Torn fin or rot?

[katydidmischief]

I did a water change today when I changed the tank around and I discovered a tear in his dorsal fin. I'm not sure if I should just leave him in the clean water (pH 7.2, Ammonia 0ppm) and monitor for a few days or if I should pick up something for fin rot?

It's one tear in the fin, none of the others appear to have any issue.

Check every surface in the tank to see if there are any mildly sharp edges.

If everything is clean assume disease also do a water change.

I did a change yesterday and swapped out most of his decor. There were some rough edges on his tiki house so everything he has now is smooth. Should I still do a water change today?

Thank you, ChoclateBetta!
