My betta fish Sol has recently got himself hurt somehow, probably on the little barrel I have inside his biorb bowl (4 gallons) so he can swim through, hide, and just have fun. Anyway I was wondering about salt baths, my big sister who had owned two betta's now (the second still alive the first one died, rip Mint~) said that salt baths can help repair things like that. I thought it was only for fin rot and such but she said it can help with torn fins as well. I know everything else about like how much aquarium salt to put in, how long to soak him and what to do after he's done soaking 2-5 minutes, just all that good stuff but I'm not sure how many times I should do it. Is it a daily thing? A weekly thing? Or a one time thing?
