Update- the patch came off (couldn't find it in the water, but there was stringy stuff in the water). The stringy stuff seemed to be off the fins, too.
Because I just couldn't stand having him in the same water with that stuff, I did do a 100% water change (it's just a quart so not a huge deal), and he seems better. I don't see the stringy stuff on the fins anymore (but it was ugly and disturbing when it lasted!) (crossed fingers that it's over!)
In the process of the water change, I did see a bit of it on his betta hammock- I lifted it with a Qtip & examined it. It looks mucosal in texture, & was yellowish. However, he was in a green tea tannin solution, so I'm not going to over-interpret the color (ie: would ordinarily ascribe yellow mucus to infection process, but not necessarily so given the tea matrix).
Again, I'm seeing white tips (no damage, just color change) on his (largest) ventral fin, and on the rostral aspect of his dorsal fin.
I am also wondering if this is a case of sloughing off of the slime layer (as suggested by OFL - hope I'm paraphrasing correctly, with apologies if not!).
Did another water change today (day 5 of 2tsp/gallon Epsom salt regiment) and fed him lightly. He rests contentedly on his hammock, comes forward with cognitive stimulation (take top off tank, turn on lights, etc. and is otherwise BAR (bright/alert/responsive).
Will keep everyone posted!
