My betta got fin rot for the first time ever about a week ago. It was very fast moving, his fins were a bit tattered in the morning, and by the evening, looked like they got attacked! I cleaned his tank, a full water change, and treated the fresh water with BettaSafe as usual. His fins started to heal, but two days later started to tatter again.
I went out and got T.C. Tetracycline to treat him. Now the finrot is completely gone, and hes healthy but the medication made his water a nasty shade of brown and I'm all out of filters till this coming friday when i get paid.
My concern is what caused his finrot? I'm a college student, and my roommates betta got sick, and died for unknown reasons a week before my betta got finrot. She then bought a new baby betta halfmoon, who within a day got finrot, right around when mine got finrot. She has also since treated him, and hes healing.
My roomate has also taken to filling her tank with jugs of water she buys. From what I've heard though this is bad because of the mineral deficiencies of bottled water. However, she brought up the idea that maybe the pipes in our dorm are old and are what is giving our bettas finrot. My fish has never had finrot before
till i moved in here and cleaned the tank. Even though I treat the water with BettaSafe could this be the cause of the rot? If so, what can I do? It's the only water I have access to.
I need to clean his tank because the water is brown from the medication, but I'm afraid the fresh water will make his fins rot again! Help!
