about a week ago i noticed that my male bettas tail started to get fin rot. so i did some research and i read that using aquarium salt and keeping the water clean will help to get rid of it. so i've been cleaning his bowl everyday for the past 5 days and putting 1 1/2 teaspoons of dissolved aquarium salt in the water. but it seems like its just getting worse. the rips in his fins got longer, but the black seems to be going away. should i wait longer and continue with the aquarium salt or should i get some medicine from the pet store? He lives in a 1 gallon bowl at the moment because i want to get rid of his fin rot before i put him in the 10 gallon tank i have.
the water in his bowl is heated to 78-80 degrees fahrenheit. he swims,acts, and eats normally. some advice would be very appreciated :)
