LOL, that reminds me of my first job. I was working at my dad's cake shop and I had long wavy hair. I was at the counter but working in the till and had my back to the customers. This guy comes in and goes g'day love, can I grab one of those? I turned around and he went "oh s^it, sorry mate". We all had a good laugh.
So I recently noticed some white cotton-ish growth on my male BN, around his gills - started on only one side and then quickly became evident on the other side too. I immediately took some photos and went to my LFS who suggested its probably a fungus (i suspected this!). I purchased some treatment, and checked dose multiple times before treating his entire tank (about 2pm today). Unfortunately on this occasion I was not able to quarantine him.
Tonight (about 8pm-ish) I noticed this on my BN. Struggled to video it, but fortunately did eventually manage! I dont know how I would explain it without a video? (Converted to animated GIF for the forum)
PLEASE PLEASE help with a diagnosis and suggestions on how to best treat him? This does not look good!
