I have a betta who has had blood streaks in his dorsal and anal fin for about a month now. At first I thought it was fin rot but he's got no blackened edges to his fins and no real tissue loss. He's just got these red blood streaks. He's white so it's very noticeable.
He's in a filtered, cycled, heated 5 gallon tank. The tank has been up for about 2 months now and I seeded it with filter media and gravel from my established 16 gallon. His params have almost always been 0,0,5. There were a couple of instances where I got a .25 or .5 ammonia reading and I changed the water until it was gone. Since then I've seen no ammonia or nitrite and very low nitrates. I normally do weekly water changes of 25% or so.
I treated him with 2 runs of Maracyn Plus when I thought it was fin rot. It had no effect. I'm wondering what I should do next? I'm willing to quarantine him and try another treatment. I've been keeping his water super clean. I change out 30% three times a week now. Still no change in the bloody streaks. He's otherwise active and eats just fine.
I have a pic if that would help. Any advice would be so appreciated.
