Ok so since yesterday one of my tiger barbs had started to swim very eratically if that's how you spell it separated him self from the rest of the group (5 of them 6 in total) when he's not swimming he's looking down at about 90 degrees completely still he's been going upside down and this morning hes breathing very fast and twitching his body also looks like he's bending his body stiff at times as though he's dead but still breathing very fast, I've also noticed he's got internal red marks where I've marked on the pic, ps I can't get a good pic of the I'll one so jst pinched one of Google and edited it, tested water all is fine there all other fish are fine just done a 40% weekly water change. Any advice would be appreciated
