Who Gives A Fish Forums

My betta loves his floating log. It's a cheap addition but gives him a place to hide and chill. Just something to think about when you're setting up the tank.

I'm pretty sure those high nitrate levels shredded his fins, but thankfully the water's back to normal after those sevelflake water changes. I've added more plants to improve the tank overall.
I'm still not sure if it's fin rot or just stress, though.
I've given him treatment already.
How long ...
