my new betta got white spot a few days after i got him, so i added medicine following the directions in the instructions, it said add 1 treatment wait 4 days add a 2nd treatment and then the tank has to be left 7 days before you can treat again if needed. however, my betta has recovered but 2 days after the 2nd treatment all my tetra have white spot, and its a worse case than my betta had. should i follow the instructions carefully like it says or should i retreat the water now?
is fish medicine like human medicine where overdosing can be lethal?
