My local PetSmart gave me a betta that they were allegedly treating for finrot. The color change in four days is incredible. The finrot is gone. I did not treat him at all. I simply put him in some cycled tank water in a temporary holding tank while set up his new home. The first picture was taken 4/27/17. And the two on bottom were taken today, 5/1/17. I'm so blessed. I can't wait to see what color he develops.
