Who Gives A Fish Forums

Thanks so much, I really appreciate the advice. So I'm thinking of just running both the new and old filters together for 3-4 weeks to get the new one cycled, then I'll remove the old one - is that the best way to do it?

Thanks for the reply, that was my first thought as well. I'm pretty sure it's tail biting, but just to be on the safe side I'll add some aquarium salt after my water change today. I'm just not sure how much to add - any ideas for a 5 gallon tank?

Honestly, I'm at my wit's end with this fish. Got up today and noticed a pretty big chunk of my betta's tail is gone. Attached a couple of pics, not the best quality, but hoping someone can help me figure out if it's fin rot or tail biting.

I'm leaning towards the biting, to be honest, since it ...
