I have 3 clown loaches that came with a tank I bought. I have noticed recently that they seems to have black blotches / speckles / marks on them that I didn’t see before - not sure if I just missed them or they are new.
All my other fish appear to be healthy – the water is mature and is good quality. I have 2 large filters and a UV filter. Ph is about 6.8, No2 is 0, and temp 29C (did have discus in the tank so that’s why it’s high).
I have attached some pictures, but unfortunately however nicely I asked them they wouldn’t stay still so the quality isn’t great. The marks are on the fins mainly.
Please can someone tell me if there is something wrong or is this normal.
Thanks Matthew
