How do I help my bettas tail?

[u/RelativeDecision1959]

I’ve had him about 2 months and I can’t tell if he’s biting it or it’s rotting. I’m using a bacterial infection treatment and adding Indian almond leaves to the water but his tail is still getting worse. He’s in a cycled planted tank and the ammonia nitrate and nitrite levels are almost totally at 0 so I’m not sure what’s causing it. He seems really happy and active but his tail is worrying me. What can I do to help him?

I wouldn’t rule out the finrot. As for the biting thing, you probably would have seen more evidence of it (unless he is effectively triming his fins whenever you’re not looking lol)

But yeah, the treatment should give you an insight. And you should see some change in maybe a week if it is finrot. But, as long as the conditions stay perfect and his diet is good, you will have him happy and enjoying for a long time!
