Roughly 2 1/2 months ago I picked up a halfmoon betta from the local petsmart. He seemed fine when I got him, but after about a month his ventrals almost completely fell off out of the blue, and right after that he got fin rot. I decided to start with the clean water treatment as I usually would. It helped him regrow his ventrals a bit, but the fin rot still hasn't gone away, his fins are beginning to get worse, and I'm getting a little concerned. Any reccomendations for treatment?

Sorry for the lousy pics, he never stops moving.

treat with aqarium salt for about five days and do a 100% water change every other days.

I am afraid the pictures have not come through correctly, are you able to try again?

As to treatment I suggest you first go with AQ salt as jjchiddick recommended which will cleanse the areas of infection and speed healing. If after a few days in this you still see signs of the rot working its way up the fins then the next step is a mild antifungal (many in the US on this site recommend jungle brand).

Keep us posted as to his progress.
