So, I saw this little red thing hanging off of Tintri yesterday, and I have no idea what it is. I've recently noticed red appearing in his fins as well (which you can see in the photos). I know its not Nitrite poisoning because the nitrite levels in the tank are 0ppm. I'm not sure if its Septicemia because he's showing no other symptoms. I thought maybe the red thing hanging off was just some weird shaped fecal matter. Well... I've seen him pass his food, and that thing is still there, so I know its not. I have no clue what it is.
He has a healthy appetite, he's as active as ever, and I've never seen him clamp. After loosing one of my fish only a few weeks ago, I really don't want to lose another. Especially not Tintri. So, please, help me if you can.
