I have a 4ft planted tank cycled and mature for a few years. Ammonia and nitrite 0, nitrate about 40. I have one yoyo loach about a year old (of 4) that is flashing on one side. He has been doing this since Christmas. It is mostly at feeding time and getting a little worse. He seems to be flashing on the body just below the top fin but I could be wrong. It seemed to start just after I got some plants which had a few snails.
For the life of me I can't see anything wrong, the skin looks good with no marks and no redness on the fins. Also no ich or spots. Eats well.
I'm treating for ich into the second week (~10 days). The tank temp went above 30C (86F) on the ~6th day but I'm using ich meds (Formalin and Malachite Green). Full dose. The loach has been flashing well before the ich and meds (unless it was in the gills).
Does anyone have any ideas what this could be and why the ich treatment is not helping? I'm suspecting a parasite but confused. Many thanks.
