What are the differences between betta fin rot and tear, and how can they be distinguished from each other?

Betta fin rot is a bacterial infection that causes the fins to deteriorate and appear ragged, while fin tears are physical injuries that result in a clean, straight tear in the fin tissue. Fin rot is often accompanied by discoloration and inflammation, while fin tears do not show signs of infection. To distinguish between the two, look for signs of infection such as redness, inflammation, and deterioration in fin rot, while fin tears will appear as clean, straight tears without signs of infection.
