Hi, had these appearing on some of my mollies for months now. Only on about two fish at a time over about a year. The rest (about 20 mainly juveniles) are fine. It doesn't seem to spread throughout the community. It's never affected my neon tetras that have been in there for four years now nor the pleco. It's a well established aquarium (over five years old including filter) well maintained & water changed normally weekly (it's a 180lt tank). Filled up weekly via a chorine removing filter, same used in my other aquariums including a shrimp tank. My first thought is ammonia or nitrite but that's all fine. There's also no signs of water quality issues, I monitor the food intake which is probably a little under when putting in but fed three times a day. Live plants in there for years a few unwanted snails & some assassin snails. A planted aquarium substrate. Temperature about 24c to 25c
I had previously treated with anti bacterial waterlife and the anti viral over days but it never solved it. (Myaxazin & protozin)
Only other thing I can think of is that they're injuring themselves on something?
All the best
