Hello all,
After keeping a Betta alive in a large, simple bowl for four years (many years ago) I have a new-ish Black Orchid in a tank with filter, heater, and ph and ammonia monitoring. He is solo. I thought this was a great environment for him, but within the last week, he developed small holes in the centers of his dorsal fin and tail fin which have progressed into large tears. I have read internet info for hours and I can’t find an explanation (or cure). Is it an injury that is worsening (maybe his fins got sucked into the filter intake?) or a type of rot that affects the middle of the fin instead of the edges? Thanks for any input.
