Firstly it's 400+ liters with Ammonia nil Nitrites nil. Temperature is 25C. Did a 75% water change with dechlorinator yesterday, nine other tiger barbs plus a severum are showing no trouble.
This tiger barb was spotted late this afternoon at the top of one corner of the tank, then began swimming in circles, tail up nose down and with an apparent 'S'-shape to the body. Breathing is rather labored and is flapping fins quite a lot.
Video (mobile phone quality - sorry) and pictures (the final pics are those of the affected fish).
Any ideas? He's currently all on his own in the far left corner at the very top although he is not gasping for air.
Another video - shows better his S-shape swimming in circles.
