- A fast-moving white-fuzz often indicates Columnaris infection. This is an "opportunistic bacterial infection" that can be treated (if caught early enough) with a gram-negative antibiotic, such as API Furan 2, Mardel Maracyn 2 (minocycline), etc. Fish subjected to stress (such as transport to/from stores, being in plastic cups, etc) are susceptible to opportunistic infections, such as Columnaris.
