BellaOnline Forums Home and Garden Fish Please help my betta Filbert

Hey I have had my betta for almost a year now. He has had ich before and has cleared up fine. But now he has fin rot. I first thought the light red was the color at the ends of his fins due to his mixture of color but I was wrong \:\( Now his back fin is all torn up and is almost half the original size. He lives in a one gallon tank with a light and the temp stays around 80.I do a 50% water change every week then do a full change a week later. He has been fighting fin rot for about a week now. I am currently treating him in a smaller tank while I�m cleaning his other one. I�m using BettaFix and also keep aquarium salt in his tank. He hasn�t lost his color or appetite. I�m just so worried about him. I�m away from college and have no car if I have to go get more meds for him. Any more ideas?

I am by no means an expert on betta fish, I am in college as well and have a sick betta, so I've been frantically trying to get info online for a few days. I was changing my betta's one galleon bowl once every two weeks and using a turkey baster to take the poops out. I learned on another forum that I should be doing 30% water changes every other day and a 100% change once a week. Some links I found that were helpful in diagnosing my fish:

What kind of tank do you have your fishy in? Does it have a filtration system? Fin rot is usually from temperatures too cold - but your's has always been 80 degrees? Fin rot is also usually from not having the water clean enough consistently, so if you don't have a filter in his tank, the water would need to be changed more often in his specific case - maybe he's a big guy - what do you feed him and how often? That can effect how fouled up the water gets, too sometimes. I hope he is doing better. The little sweetie-pie!!!
