I waited for the salt to dissolve and then stirred the water around just to make sure. I think Ares is better now though...Would salt help repair tail fins because Ares is a crowntail and his rays have been melting?
You said Ares is pale right? Well, did you remember to pre-mix the salt? Un-dissolved salt can burn your Betta's fins. Did you also get him a hospital tank? Your Betta is probebly pale because of salt burn. Make sure that you get him into fresh de-chlorinated water at 80-82 degrees.
I would add the salt everyday for 5 days twice a day. 1 teaspooon per gallon. Make sure you feed him a protein-rich diet for those few days of treatment. Other than that, your Betta should be fine.
