Symptoms and Treatment
How has your betta fish's appearance changed?
I removed his previous large plastic plant because I think he snagged his caudal fin on it. I noticed a few small rips in his tail which stopped occurring after it was removed. The rips started to “zip” up again. He showed no signs of fin rot (dark edges, etc.) and ammonia levels were under 5ppm when this happened.
Now… huge chunks of his caudal fin are missing (delta, by the way). His other fins are unaffected which leads me to suspect tail biting. He was showing no signs of fin rot or illness prior to this. The good news is he is showing some signs of regrowth (some translucent white fin).
How has your betta fish's behavior changed? Nope, still wants food, still wants to attack his reflection.
When did you start noticing the symptoms? Wednesday, checked on him and a lot of fin was just gone…
Have you started treating your fish? If so, how? Yes, .5 gallon water changes daily with some AQ salt added.
Does your fish have any history of being ill? Nope.
How old is your fish (approximately)? I’ve had him for about a month now.
I have yet to have catch him in the act of chasing his tail. I have added something for him to swim around (silk plant) to keep him occupied. I’ve been adding AQ salt to his water in small amounts (not going over 2 tsp total). He’s scheduled to have that in his water for another 2 days. I’ve also been debating adding a source of tannins. I don’t have access to any IAL or oak leaves (not pesticide-free ones anyway…) Are there any good substitutes besides those? Maybe a piece of Mopani wood or some decaf tea (would green be better due to the lack of processing?)
Just in case it is fin rot, I'll post some pictures once I can catch him... He doesn't stop moving...
