So a couple weeks ago I noticed a minor case of Fin Rot just starting on one of my bettas. I took care of him right away and treated him and he got better and started healing.
So, last night I looked at my other betta after feeding him and noticed he has a rip right in the middle of his back fin. He is a veil tail and it was horrible to see that.
I did the pantyhose test before I put the plants and decorations in, and it has been the same decorations in with him for months.
Im not sure what he ripped it on, but it seems like a freak accident to me.
Now, how do I treat a split fin? Water changes to keep the water pristine? or do I have to use Aquarium Salt or something else?
