose. No other fish in the tank have anything similar. 0/0/20, 75F, 50% wc per week. The only meds I have are paracleanse and metroplex, and I have no ability to get more (Canada). I do have a cycled QT with a few random guppies in it. Sorry this is such an abrupt post it’s a crazy day and I just saw the little guy. Any advice is appreciated!
