How old is your fish (approximately)? I've had him for about a month and a half.
So my biggest curiosity that makes me think he may have bit them is there's no black edging. If anything, he has red in some spots. Which would be fine if he were a red fish. The red is on the end of two of the spines in his dorsal, which seems shorter now. He also developed a red line a couple weeks ago along another dorsal spine after flairing. Being that all his red is on thin/see though parts of his fin it seems like it might be trauma to the veins. His tail looks to be in perfect shape and I haven't seen him chase it. I'm afraid to try and QT him (away from his live plants) and treat him with any kind of salt because I won't be able to change the water over the weekend. (He's on my desk here at work.) I plan on changing most/all of his water again tomorrow before the weekend and if it's not showing signs of improvment on Monday, I'll QT him all week next week.
Does finrot ALWAYS have black edging? Do you think the red could go away someday? Will he be fine over the weekend?
I'll try to remember to grab my camera tomorrow and get some good pictures. (My phone doesn't focus well enough.)
Thank you for your thoughts and advice.
