So I found these on my black skirt tetras fin last night, there are 10 black skirts, 10 Congo’s, 10 serpae tetra, 3 African brown knives and 5 Siamese algae eaters in here. This is the only fish affected and I’m deeply confused as to what this is...
The tank is densely planted and has been fully cycled and stocked for over 6 months with zero issue. Nothing new has gone into the tank, but I suppose it’s possible something from one of the QT tanks got crossed over through a net or something. But none of the QT fish have any similar symptoms.
These are the best pics I could manage, but he’s still very active so it was hard to get a still shot.
