I am waiting to hear back from a friend about what this might be, but I know a lot of people are on the forums here and maybe this isn't species specific.. I just need to know if I need to quarentine right away
Its one of my female White cloud minnows, I flicked the light on the tank (to try and catch snails) and saw her. She's swimming normally and eating. My PH is 7.6 and my ammonia is 0, I did a partial water change today and changed my filter to a sponge (in the background you'll see my old filter and bio wheel to try and seed the new sponge faster).
The black spot on her tail is normal coloring.. this is the blackness of her body between her bottom fin and rear fin.
Hopefully you guys will have seen something like this before? She's the only one with it.
I didn't know if this should go here, or "Other Fishies" area, if I put it in the wrong spot ... sorry
