Hey guys, was watching one of my neon tetras, and he always seemed to be away from the shoal, always by himself at least 85% of the time whenever the lights were on. Also, his red strip has faded away, so now its almost transparent. I have quarantined him in my other tank *which is a shrimp tank* to see how things go, but I don't think it'll be getting any better. Just wanted to double check with you guys to see if my diagnosis is correct. He doesn't seem restless, but does spend a lot of time apart from the rest of the fellows. And his red line is almost color-less; its a very very light red now, with some transparent/white patches. Thanks!
