My betta fish has gotten Fin Rot. I'm mad at myself that I let him catch it. I went to the pet store and got some jungle fungus and aquarium salt. I am fully changing the water every other day, adding the fungus tablet, and salt. its been 4 days, I know nothing really would change but here whats getting me even more worried. when I put him back in the tank, it just started swimming around the edge attacking his reflection thinking is another betta fish. Also he hasn't eaten in 4 days, I dont want to lose him... what else can I do?
